Keyless Entry: Service and Repair

NOTE: The Anti-Theft Security Access Procedure is utilized to obtain Passive Anti-theft System (PATS) security access. PATS security access must be granted to erase ignition keys or enable/disable the spare key programming switch (PID SPARE KEY). The anti-theft security access procedure invokes a time delay prior to granting security access during which the scan tool must remain connected to the vehicle. Once security access has been granted, a security access command menu is displayed which offers various command options (For additional information, refer to Powertrain Control Module (PCM) Configuration Command Index).

1. Select SECURITY ACCESS. This procedure will take approximately 10 minutes to carry out, during which time, the ignition switch must be in the RUN position and the scan tool must be connected to the vehicle.
2. After the security access procedure has been completed, a new menu will be displayed with command options. Select the functions as required before exiting out of this menu. (Do not select more functions than the procedure calls for).
