14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE If the SKIM indicator light comes on during normal vehicle operation (it 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. NOTE: • The Sentry Key Immobilizer System is not compatible with remote starting systems. Use of these systems may result in vehicle starting problems and loss of security protection. • Mobil Speedpass™, additional Sentry Keys, or any other transponder equipped components on the same keychain will not cause a key-related (Transponder) fault unless the additional part is physically held against the ignition key being used when starting the vehicle. Also, cell phones, pagers, or other RF electronics will not cause interference with this system. All of the keys provided with your new vehicle have been programmed to the vehicle electronics. Important Note About Service A four digit PIN number is needed to service the Sentry Key Immobilizer System. This number can be obtained from your authorized dealer. However, this number can also be found on your customer invoice that you were given upon receipt of your vehicle. Replacement Keys NOTE: Only keys that have been programmed to the vehicle electronics can be used to start the vehicle. Once a Sentry Key has been programmed to a vehicle, it cannot be programmed to any other vehicle.
