Sentry Key Immobilizer System

This vehicle is using Advanced Encryption Standard (AES) to implement the immobilizer system. Secret codes are stored in the Radio Frequency Hub (RFH), Body Control Module (BCM), and the Powertrain Control Module (PCM) that allows these modules to execute the MiniKrypt immobilizer routine. The key fobs, via transponder mode only, are married to the RFH.

If the vehicle is remotely started, this is a mode that is recognized by the immobilizer system and it will not being authentication until after the vehicle exits from the remote start mode.

The immobilizer process does not take place until after the Security Gateway Module (SGW) has been successfully authenticated for information regarding the SGW and its role in vehicle security on this vehicle. Refer to MODULE, SECURITY GATEWAY (SGW), DESCRIPTION .
