Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your GM dealer. Remember to
bring any additional transmitters so they can also
be re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. The vehicle can
have a maximum of four transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
The KEY FOB BATT LOW message in the vehicle’s
DIC will display if the remote keyless entry transmitter
battery is low.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
2-6

To replace the battery in the remote keyless entry
transmitter, do the following:
1. Insert a at object, with a thin edge, into the notch
located below the remote alarm button, and
separate the bottom half from the top half of the
transmitter.
2. Remove the old battery. Do not use a metal object
to do this.3. Slide the new battery into the transmitter with the
positive side of the battery facing up. Use a type
CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so
water will not get in.
5. Test the operation of the transmitter with
the vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It may also start up the vehicle’s heating or
air conditioning systems and rear window defogger.
When the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the key is turned
to RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
2-7

Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
Your vehicle’s remote keyless entry transmitter, with the
remote start button, provides an increased range of
operation. However, the range may be less while
the vehicle is running and as a result, you may need to
be closer to your vehicle to turn it off, than you were
to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry System on page 2-3for additional information.
The remote vehicle start feature needs to be reset after
your vehicle’s engine is started two times using the
transmitter’s remote start button. The remote start
system is reset by Inserting the vehicle’s key into the
ignition lock cylinder and turning it to RUN and then to
OFF. SeeIgnition Positions on page 2-21for
information regarding the ignition positions on
your vehicle.

then immediately press and hold the transmitter’s
remote start button until the turn signal lamps ash
or for four seconds, if the vehicle’s lights are not
visible. The vehicle’s doors will lock.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the engine is running.
The engine will shut off automatically after
10 minutes, unless a time extension has been done
or the vehicle’s key is inserted into the ignition
lock cylinder and turned to RUN.
4. To manually shut off a remote start, do any of the
following:
Aim the remote keyless entry transmitter at the
vehicle and press the remote start button until
the parking lamps turn off.

If you enter the vehicle after a remote start, and the
engine is still running, insert the key into the ignition lock
cylinder and turn it to the RUN position to drive the
vehicle.
Your vehicle’s engine can be started two times using
the transmitter’s remote start feature.
If only one remote start procedure has been done, since
last driving the vehicle or resetting the remote start
system, the engine may be started again remotely
following the remote start procedure a second time.
If the remote start procedure is used again before the
rst ten minute time frame has ended, 10 minutes will be
added to the remaining minutes. The added
10 minutes are considered a second remote start.
