Sentry Key Immobilizer System
WARNING: This page is about a different car, the 2009 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
The Sentry Key Immobilizer System (SKIS) is standard factory-installed equipment on this vehicle. The SKIS provides passive vehicle protection by preventing the engine from operating unless a valid electronically encoded key is detected in the ignition lock cylinder.
The SKIS includes the following major components, which are described in further detail elsewhere in this service information:
- Security Indicator - A security indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). Refer to Electrical - Instrument Cluster/Instrument Cluster - Description .
- Sentry Key Remote Entry Module (5) - The Sentry Key REmote Entry Module (SKREEM) (also known as the Sentry Key Immobilizer Module/SKIM or the Wireless Control Module/WCM) is located on the right side of the steering column near the ignition lock cylinder housing and an integral molded plastic antenna ring circles the ignition lock cylinder like a halo. The SKREEM and its antenna are concealed beneath the shrouds on the steering column. See Electrical - Vehicle Theft Security/Vehicle Theft Security/MODULE, Sentry Key Immobilizer (SKREEM) - Description .
- Sentry Key Transponder - The Sentry Key transponder is contained within the Remote Keyless Entry (RKE) transmitter integral to the head of the ignition key. See Electrical - Vehicle Theft Security/Vehicle Theft Security/KEY, Transponder - Description .
