18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE NOTE: • The Sentry Key Immobilizer system is not compatible with aftermarket remote starting systems. Use of these systems may result in vehicle starting problems and loss of security protection. • Exxon/Mobil Speedpass™, additional RKE transmitters, or any other transponder-equipped components on the same key chain will not cause a fault unless the additional part is physically held against the RKE transmitter being used to start the vehicle. Cell phones, pagers, or other RF electronics will not cause interference with this system. All of the RKE transmitters provided with your new vehicle have been programmed to the vehicle electronics. Replacement Keys NOTE: Only RKE transmitters that are programmed to the vehicle electronics can be used to start and operate the vehicle. Once an RKE transmitter is programmed to a vehicle, it cannot be programmed to any other vehicle. CAUTION! Always remove the keys from the vehicle and lock all doors when leaving the vehicle unattended. At the time of purchase, the original owner is provided with a four-digit Personal Identification Number (PIN). Keep the PIN in a secure location. This number is required for authorized dealer replacement of RKE transmitters. Duplication of RKE transmitters may be performed at an authorized dealer or by using the Customer Key Programming procedure. This procedure consists of programming a blank transmitter to the vehicle electronics. A blank transmitter is one that has never been programmed.
