Customer bought a car that needed different a different key for the ignition to the driver’s door. This is rebuilding the customer’s door lock to match all the other locks on the vehicle
If your car has been stolen/recovered without the keys you may wish to have the locks changed and the missing keys electronically erased from the vehicle. This will prevent any missing keys being used to re-steal the car.
One of the most common ways to steal a car is by taking the keys. Do not leave your keys within sight of the letterbox. I go to so many houses to see the keys hanging in full view, or lying on the hallway table.
