Key Programming Using Diagnostic Equipment
Special Tool(s)
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 as 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 keys are to be programmed, refer to KEY PROGRAMMING 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 Owner Literature under the "Programming Spare (SecuriLock® North America, Safeguard ® U.K. or PATS for all other markets) Keys Procedure" for instructions on programming the remaining keys.
