Locksmith Serge
Lock Rekey Service in Los Angeles
New keys for locks that are still in good shape.
If the lock is damaged or you want different hardware, that is a lock change or a repair. Call or text 622-399-7156 to confirm availability.
What rekeying a lock does
Rekeying changes which keys operate a lock that is still sound. Inside the cylinder, the pins or tumblers are set so a new key works and the old keys do not. The lock body stays on the door. Locksmith Serge is a mobile lock and key service. When the job is a fit, we do that work at the house or apartment in Los Angeles.
People ask for a lock rekey after a move, after extra keys have been copied, or after a lockout when the hardware itself is fine. This page stays on that keying job. It is not a lock-replacement article, and it is not a repair article for a lock that will not turn.
Not every lock can be rekeyed. Compatibility depends on the lock type and its condition. Share what is on the door when you call so we can talk through whether rekeying looks possible.
Rekey versus lock change
Rekey means new keys and the same lock. A lock change means the hardware comes off and a different lock goes on. If you want a new finish, a different function, or the old lock is too worn to keep, use lock change and replacement. If you only need the keys to change, stay here.
When rekeying is a good fit
Rekeying is a good conversation when you have moved into a home and do not know who still has keys, when too many copies are in circulation, or when you are back inside after a lockout and the lock still works. A deadbolt and a keyed knob can often be discussed the same way if both are compatible.
Rekeying is the wrong first page when the lock is broken, loose, or will not latch — that is closer to lock repair. It is also the wrong page when you want a different kind of lock, including a keypad or smart deadbolt. Those jobs have their own pages.
Office or storefront rekeying belongs on commercial locksmith service. This page stays on home locks.
Common rekey situations
These cards stay on changing which keys work. Broken hardware or a new lock type is a different page.
Moved into a home
You have the lock on the door and want a new key so earlier copies no longer work. That is a rekey when the hardware is still sound.
Too many keys in circulation
The lock still works. You want old copies to stop. Rekeying is about the keys, not swapping the whole lock.
The lock is failing
A lock that sticks, binds, or will not latch needs the hardware looked at. That is closer to lock repair than a rekey.
You want different hardware
A new finish, a different function, or a lock that should come off entirely is a lock change, not a rekey of the same cylinder.

What helps a rekey visit go smoothly
A few practical details that make a lock rekey call clearer.
The hardware is still the point
Rekeying keeps a lock that works. If the lock is failing or you want a different one, we point you to repair or change.
The door details come with you
How many locks, what they look like, and whether you want them to work on the same new key — if they are compatible — helps the call.
Work is done at the house
When the job is a fit, rekeying happens at the door, not as a shop drop-off first.
Related jobs stay on their own pages
A lockout is entry. A lock change is new hardware. Repair is a fault. This page stays on new keying.

Lock rekey questions
Does rekeying replace the lock?
No. Rekeying keeps the lock on the door and changes which keys operate it. Replacing the hardware is a lock change. Say which one you want when you call.
Will my old keys work after a rekey?
They should not. The point of a rekey is that the old keys stop working and a new key operates the lock. Keep a new key somewhere safe after the visit.
Can you rekey several doors to one key?
Sometimes, when the lock types match and are compatible, more than one lock can be keyed alike. That is not a master-key system. We confirm what is possible after we know what is on each door.
Is rekeying cheaper than replacing the lock?
It depends on the lock and the job. Some locks are a straightforward rekey. Some are not worth keeping. Call with what is on the door and we can talk through which path looks like a fit.
Can a smart lock be rekeyed like a deadbolt?
Not in the same way. A mechanical cylinder rekey is this page. A keypad or smart deadbolt is a different product and a different conversation. Use the smart lock installation page if that is the hardware you want.
Should I rekey after I move into a Los Angeles rental?
If you have permission to change who can enter, rekeying is a common request when you do not know who still has keys. Confirm you can authorize the work. We are not interpreting a lease — only asking that the person who calls can approve the job.
