Operation
To unlock the driver’s door, press the UNLOCK button.
The interior lamps will come on for 40 seconds or until
the ignition is turned on. If you press the UNLOCK
button again within five seconds, the passenger door
will unlock.
Press the LOCK button to lock both doors. The interior
lamps will come on for two seconds as soon as all the
doors are closed. If you press the LOCK button twice
the horn will chirp to confirm that the doors have
locked. This will only occur if the transmitter has been
programmed with the ignition off.
If you do not want the horn to chirp as a confirmation
that the doors have locked or unlocked, please consult
your dealer.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only two transmitters
matched to it.
