Questions & Answers

Used-Car Key Security Check: Common Questions

How do I know if extra keys are programmed to my car?

On many vehicles our programmer can show how many keys are stored in the car. If the number is higher than the keys you received, someone else may still have a working key.

Can you remove a key I don't have?

Yes. On request we delete old keys from the car's memory and program the keys you hold, so a missing key can no longer start the vehicle.

Does deleting a key stop it from opening the doors?

Deleting a key stops it from starting the car. On some vehicles the metal blade of an old key can still open a door lock — ask us about your vehicle when you call.

Do you need proof of ownership?

Yes. We check the registration or title with your ID before any key work. A real locksmith always does.

Can you add a spare at the same time?

Yes. Many dealers hand over only one key with a used car. We can delete unknown keys and add a spare in the same visit.
