Key Programming - Erase All Key Codes and Program Two Keys
WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This procedure is used when a customer needs keys programmed into the system and does not have two programmed ignition keys available. This procedure is also useful when programmed ignition key(s) have been lost or a new ignition switch assembly has been installed, and it is desired to erase key(s) from the passive anti-theft system (PATS) memory.
NOTE:
This procedure will erase all programmed ignition keys from the vehicle memory and the vehicle will not start until two keys have been reprogrammed to the vehicle.
NOTE:
Two PATS encoded keys with the correct mechanical cut must be available to carry out this procedure. One or both of them may be the customer's original keys.
NOTE:
If additional (more than two) keys are to be programmed, see KEY PROGRAMMING - PROGRAM A KEY USING TWO PROGRAMMED KEYS . If the remaining keys are with the customer and are not available with the vehicle, then instruct the customer to refer to the owners literature under the "Programming Spare [SecuriLock®(r) (North America), Safeguard ®R (U.K.) or PATS for all other markets] Keys Procedure" for instructions on programming the remaining keys.
