Sentry Key Immobilizer Module Programming

CAUTION: Large metallic objects, or items such as magnetic pass-keys, may cause vehicle starting problems. These devices do not cause damage to system. Devices may cause intermittent malfunctions if positioned too close to ignition lock cylinder during vehicle start-up. Move objects away from ignition lock cylinder and try to start vehicle.
NOTE: If the PCM and the SKIM are replaced at the same time, program the VIN into the PCM first. All vehicle keys will then need to be replaced and programmed to the new SKIM.
