PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (PersonalizedAutomotive Security System) theft-deterrent system.PASS-Key®III+ is a passive theft-deterrent system.
The system is automatically armed when the keyis removed from the ignition.
The system is automatically disarmed when the key isturned to ON/RUN, ACC/ACCESSORY or STARTfrom the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problemwith arming or disarming the theft-deterrent system.
When the PASS-Key®III+ system senses that someoneis using the wrong key, it prevents the vehicle fromstarting. Anyone using a trial-and-error method to startthe vehicle will be discouraged because of the highnumber of electrical key codes.
If the engine does not start and the security light comeson when trying to start the vehicle, there may be aproblem with your theft-deterrent system. Turnthe ignition off and try again.
If the engine still does not start, and the key appears tobe undamaged, try another ignition key. At this time,you may also want to check the fuse, seeFusesand Circuit Breakers on page 6-101. If the engine stilldoes not start with the other key, your vehicle needsservice. If your vehicle does start, the first key may befaulty. See your dealer/retailer who can service thePASS-Key®III+ to have a new key made. In anemergency, contact Roadside Assistance.
It is possible for the PASS-Key®III+ decoder to “learn”the transponder value of a new or replacement key.Up to 10 keys may be programmed for the vehicle.The following procedure is for programming additionalkeys only. If all the currently programmed keys arelost or do not operate, you must see your dealer/retaileror a locksmith who can service PASS-Key®III+ tohave keys made and programmed to the system.
