KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT

Worldwide Diagnostic System (WDS):

Special Tool(s)

NOTE:
- This procedure is used when a customer needs keys programmed into the system and does not have 2 programmed ignition keys available. This procedure is also useful when a programmed ignition key(s) is lost or a new ignition switch assembly is installed, and it is desired to erase key(s) from the passive anti-theft system (PATS) memory.
- This procedure erases all programmed ignition keys from the vehicle memory and the vehicle does not start until 2 keys are programmed to the vehicle.
- 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.
- 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's Guide 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. Using Two Programmed Keys

5. Insert the first encoded key into the ignition lock cylinder and turn the ignition switch to RUN for 3 seconds.
6. Insert the second encoded key into the ignition lock cylinder and turn the switch to the RUN position for 3 seconds.
