Sentry Key Immobilizer System Initialization

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The Sentry Key Immobilizer System (SKIS) must be initialized following a Radio Frequency Hub Module (RFHM) (also known as the RF Hub) 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 Chrysler Customer Center.

NOTE:

If the Powertrain Control Module (PCM) (also known as the Engine Control Module/ECM) is replaced on a vehicle equipped with the Sentry Key Immobilizer System (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.
