How to Rekey a Car Door Lock
A rekey car door lock service changes the internal pins inside the lock cylinder so that only a new key will work; your existing locks and hardware stay in place. It's the most cost-effective security step when you've lost a car key, suspect someone has a copy of your key, or bought a used vehicle and want to be sure you're the only one with access.
If you're looking up how to rekey a car door lock yourself, it's technically possible with a pin tumbler kit matched to your exact cylinder, but a single misplaced pin can lock you out of your own car. Most drivers in Los Angeles skip the trial and error and call a mobile locksmith who already carries the right pins and tools on the truck.

Rekeying vs. Lock Replacement
Rekeying a car is different from replacing the locks. When you rekey, the cylinder is modified to accept a new key pattern; the hardware itself isn't replaced. This keeps costs low while restoring your security. If your locks are damaged or worn, we may recommend cylinder replacement instead, which we also offer.
