Jaguar glove box lock with key code number stamped on the base of the lock. I can re-key the lock insert if the lock has been changed. Also photocopy of directions to remove the lock insert out of the ignition switch. You have to insert the key and press the BRASS pin on the side of the switch.
I can de-code a cut key based on a good photo or a tracing of your present key.
Good picture of a American key blank, de-coded based on the cut of the key.
