Matching Transmitter(s) to Your Vehicle Each Keyless Access System is coded to allow only transmitters programmed to your vehicle to work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer. Your dealer can reprogram your vehicle so lost or stolen transmitters no longer work with your vehicle. Each vehicle can have a maximum of four transmitters matched to it. To match a new transmitter to your vehicle when you have a recognized transmitter, do the following. Two recognized transmitters are required for Canadian owners. 1. The vehicle must be off. 2. Have the recognized transmitter and the new, unrecognized transmitter(s) with you. 3. Insert the vehicle key into the key lock cylinder located on the outside of the driver's door. 4. Turn the key to the unlock position five times within five seconds. 5. The Driver Information Center (DIC) will display READY FOR FOB X, where X can be 2, 3 or 4. 90
