Sentry Key Immobilizer System Initialization
The Sentry Key Immobilizer System (SKIS) must be initialized following a Radio Frequency Hub Module (RFHM) replacement. SKIS initialization requires the use of a diagnostic scan tool. Initialization will also require that you have access to the unique four-digit PIN code that was assigned to the original RFHM. The PIN code must be used to enter the Secured Access Mode in the RFHM. This PIN number may be obtained from the vehicle owner, from the original vehicle invoice or from the Customer Center. Refer to STANDARD PROCEDURE .
If a Powertrain Control Module (PCM) is replaced on a vehicle equipped with the SKIS, the unique Secret Key data must be transferred from the RFHM to the new PCM using the appropriate programming procedure. This procedure also requires the use of a diagnostic scan tool and the unique four-digit PIN code to enter the Secured Access Mode in the RFHM. Refer to the appropriate diagnostic information for the proper PCM programming procedures.
