2-12 Keys, Doors, and Windows
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys can
be programmed for the vehicle. The
following procedure is for
programming additional keys only.
Canadian Owners: If the keys are
lost or damaged, only a dealer can
service the theft-deterrent system to
have new ones made. Two current
driver's keys are required to
program additional keys.
To program a new key:
1. Verify that the new key has
PK3+ stamped on it.
2. Insert the current driver's key in
the ignition and start the engine.
If the engine does not start see
your dealer for service.
3. After the engine has started, turn
the key to LOCK/OFF, and
remove the key.
4. Insert the second current driver's
key in the ignition and start the
engine within ten seconds of
removing the previous key. If the
engine does not start see your
dealer for service.
5. After the engine has started, turn
the key to LOCK/OFF, and
remove the key. Insert the key to
be programmed and turn it to
ON/RUN within ten seconds of
removing the previous key.
The security light turns off once
the key has been programmed.
6. Repeat Steps 1 through 5 if
additional keys are to be
programmed.
If the security light comes on and
stays on while driving, the engine
will restart if you turn it off. However,
the theft-deterrent system is not
working properly and must be
serviced by your dealer. The
vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 or Roadside
Assistance Program (Mexico) on
page 13‑10.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
