Sentry Key Immobilizer System
WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Sentry Key Immobilizer System (SKIS) also uses tactile beep support from the chime warning system. The Sentry Key Immobilizer Module (SKIM) is programmed to send chime request messages over the Programmable Communications Interface (PCI) data bus to the Body Control Module (BCM) to provide audible confirmation that the SKIM has been successfully placed in the Customer Learn mode and a new Sentry key transponder has been successfully programmed by the SKIM. For more information and testing, see appropriate ANTI-THEFT SYSTEMS article.
