The Sentry Key REmote Entry Module (SKREEM) is sometimes referred to as the Wireless Control Module (WCM). The SKREEM/WCM is the
primary component of the Sentry Key Immobilizer System (SKIS). It is also the receiver for the Remote Keyless Entry (RKE) system. The
SKREEM/WCM is located on the steering column, around the ignition lock cylinder housing and is concealed beneath the steering column shrouds. The
molded black plastic housing for the SKREEM/WCM has an integral molded plastic halo-like antenna ring (3) that extends from one side. When the
SKREEM/WCM is properly installed, the antenna ring is oriented around the ignition lock cylinder housing.
A single connector (1) is located next to the antenna ring on the SKREEM/WCM housing. A molded plastic mounting tab (2) on the SKREEM/WCM
housing secures the unit to the steering column. The SKREEM/WCM is connected to the vehicle electrical system through the instrument panel wire
The SKREEM/WCM cannot be adjusted or repaired. If faulty or damaged, the entire SKREEM unit must be replaced.
