Buick Lucerne 2007 - PASS-Key III+ Operation

Changes or modifications to this system by other
than an authorized service facility could void
authorization to use this equipment.
PASS-Key
®
III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key
®
III+ Operation
Your vehicle is equipped with PASS-Key
®
III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®
III+ is a
passive theft-deterrent system. This means you do
not have to do anything special to arm or disarm
the system. It works when you insert or remove the
key from the ignition.
When the PASS-Key
®
III+ system senses that
someone is using the wrong key, it prevents
the vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
When trying to start the vehicle if the engine does
not start and the security light on the instrument
panel cluster 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 not damaged, try another ignition
key. At this time, you may also want to check the
fuse, see Fuses and Circuit Breakers on page 429.
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/
retailer 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 466.
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. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®
III+ to have
keys made and programmed to the system.
