THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13 • 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. At the time of purchase, the original owner is provided with a four digit PIN number. This number is required for dealer replacement of keys. Duplication of keys may be performed at an authorized dealer or by using the Customer Key Programming procedure. This procedure consists of programming a blank key to the vehicle electronics. A blank key is one which has never been programmed. NOTE: When having the Sentry Key System serviced, bring all vehicle keys to the dealer. Customer Key Programming You can program new keys to the system if you have two valid keys by doing the following: 1. Cut the additional Sentry Key Transponder blank(s) to match the ignition switch lock cylinder key code. 2. Insert the first valid key into the ignition switch and turn the ignition switch ON for at least 3 seconds but no longer than 15 seconds. Turn the ignition switch OFF and remove the first key. 2
