Buick 2005 LaCrosse - Manual (Page 92)

When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED warning message
on the Driver Information Center (DIC) 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 fuse. See Fuses
and Circuit Breakers on page 5-88. If the engine still
does not start with the other key, the vehicle needs
service. If the vehicle does start, the first key may be
faulty. See your dealer who can service the
PASS-Key
® III to have a new key made. In an
emergency, contact Roadside Assistance. See Roadside
Assistance Program on page 7-6 for more information.
It is possible for the PASS-Key ® III decoder to accept
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional keys
only. If all the programmed keys are lost or do not
operate, see your dealer or a locksmith who can service
PASS-Key
® III to have keys made and programmed
to the system.
To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master key in the ignition 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 OFF,
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within five seconds of removing the original key.
5. The STARTING DISABLED warning message on
the DIC will turn off, once the key has been
programmed. It may not be apparent that the
STARTING DISABLED warning message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If the STARTING DISABLED warning message appears
and stays on the DIC while the vehicle is being
driven, the engine will be able to be restarted if it is
turned off. Your PASS-Key
® III system, however, is not
working properly and must be serviced by your
dealer. The vehicle is not protected by the
PASS-Key
® III system at this time.
If the PASS-Key ® III key is lost or stolen, see your
dealer or a locksmith who can service PASS-Key ® III to
have a new key made.
