Sentry Key Immobilizer System

The SKIS includes 2 valid Sentry Key transponders from the factory. These 2 Sentry Keys can be used to program additional non-coded blank Sentry Keys. These bank 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 8 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 scan tool.
