Sentry Key Remote Entry System

The Sentry Key Remote Entry System (SKREES) provides passive vehicle protection by preventing the engine from operating unless a valid electronically encoded key is detected in the ignition lock cylinder. The SKREES used in combination with the export premium version of the VTSS adds a steering shaft lock feature that provides passive protection by preventing the vehicle from being steered unless a valid electronically encoded key is detected in the ignition lock cylinder.

The SKREES includes the following major components, which are described in further detail elsewhere in this service information:

• Powertrain Control Module  - The Powertrain Control Module (PCM) is located in the engine compartment.
• Sentry Key Remote Entry Module (SKREEM)/Wireless Control Module (WCM)  - The Sentry Key Remote Entry Module (SKREEM), sometimes referred to as 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 instrument panel steering column shrouds.
• Sentry Key Transponder  - The Sentry Key transponder is contained within the Remote Keyless Entry (RKE) transmitter on the ignition key.
• Security Indicator  - The security indicator is integral to the ElectroMechanical Instrument Cluster. Refer to OPERATION .
• Shaft Lock Module  - A shaft lock module is located on the lower end of the steering column casting below the instrument panel in the passenger compartment of vehicles built for sale in certain export markets where it is required equipment.
