Buick 2007 Terraza - Manual (Page 127)

The starter will not work and fuel will stop being
delivered to the engine. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
If the engine does not start and the security
message comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key
appears to be undamaged, try another ignition key.
At this time, you may also want to check the
instrument panel PASS KEY fuse. If the engine still
does not start with the other key, your vehicle
needs service. If your vehicle does start, the first
key may be faulty. See your dealer or a locksmith
who can service the PASS-Key
® III to have a new
key made. See Fuses and Circuit Breakers on
page 497.
It is possible for the PASS-Key
® III decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
This procedure is for learning additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer or a
locksmith who can service PASS-Key
® III to have
keys made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
® III to get a new key blank that is
cut exactly as the ignition key that operates the
system.
To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed
key into the ignition lock cylinder and start the
engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to
LOCK and remove the key.
4. Insert the key to be programmed and turn it to
RUN within 10 seconds of removing the
previous key.
5. The security message will turn off once the
key has been programmed. It may not be
apparent that the security message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys
are to be programmed.
