Removal and Installation
NOTE: When a new lock cylinder is installed, the door lock cylinder and ignition lock cylinder should be installed as a set. This eliminates carrying an
extra key which will fit only one lock. If a new key is used, the new key code number is stamped on a metal tag attached to the key.
1. Insert the key into the ignition lock cylinder and turn it to the RUN position.
2. Using a suitable tool, press the ignition lock cylinder release pin and remove the ignition lock cylinder.
3. For vehicles equipped with Passive Anti-Theft System (PATS) , if a new lock cylinder with keys is replaced, the new PATS keys must be
programmed. For additional information, refer to Key Programming Using Diagnostic Equipment in Antitheft and Alarm Systems. See:
Accessories and Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Programming and Relearning/Key Programming Using
Diagnostic Equipment
4. To install, reverse the removal procedure.
