Description - Sentry Key Immobilizer System
WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles equipped with this option can be readily identified by a gray molded rubber cap on the head of the ignition key. Models not equipped with SKIS have a black molded rubber cap on the head of the ignition key.
The SKIS includes the following major components, which are described in further detail elsewhere in this service information:
- Powertrain Control Module
- Sentry Key Immobilizer Module (Refer to OPERATION - VEHICLE THEFT SECURITY SYSTEM )
- Sentry Key Transponder
- Security Indicator (Refer to SECURITY INDICATOR ).
Except for the Sentry Key transponders, which rely upon Radio Frequency (RF) communication, hard wired circuitry connects the SKIS components to the electrical system of the vehicle.
