Rekey vs. Change Locks: What's Best for Your New Metro Detroit Home?

Just moved into a new home in Metro Detroit? One of the first things you should do is secure your new property. But should you rekey your locks or change them entirely? We break down the differences for Michigan homeowners.

March 10, 2026 8 min read Metro Detroit locksmith

Congratulations on your new home in Metro Detroit! Whether you've settled in Detroit, Troy, Dearborn, or Birmingham, securing your property should be at the top of your to-do list. When it comes to your exterior doors, you have two main options: rekeying your existing locks or completely changing them out. Understanding the difference is key to making the right decision for your peace of mind and budget.

What Does "Rekeying" Mean?

Rekeying a lock means changing the internal pins and springs within the lock cylinder so that the old key no longer works, and a new key does. The lock hardware itself (the knob, lever, or deadbolt body) remains the same. It's a cost-effective and efficient way to ensure that anyone with a copy of the old key – previous owners, contractors, neighbors, etc. – can no longer access your home.

  • Pros of Rekeying:
  • Cost-Effective: Generally less expensive than replacing entire lock sets.
  • Faster: A skilled locksmith can rekey multiple locks quickly.
  • Maintains Aesthetics: Keeps your existing door hardware, which is useful if it matches your home's style or if you have high-quality locks.
  • Keyed-Alike Option: We can often rekey all your exterior doors (front, back, garage) to operate with a single new key, simplifying your life.
  • Cons of Rekeying:
  • Doesn't Upgrade Security: If your current locks are old, worn, or low-security models, rekeying won't make them more robust against forced entry.
  • Limited to Existing Hardware: You're stuck with the style and functionality of your current locks.

What Does "Changing Locks" Mean?

Changing locks means removing the entire lock assembly (knob, lever, deadbolt) and installing brand new hardware. This is a more comprehensive solution that involves replacing the lock cylinder as well as the visible parts of the lock.

  • Pros of Changing Locks:
  • Enhanced Security: An opportunity to upgrade to higher-security locks (e.g., Grade 1 deadbolts, pick-resistant cylinders, smart locks).
  • Improved Aesthetics: You can choose new lock styles and finishes to match your home's updated look.
  • New Functionality: Install locks with new features like keypads, smart home integration, or different handle styles.
  • Addresses Wear and Tear: Replaces old, sticky, or damaged locks with fresh, smooth-operating hardware.
  • Cons of Changing Locks:
  • Higher Cost: Replacing multiple lock sets can be significantly more expensive than rekeying.
  • More Time-Consuming: Installation takes longer than rekeying.
  • Potential for Complications: Sometimes new locks don't perfectly fit old door preparations, requiring adjustments.

When to Rekey vs. When to Change in Metro Detroit

Rekey Your Locks If:

  • You just moved in: This is the most common reason. You have no idea who might have old keys, so rekeying all exterior doors is crucial for immediate security.
  • You lost your keys: If your keys are gone, rekeying is a must to prevent unauthorized access.
  • You had a falling out: If a former roommate, employee, or contractor still has keys, rekeying is the solution.
  • Your current locks are in good condition: If you have solid, modern locks that function well, there's no need to replace them.
  • You want all your doors on one key: A locksmith can rekey multiple locks to operate with a single master key.

Change Your Locks If:

  • Your locks are old, rusty, or damaged: Worn-out locks are easier to compromise and can be frustrating to use.
  • You want to upgrade security: If your current locks are basic builder-grade or low-security models, changing them to higher-grade locks provides better protection.
  • You want a different style or finish: Updating your hardware can significantly improve your home's curb appeal.
  • You're installing smart home technology: This is the perfect opportunity to integrate smart lock install features.
  • You've experienced a break-in: After a burglary, it's often best to replace compromised locks entirely, and perhaps upgrade to more robust options.

After a Break-In in Detroit: Rekey or Replace the Locks?

If the door was kicked in or pried, replace the damaged lock and fix the strike and frame first: rekeying a lock that was forced does not make the door hold again. If the burglar got in without forcing anything, rekey every exterior door, because a key or an unlocked door was the way in. Forced entry is by far the common case in the city. Detroit Police Department open data records 2,335 forced-entry burglaries from January 1 to September 28, 2026, against 617 entries without force, and August's 306 forced entries were the highest monthly count of the year so far.

If the door was kicked in or pried

  • Look at the frame before the lock: a kicked door usually fails at the strike, where short screws pull out of the jamb or the jamb splits. A split jamb needs a carpenter first, or a new deadbolt has nothing solid to throw into.
  • Replace a damaged deadbolt, do not rekey it: a bolt that no longer throws all the way, or a cylinder that was pried, drilled, or twisted, cannot be trusted again.
  • Upgrade the strike: a heavy-duty strike plate fastened with long screws into the stud behind the jamb is what holds against the next kick. Ask for one when the replacement deadbolt goes in.

If nothing was forced

  • Rekey every exterior door: front, back, side, and the door from the attached garage, ideally to one new key. An entry without force usually means a key was out there: a lost set, a spare under the mat, a former tenant, or a contractor.
  • Reset every code the same day: garage keypads, smart-lock user codes, and any app access you shared, and delete users you no longer recognize.

Either way, get the police report number and photograph the damage before anything is repaired. Your claim will ask for both.

In depth

Frequently asked questions about metro detroit locksmith articles work across Metro DetroitTap to read the full guide: common questions and how we work in Metro Detroit.

The questions below come straight from the calls and texts our dispatchers field every day from customers across Metro Detroit. They are written to help you make a good decision before you hire any locksmith — not just us.

How fast can a real locksmith reach me in Metro Detroit?

Under normal traffic conditions our nearest mobile unit is roughly 15 to 30 minutes from any address in Metro Detroit. Rush-hour traffic on I-75, I-94 or I-696 can push the upper end of the range out by another 10 minutes. We will give you a live ETA the moment you call, not a vague "on the way." If your situation is unsafe — a child or pet locked inside a car or home, for example — say so when you call; we route those jobs ahead of routine ones.

What should a locksmith put in writing?

A proper locksmith invoice lists the service performed, the parts installed by manufacturer and model, the labor, any after-hours charge, and the total. It also names the company and the technician. If a "locksmith" on the phone offers a teaser service-call price and refuses to put anything else in writing, you are talking to a call center, not a locksmith. Walk away. Bait-and-switch is the single most common locksmith scam in Southeast Michigan.

How do I know who is coming to my door?

Before anyone arrives, the dispatcher tells you who is coming and when. Every job ends with a written receipt that names the company, the technician and the work performed. If anything about a visit does not match what you were told on the phone, call (313) 236-4558 before any work starts. We recommend asking these questions of any locksmith before they touch your hardware.

What does a locksmith visit cost?

It depends on the job: the type of lock or vehicle, the hardware involved, the time of day, and whether parts are needed. We screen jobs carefully on the phone so the technician arrives with the right parts and the right tools, and we explain the work before it starts. Call (313) 236-4558 for a price on your job.

Will you drill my lock?

Almost never on a routine residential or automotive lockout. Drilling is reserved for the small percentage of jobs where the lock is genuinely damaged, the cylinder is anti-pick high-security hardware, or a key has been broken off in a way that cannot be extracted. When drilling is the right call, we tell you in advance, explain the replacement cylinder before we start, and complete both the entry and the new install in a single visit. A locksmith who arrives and immediately reaches for the drill on a standard residential deadbolt is either inexperienced or running a scam — either way, send them home.

Can you rekey my locks to match a single key?

Yes. Rekeying is one of the most common requests in Metro Detroit — usually after a move-in, a roommate change, a contractor handover, or a vacation-rental turnover. We can rekey most pin-tumbler residential locks (Kwikset, Schlage, Defiant, Baldwin, Weiser, Yale residential, and many smart-lock backups) to a single key, and on commercial hardware we can rekey to a small master-key system that gives one master key to ownership and unique keys to staff. Rekeying is dramatically cheaper than replacing locks and the security level is identical when done correctly.

What smart locks do you recommend and install?

We install most major-brand smart locks and keypad locks: August, Yale Assure, Schlage Encode and Sense, Kwikset Halo, Level Bolt and Level Lock+, Aqara U100/U200, Lockly, and Ultraloq. We do not push a single brand — the right choice depends on your door, your Wi-Fi situation, whether you use Apple Home / Google Home / Alexa, whether you want a physical keyway as backup, and how the rest of your home is set up. We always leave a working mechanical keyway when one exists so you are never locked out by a dead battery or a service outage.

Do you handle commercial storefront and panic hardware?

Yes. Storefront aluminum doors with hook bolts and pivot hardware, narrow-stile deadbolts (Adams Rite and clones), panic and exit devices (Von Duprin, Detex, Falcon, Yale), electric strikes, magnetic locks, and door closers are all standard work for our commercial techs. We do new installs, repairs, and rekey/keying changes, and we can put a small storefront on a simple master-key system in a single visit. Our commercial customers in Metro Detroit include retail, restaurants, medical offices, dental practices, fitness studios, churches, schools, and property managers.

Can you replace a car key or program a fob?

For the overwhelming majority of late-model Toyota, Honda, Lexus, Acura, Ford, GM, Chrysler, Jeep, Hyundai, Kia, Nissan, Mazda, BMW, and Tesla vehicles — yes, on-site, anywhere in Metro Detroit. We carry transponder blanks, remote head keys, and proximity (smart) fobs and program them to your VIN with manufacturer-grade equipment. A handful of high-end European vehicles still require a dealer visit; we will tell you up front when that is the case so you do not waste a trip.

Do you do safe lockouts and combination changes?

Yes — residential gun safes, fire safes, floor safes, drop safes, and many commercial safes. Most safe lockouts are resolved without destructive entry by manipulating the lock or using a documented manufacturer override. We can also change combinations on most mechanical and electronic safe locks. Safe work is one of the higher-skill areas of locksmithing and is exactly where experience shows.

Do you serve property managers and HOAs?

We work with dozens of property-management companies and HOA boards across Metro Detroit, including Metro Detroit when applicable. We can be added as a preferred vendor, work from a single PO or master-services agreement, invoice on net-30 terms, and provide standardized after-hours response for tenant lockouts. Master-key planning, key control logs, and standardized hardware specs are all part of the package.

What payment do you accept?

All major credit cards (Visa, Mastercard, American Express, Discover), debit cards, Apple Pay, Google Pay, Zelle, and cash. For commercial accounts we offer invoicing on net-15 or net-30 terms after a short qualification process. Every transaction generates a written receipt.

Is there a guarantee on the work?

Yes. Labor is guaranteed for 90 days against workmanship issues. Hardware is covered by the manufacturer's warranty — typically 1 year on entry-level locks and up to a lifetime mechanical / 5-year electronic warranty on premium hardware (Schlage, Yale, Kwikset SmartKey, Level, Baldwin). If anything we touched stops working as expected within the guarantee window, we come back and fix it.

What should I have ready when I call?

A few things speed the job up dramatically: a photo of the lock, key, or vehicle in question; the year, make, and model of any car involved; the address with a gate code or building entry if applicable; and a method of payment ready when the tech arrives. For commercial jobs add the contact person on site and any access restrictions. We can run the job without any of this — but with it, you usually save 10–15 minutes.

What if I just want a second opinion on work another locksmith proposed?

Send us a photo of the paperwork and the hardware. We will tell you, plainly, whether the proposed work makes sense for the hardware, whether the parts list is honest, and whether the company looks like a legitimate locksmith or a call-center operation flipping the job to a subcontractor. The locksmith industry has more than its share of bad actors. You do not have to hire us afterwards.

Still have a question that's not here? Text us a quick photo or message at (313) 236-4558. A real locksmith will reply — usually within minutes during business hours, and first thing the next business day for anything urgent.

How BH Locksmith Metro Detroit handles metro detroit locksmith articles work across Metro Detroit

Every job follows the same simple sequence regardless of where in Metro Detroit it sits on the map. You call or text us — usually with a photo if you can manage it — and a real dispatcher (not a call center, not a bot) gathers the basics: address, hardware, urgency, and any access notes. From there we route the closest mobile unit to your location and give you a live ETA and a technician name. If a company will not tell you who is coming or what the job involves until the tech gets there, that is a tell of the call-center operations that scam customers across Southeast Michigan every single day.

On arrival the technician confirms the hardware in front of you, walks you through the job, and only then starts the work. For residential lockouts that means picking, bumping, or shimming the lock open without damaging the keyway. For automotive lockouts it means using a wedge and reach tool — never breaking a window or punching a lock. For commercial storefronts it means working the latch or the panic bar from the outside whenever the door geometry allows. Drilling is reserved for genuinely damaged or high-security cylinders, and even then we explain the replacement first and complete both jobs in the same visit so you have a working door at the end.

Smart-lock installs follow a longer checklist because there is more to verify: door alignment and gap, deadbolt throw, strike-plate condition, Wi-Fi signal strength at the door, hub or bridge placement, and integration with whatever ecosystem you already use (Apple Home, Google Home, Alexa, Samsung SmartThings, Aqara, or Hubitat). We always leave the mechanical keyway functional when one exists. A smart lock that requires an app to open the front door is one firmware update or one dead battery away from a lockout — that is not a security upgrade, it is a downgrade.

Commercial work in Metro Detroit typically starts with a brief site survey — usually fifteen minutes — where we walk every entry, photograph the existing hardware, and confirm the lock manufacturer, cylinder type, and any electronic access components in use. From there we write up a door-by-door plan of the hardware and the proposed warranty terms. Property managers and HOA boards often add us as a preferred vendor at this stage so future after-hours calls route to us automatically rather than to whichever ad-spend "locksmith" happens to be ranking that day.

Master-key planning deserves its own paragraph because it is one of the highest-leverage things a small business owner can do. A properly designed master-key system lets one master key open every cylinder while individual employees carry keys that only open their own zones — front of house, back of house, office, supply room, server closet. When an employee leaves you re-pin only their sub-zone instead of replacing every lock in the building. We design these systems on paper before any pins move, deliver written keying schedules, and provide a key-control log for management. The labor cost is often recovered the first time someone walks out with a key.

What drives the cost of a job in Metro Detroit is the same in every city and neighborhood: the type of job, the hardware involved, the time of day, and whether parts are needed. A lockout is mostly time and skill. A rekey depends on how many cylinders you have. A smart-lock install depends on whether you supply the lock or want us to bring one. Automotive key replacement depends on the year, make and model, because a 2008 transponder key and a 2023 proximity fob are very different jobs. Call (313) 236-4558 for a price on your job.

The paperwork matters too. Before any work starts, ask for the company name, the technician's name, and a plain description of the job, and check that the name on the invoice matches the name you called. If anything goes wrong on a job, a clear paper trail is the first thing your landlord, HOA or insurer will ask for. We encourage you to ask these questions of every locksmith you call, including us.

Finally, a note on how to compare locksmiths. A legitimate locksmith puts the company name, a description of the work, and the manufacturer and model of any parts on paper, and the total on the invoice already includes any after-hours charge. If someone offers a teaser service-call price over the phone and the technician arrives asking for far more without explanation, that is the textbook locksmith scam pattern. Send the technician away, call us, and we will give you a real second opinion. We do this several times a week. It is one of the genuinely useful things a real locksmith can do for Metro Detroit, and we are happy to do it whether or not you end up hiring us.

A few practical notes worth knowing before you call any locksmith in Metro Detroit. Keep a spare key with someone you trust — a neighbor, a family member three towns over, a co-worker. It is the simplest protection against a lockout, and it can save you an after-hours call entirely. If you own your home, consider a small mechanical lockbox bolted to a side gate or hidden in your backyard with a code only you and one other person know; this is what real estate agents use and it works fine for a personal spare too. If you rent, ask your landlord or property manager for the official building procedure for after-hours lockouts before one happens — many buildings have a contracted locksmith or front-desk procedure that is faster than calling around at 2 a.m.

For car owners, the most important thing you can do is keep the make, model, year, and VIN of your vehicle written down somewhere that is not inside the car. Programming a new fob or transponder requires the VIN, and an unhelpful lock-screen on a dead phone in a locked car is the single most common reason a simple key replacement turns into a long, expensive day. Take a picture of your registration card and store it in a notes app or print it and keep it in your wallet. It takes a minute and can save you hours when you need it.

For small business owners, the analog is a documented key plan. Even a one-page spreadsheet that lists every door, every key, who holds it, and when it was last rekeyed will save you a great deal of trouble the first time an employee leaves under bad circumstances. A good locksmith will help you write this during the first install. We do this all the time across Metro Detroit. The customers who plan this once never have to think about it again; the ones who do not end up calling us at midnight after an HR incident and paying a premium to rekey every door in the building before opening hours the next morning.

We hope this is useful whether or not you end up hiring BH Locksmith Metro Detroit. The locksmith industry in Southeast Michigan has a reputation problem and the only durable fix is for customers to be better-informed and for legitimate locksmiths to publish honest answers in writing, which is exactly what this page tries to do. If you want a second opinion on work someone proposed, a recommendation on a smart lock, or just an honest answer about whether you actually need our service: text (313) 236-4558. A real local locksmith will reply.

A quick history of the locksmith trade in Southeast Michigan

Locksmithing in Southeast Michigan goes back more than a century, and the trade has changed more in the last thirty years than in all the decades before. The reason customers need to be careful is simple: too many bad actors, too little accountability, and a long series of consumer scams that left homeowners and small business owners with empty wallets and damaged doors. The best protection is a few plain questions. Ask for the company name and make sure it matches the invoice. Ask who is coming and when. Ask what the job involves before any work starts. A locksmith on your driveway who cannot answer those questions is not someone to let near your door. It is that simple.

Metro Detroit in particular has a long history with the locksmith trade because of the mix of housing stock, commercial density, and the sheer number of vehicles registered in the county — more than two million at last count. The result is steady demand across all segments and a marketplace where the difference between a real locksmith shop and an out-of-state lead-generation operation matters enormously. The unfortunate trend over the last decade has been the rise of national dispatch companies that buy paid ads against local search terms, take the customer call, and then flip the job to whoever bids lowest on a contractor exchange — frequently an individual with no real connection to the brand on the ad. We are the opposite of that model. Same team, same number, same trucks, every time.

Hardware standards have evolved fast too. Twenty years ago a residential entry-door lock was a pin-tumbler cylinder that took two minutes to pick and another two minutes to bump. Today the same door might carry an anti-bump pin stack, a high-security keyway with restricted blanks, a Bluetooth radio for app integration, and a Z-Wave or Thread mesh-network module for whole-home automation — all in a package that looks identical to its 1990s ancestor from outside. The skill ceiling for a working locksmith has gone up accordingly. We train continuously on new hardware, attend the major industry events (ALOA, the SAVTA safe technicians convention, regional smart-home shows), and keep current on every major brand we install. When a customer asks "can you work on this lock," the answer is almost always yes — and if it is no, we tell you on the call rather than discover the problem on your driveway.

Automotive locksmithing has changed even more dramatically. The transponder revolution of the late 1990s — when manufacturers started embedding a chip in the key that the ignition module had to recognize — broke the traditional "copy-the-cuts" locksmith model for cars and forced everyone in the trade to invest in programming equipment, software subscriptions, and OEM-grade key blanks. The proximity-fob revolution of the 2010s did it again, and the rolling-code immobilizer cryptographic upgrades of the last few years have done it once more. The result is that car-key replacement, which used to be a quick trip to the hardware store, is now a piece of skilled mobile-technical work requiring professional programming equipment and constantly updated software. A locksmith who tells you they can do car keys but cannot tell you which brand of programming tool they use is bluffing. We use Autel and Topdon as our primary platforms with brand-specific add-ons for the harder vehicles. Ask any locksmith the same question before you let them touch your car.

On the smart-home side the same pattern of consolidation and standardization is finally arriving. Matter — the cross-vendor smart-home protocol backed by Apple, Google, Amazon, Samsung, and most major manufacturers — is making it possible to install one smart lock and have it work natively with whatever ecosystem the homeowner happens to use. Thread, the low-power mesh-networking layer underneath Matter, is reaching enough density in new homes that locks like the Aqara U200 and Yale Assure SL with Matter Module behave reliably out of the box. We pay attention to this because the most common complaint about smart locks five years ago — "it kept disconnecting" — has finally been solved at the protocol layer rather than the brand layer. If you bought a smart lock in 2019 that gave you headaches, the 2025 generation is genuinely different.

For commercial customers the analogous story is electronic access control. The traditional "wired prox-card reader and a server in the closet" model is being replaced by cloud-hosted platforms — Brivo, Openpath (now Avigilon Alta), Kisi, Verkada, Salto KS — that let a property manager add or revoke a credential from a phone in seconds. We install and service the major platforms and can usually retrofit a working mechanical-lock building onto a cloud-controlled access system without replacing every door. The cost-saving for a small business that previously rekeyed cylinders every time someone left is significant; the security improvement from real-time logging and instant credential revocation is even bigger.

For everything we touch, our written policy is the same: leave the property at least as secure as we found it, document the work, hand over keys and credentials in person, and stand behind the install. The locksmith trade has had to earn customer trust the hard way after decades of bad actors flooding the search results, and the way we earn it is by doing exactly what we said we would do, on time and in writing. That standard is portable across all of Metro Detroit, and it is the reason our company name and phone number are on every page of this site and every invoice we send.

One small thing worth saying explicitly: we are a small, local business. There is no offshore call center and no national franchise in the middle. That model, a national paid-search operation flipping calls to whichever bidder is cheapest that hour, is the entire reason consumer reports keep flagging the locksmith industry as one of the most-scammed service categories in the United States. We have spent years building the alternative: a real shop with real trucks, real techs, and a single phone number that reaches the people who do the work. If you are comparing locksmiths in Metro Detroit, please at least check that each candidate gives you a real company name before you book. The difference between a teaser service-call ad and a company that puts its name on the invoice is the difference between getting your door open and getting your wallet cleaned out.

If you got this far in the page, thank you for reading. Most people will scroll past everything below the call-to-action and grab the phone number, and that is exactly what these pages are for — they exist so the people who do read have a thorough, honest answer to the questions that come up before they pick a locksmith. We did not write any of this to fill space. It is the answer we would want if we were on the other side of the door, locked out at midnight, deciding which name on the first page of search results was worth trusting with our property. If something here helped you make a better decision — about us or about any other locksmith — that is the entire point.
