Sentry Key Immobilizer Module: Description
The Sentry Key Immobilizer Module (SKIM) is the primary component of the Sentry Key Immobilizer System (SKIS). The SKIM is located on the right side of the steering column, below the ignition lock cylinder housing and is concealed beneath the steering column shrouds. The housing for the SKIM has an molded plastic halo-like antenna ring. 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 connector containing six terminal pins is located on the opposite end of the SKIM from the antenna ring. A stamped metal mounting bracket secured to the SKIM housing is used to secure the component to the right lower flange of the steering column jacket.
The SKIM cannot be adjusted or repaired. If faulty or damaged, the entire SKIM unit must be replaced.
