Lock Rekeying in Buffalo, NY: Who Has a Key to Your Place Right Now?
When most people think about home or business security, they picture a break-in. But the bigger everyday gap usually isn’t a forced door, it’s all the keys to your place already sitting in other people’s pockets and junk drawers. The previous owner. Their grown kids. The contractor who did the kitchen. A realtor’s lockbox. An old roommate. Rekeying is how you take that control back, fast and cheap, without buying a single piece of new hardware.

What rekeying actually is, and what it isn’t
People mix up rekeying and replacing all the time, so let’s clear it up.
Same lock, new key, old keys dead
Inside every standard lock is a row of little pins set to match one key pattern. Rekeying means we pop the cylinder, swap those pins to a new pattern, and cut you a new key to match. The lock itself stays right where it is, bolted to your door. What changes is which key opens it. The second we’re done, every old key that used to work is just a useless piece of brass. That’s the whole point, and it’s why a lock rekeying Buffalo NY job costs a fraction of replacing the hardware.
Who has a key to your place right now?
Once you start counting, the list is usually longer than you’d think. Here’s when rekeying earns its keep.
You just moved in
This is the big one. When you buy or rent a place, you have no real idea how many keys are out there. The sellers, their family, neighbors who watered the plants, every contractor who worked on it, and the lockbox the agent used during showings. A residential locksmith Buffalo NY can rekey the whole house in one visit so you’re the only one who can get in. It’s the first thing we tell new homeowners to do.
A tenant or roommate moved out
Landlords know this routine. Every time a tenant turns over, those keys should stop working, and you can’t count on getting every copy back. Rekeying between tenants is faster and cheaper than new locks, and it keeps your rental secure for the next person. Same goes for a roommate who moved out of a shared place.
You lost a key or went through a breakup
If a key is truly lost, the worry isn’t just getting in, it’s who might have found it. And after a breakup or a falling-out, rekeying makes sure the only person with access to your home is you. It’s a small, quiet step that puts your mind at ease.
Staff turnover at your business
For a business, keys walk out the door with employees all the time. A commercial locksmith Buffalo NY can rekey your locks when someone leaves so an old key can’t get them back inside after hours. For bigger operations, we set this up as a system, which we’ll get to in a minute.
Rekey or replace? Here’s how to decide
Plenty of people rip out perfectly good locks and buy new ones when a rekey would’ve done the same job for a lot less. Here’s how to tell which you actually need.
When rekeying is the smart call
Rekey when the locks themselves are in good shape and you just need the old keys to stop working. New home, tenant turnover, lost key, staff change, a key you want killed off. The hardware’s fine, you only need to reset who holds the key. This covers most situations, and it’s the cheaper route every time.
When you actually need new locks
Replace when the lock is worn out, damaged, broken into, or just old and weak. If you’re upgrading to high-security locks or you want a different style or finish, that’s a new lock installation too. We’ll always tell you straight which way makes sense for your door instead of selling you hardware you don’t need.
One key for the whole place
Here’s something a lot of people don’t know rekeying can do. If your house has three different keys for the front, back, and garage, we can rekey all of them to open with a single key. It’s called keying them alike, and it means one key in your pocket instead of a jingling handful. For businesses, the bigger version is a master key system, where one master opens everything and each person’s key opens only what they should. We set both up.
“When somebody buys a house, they’ll spend a fortune on the place and never think about the fact that the old owner, their kids, the contractors, and a realtor’s lockbox all had keys. Rekeying is a few dollars a lock to make every one of those keys useless. It’s the cheapest peace of mind in the trade.”
What we rekey
If it takes a key, odds are we can rekey it. That covers:
- House deadbolts, knob and lever locks, and most residential hardware
- High-security locks and the better-grade cylinders
- Commercial door locks, storefront cylinders, and office hardware
- Keying multiple locks alike so one key opens them all
- Master key systems for businesses with staff and multiple doors
- Mailbox locks, padlocks, and the smaller stuff people forget about
If you’re locked out on top of needing a rekey, we can handle the house lockout and the rekey on the same visit, since we’re already there.

How to make sure you’re hiring a real locksmith
You’re handing someone control of who gets into your home or business, so who does the work matters. New York consumers get burned regularly by national dispatch outfits that pose as local shops, quote a low price on the phone, send an unmarked subcontractor, and run the bill up once the work’s done. The New York Attorney General’s office tracks complaints like these every year.

Questions Buffalo homeowners and businesses ask us
What’s the difference between rekeying and replacing a lock?
Rekeying keeps your lock and changes the key it answers to, so old keys stop working. Replacing swaps the whole lock for new hardware. Rekeying is cheaper and works great when the lock is in good shape.
I just bought a house. Should I rekey?
Yes, and right away. You have no way of knowing how many keys the old owners, their family, contractors, and agents have. A rekey in one visit makes you the only person who can get in.
Can you make all my locks open with one key?
We can. We rekey them to the same pattern so a single key opens the front, back, and garage. For a business, we can set up a full master key system instead.
Do you rekey commercial locks too?
Yes. We rekey storefront, office, and commercial hardware, which is the quick way to cut off a former employee’s access without replacing locks.
Do you come to me?
We do. We’re fully mobile, so lock rekeying happens right at your door anywhere in Buffalo, Erie County, or Niagara County.
