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/retailer.
Your dealer/retailer can reprogram your vehicle so lost
or stolen transmitters no longer work with your vehicle.
Each vehicle can have a maximum of four transmitters.
Two recognized transmitters are required for Canadian
owners.
To match a new transmitter to your vehicle when you
have a recognized transmitter:
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.
6. Place the new, unrecognized transmitter into the
transmitter pocket with the transmitter buttons facing
the front of the vehicle. The transmitter pocket is
inside the center console storage area located
between the driver and front passenger seats.
