Key Programming Using Diagnostic Equipment

KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT

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 the ignition lock cylinder is replaced, and it is desired to erase key code(s) from the passive anti-theft system (PATS) memory.
NOTE:This procedure erases all programmed ignition keys from the vehicle memory. The vehicle will not start until a minimum of 2 keys are programmed into the instrument cluster.
NOTE:A minimum of 2 PATS keys must be programmed into the instrument cluster before the vehicle will start.
NOTE:Two PATS encoded (contains a transponder) 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, and the remaining keys are with the customer, or are not available, instruct the customer to see the Owner's Literature for instructions on programming the remaining keys. In this case, the PID SPAREKEY must be enabled.
NOTE:This procedure is not necessary if only the PATS transceiver was replaced. Replacement of the transceiver does not erase the PATS key codes in the instrument cluster.
1. Turn the key from the OFF position to the ON position.

2. Select instrument cluster from the IDS or equivalent tester menu. Follow the anti-theft security access procedure to obtain security access. For additional information, See .

3. From the IDS or equivalent tester menu select: IGNITION KEY CODE ERASE.

4. Turn the key to the OFF position and disconnect the IDS or equivalent tester.

5. Insert the first PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds.

6. Remove the first PATS key from the ignition lock cylinder.

7. Insert the next PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds. The vehicle will now start with both keys.

8. If it is desired to program additional key(s) (only up to 8 keys total can be programmed into the instrument cluster), See Key Programming Using Two Programmed Keys for each additional key that needs to be programmed.

9. Start the vehicle with all of the programmed keys to verify their operation.
