Keyless Entry Module: Description and Operation
The functions and features of the Sentry Key Immobilizer Module (SKIM) (also known as the Sentry Key REmote Entry Module/SKREEM or the
Wireless Control Module/WCM) are all integral to the Wireless Ignition Node (WIN) (1) in this vehicle. The WIN is the primary component of the
Sentry Key Immobilizer System (SKIS). It includes the integral ignition switch and is also the receiver for the Remote Keyless Entry (RKE) system and
the Tire Pressure Monitor (TPM) system. The WIN is located in the instrument panel, just to the right of the steering column. The remainder of the WIN
including its mounting provisions and electrical connections are concealed within the instrument panel.
The WIN cannot be adjusted or repaired, but is flash update capable. If ineffective or damaged the entire WIN must be replaced. See: Accessories and
