Sentry Key Immobilizer System
WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Sentry Key Immobilizer System (SKIS) includes the following major components, which are described in further detail elsewhere in this service information:
- Powertrain Control Module (PCM)
- Sentry Key Remote Entry Module (SKREEM)
- Sentry Key Transponder
- SKIS 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. Refer to the appropriate wiring information in ELECTRICAL.
