Programming with a
Recognized Key
To program a new key:
1. Insert the original, already
programmed key in the ignition
and turn the key to the ON/
RUN position.
2. Turn the key to LOCK/OFF,
and remove the key.
3. Insert the new key to be
programmed and turn it to the
ON/RUN position within
five seconds.
The security light will turn off
once the key has been
programmed.
4. Repeat Steps 1 3 if additional
keys are to be programmed.
If a key is lost or damaged, see your
dealer to have a new key made.
Programming without a
Recognized Key
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that 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 you wish to program 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
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.
I n f o r ma t i o n P r o v i d e d b y :
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.
With an active OnStar subscription,
an OnStar Advisor may remotely
unlock the vehicle. See OnStar
