Programming Transmitters to
the Vehicle
Only RKE transmitters programmed
to the vehicle will work. If a
transmitter is lost or stolen, a
replacement can be purchased and
programmed through your dealer.
The vehicle can be reprogrammed
so that lost or stolen transmitters no
longer work. Any remaining
transmitters will need to be
reprogrammed. Each vehicle can
have up to eight transmitters
matched to it.

Transmitter (Key Vehicles Only)
To program a new key:
1. Insert the original, already
programmed key in the ignition
and turn the key to the ON/

2. Turn the key to LOCK/OFF and

times. After the third time, turn
