Sentry Key Immobilizer System

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.
• A new Sentry key transponder has been successfully programmed by the SKIM.

See the owner's manual in the vehicle glove box for more information on the features, use and operation of the SKIS. Refer to Sentry Key Immobilizer System  in Description and Operation of the service information - Vehicle Theft/ Alarm systems for more information on the SKIS. For diagnostic information, refer to the Powertrain Diagnostic Information.
