Programming without a
Recognized Key (Key
Vehicles Only)
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that Canadian owners see
their dealer.
If there are no currently recognized
keys available, follow this procedure
to program the first key.
This procedure will take
approximately 30 minutes to
complete for the first key. The
vehicle must be off and all of the
keys must be with you.
1. Insert the new vehicle key into
the ignition.
2. Turn to ON/RUN. The security
light will come on.
3. Wait 10 minutes until the
security light turns off.
4. Turn the ignition to LOCK/OFF.
5. Repeat Steps 2 4 two more
times. After the third time, turn
to ON/RUN; the key is learned
Keys, Doors, and Windows
and all previously known keys
will no longer work with the
vehicle.
Remaining keys can be learned by
following the procedure in
Programming with a Recognized
Key (Key Vehicles Only).
The key has a bar-coded key tag
that the dealer or qualified locksmith
can use to make new keys. Store
this information in a safe place, not
in the vehicle.
See your dealer if a replacement
key or additional key is needed.
If it becomes difficult to turn a key,
inspect the key blade for debris.
Periodically clean with a brush
or pick.
