The Sentry Key Immobilizer Module (SKIM) (1) is the primary component of the Sentry Key Immobilizer System (SKIS). This module contains a Radio Frequency (RF) transceiver and a central processing unit, which includes the Sentry Key Immobilizer System (SKIS) program logic. The SKIM is located on the right side of the steering column, near the ignition lock cylinder housing and is concealed beneath the steering column shrouds. The molded black plastic housing for the SKIM has an integral molded plastic halo-like antenna ring (4) that extends from the bottom. When the SKIM is properly installed on the steering column, the antenna ring is oriented around the circumference of the ignition lock cylinder housing.

A single integral connector receptacle (3) is located just behind the antenna ring on the bottom of the SKIM housing. An integral molded plastic mounting tab (2) on the rear corner of the SKIM housing has a hole in the center through which a screw passes to secure the unit to the steering column. The SKIM is connected to the vehicle electrical system through a single take out and connector of the instrument panel wire harness.
