Rekey Locks in Dallas, TX
Rekey existing locks in Dallas — keep the hardware, change the key, lower cost than a lock change.
Rekey is the most underused service in residential locksmith work. Most homeowners assume they need new locks when they really just need a rekey — same hardware, new key, lower bill.
This page explains when rekeying is the right call, when it isn’t, and what it actually involves for a typical Dallas home or business.
Common situations we handle
- You just bought or rented a new home in Dallas and you want to reset who has access.
- Lost the only set of keys and want to make sure they no longer work.
- Old roommate or tenant moved out and you want to be sure they no longer have a key.
- Multiple locks at different ages — you want all doors keyed alike to one new key.
- Property manager turning over a unit between tenants.
- Recent break-in attempt — want the locks reset without buying new hardware.
How the service works
- Call us with the number of locks, the brand if you know it, and whether you want all locks keyed alike.
- We confirm price per cylinder and an ETA.
- Technician arrives with the right pin kits and key blanks.
- We disassemble each lock, replace the pins, and cut new keys.
- We test each lock with the new keys, hand them to you, and confirm the old keys no longer work.
Rekey vs lock change — what's actually right
Rekey changes which key opens the lock without replacing the lock itself. It's faster, cheaper, and uses the hardware you already have. Lock change replaces the entire lock — appropriate when the hardware is worn out, the brand is too cheap to trust, or you want a different style or finish. For most Dallas homeowners who just moved in, rekey is the right answer.
Keying alike
If your house has separate keys for the front door, back door, garage entry, and side gate, we can rekey all of them to use one key — assuming the locks are compatible (same brand family, similar pin counts). This is usually no more expensive than separate keys and makes life dramatically easier.
When rekey isn't possible
Very cheap builder-grade locks, locks with damaged cylinders, or locks past their service life are not worth rekeying. We'll tell you on-site if a particular lock should be replaced rather than rekeyed — the cost difference is usually small.

Frequently asked questions
How long does a rekey take?
Most home rekeys (2–6 doors) take under 90 minutes on-site. Larger jobs scale linearly.
Will I get new keys at the end?
Yes. We cut a fresh set of keys for the new pin configuration. The old keys stop working.
Can you keep the same key I have if I want?
No — that's the whole point of rekeying. The new keys are different from the old ones.
Can you rekey smart locks?
Yes, almost always. Smart locks have a mechanical override cylinder that can be rekeyed even though the lock also uses an electronic code.
Do I need to rekey if I just lost one key?
If you know where you lost the key (e.g. inside the house) probably not. If the key could be in a stranger's hands, yes.
What if I have a really old lock?
Sometimes it can be rekeyed, sometimes the pins are too worn. We'll tell you on-site whether rekey or replacement is the better choice.
