Sentry Key Remote Entry Module (SKREEM) Overview

The Sentry Key Remote Entry Module (SKREEM) combines the Sentry Immobilizer Module (SKIM) and the Remote Keyless Entry (RKE) Module into one module system that performs the functions of both modules. Refer to the Body diagnostic information manual for all RKE related diagnostic information.

The SKREEM is designed to prevent unauthorized vehicle operation. The system consists of a SKREEM, ignition key(s) equipped with a transponder chip and PCM. When the ignition switch is turned on, the SKREEM interrogates the ignition key. If the ignition key is Valid or Invalid, the SKREEM sends a PCI Bus message to the PCM indicating ignition key status. Upon receiving this message the PCM will terminate engine operation, or allow the engine to continue to operate.
