Spare Key Programming

NOTE: Replacement PATS modules require only one key to be programmed before allowing vehicle to start. If PATS module is replaced, any additional keys must be programmed. PATS module has capacity to store programming for 16 keys.

Cycle ignition switch from RUN to OFF position with a programmed key. Within 15 seconds after this cycle, insert a new encoded key into ignition switch and turn key to RUN position. THEFT indicator light will illuminate for 2 seconds. Spare key is now programmed and PATS module will enable vehicle to start when this key is used.
