THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15 Key-In-Ignition Reminder Opening the driver's door when the key is in the ignition, sounds a signal to remind you to remove the key. NOTE: With the driver's door open, and the key in the ignition, both the power door locks and Remote Keyless Entry (RKE) will not function. SENTRY KEY The Sentry Key Immobilizer System prevents unauthorized operation of the vehicle by disabling the engine. The system will shut the engine off after 2 seconds of running if an invalid key is used to start the vehicle. This system utilizes ignition keys which have an electronic chip (transponder) embedded into them. Only keys that have been programmed to the vehicle can be used to start and operate the vehicle. The Sentry Key Immobilizer System does not need to be armed or activated. Operation of the system is automatic regardless of whether or not the vehicle is locked or unlocked. During normal operation, the Theft Alarm/ Immobilizer Light will come on for three (3) seconds immediately after the ignition switch is turned on for a bulb check. Afterwards, if the bulb remains on, this indicates a problem with the electronics. If the bulb begins to flash after the bulb check, this indicates that an invalid key has been used to start the vehicle. Both of these conditions will result in the engine being shut off after two (2) seconds of running. Keep in mind that a key which has not been programmed is also considered an invalid key even if it is cut to fit the ignition lock cylinder for that vehicle. If the Theft Alarm/Immobilizer Light comes on during normal vehicle operation (vehicle has been running for longer than 10 seconds), a fault has been detected in the electronics and the vehicle should be serviced as soon as possible. 2
