Battery Replacement - Buick 2006 LaCrosse Owner's Manual

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.

To replace the battery in the remote keyless entry
transmitter, do the following:
1. Insert a flat object, with a thin edge, into the notch
located below the panic 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 one
three-volt, 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 inside the transmitter.
5. Test the operation of the transmitter with the vehicle.
