Sentry Key Immobilizer System

The SKIS includes two valid Sentry Key transponders from the factory. These two Sentry Keys can be used to program additional non-coded blank Sentry Keys. These blank keys can be cut to match a valid ignition key, but the engine will not start unless the key transponder is also programmed to the vehicle. The SKIS will recognize no more than eight valid Sentry Key transponders at any one time. The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will store Diagnostic Trouble Codes (DTC's) if a system malfunction is detected. The SKIS "can be diagnosed, and any stored DTC can be retrieved using a DRB III(R) scan tool as described in the BODY DIAGNOSTIC PROCEDURES - CONCORDE, 300M & INTREPID .
