Sentry Key Immobilizer System
WARNING: This page is about a different car, the 2002 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
With the SKIS, an electronically coded ignition key sends a signal through the SKIM to other modules on the PCI Bus. If a valid signal is received by the PCM, vehicle will start and continue to run. If the signal is invalid, the vehicle will start and run for 2 seconds, then shut off. After six unsuccessful attempts at starting, the SKIS will shut down until a valid key is used. If vehicle is equipped with SKIS, ignition key will have a Gray molded rubber cap. Models not equipped with SKIS will have a Black molded rubber cap on the head of the ignition key. For additional information on SKIM and SKIS, see ANTI-THEFT SYSTEMS - DAKOTA article.
