Programmable Horn Chirp
When you use the remote lock control transmitter to
lock the doors or use the delayed locking feature the
parking lamps will flash and the horn will chirp.
The programmable horn chirp can be disabled by
pressing and holding either of the door lock switches in
the unlock position for 10 seconds with the ignition ON
and all of the doors closed. When you hear the horn
chirp, programming is complete.
To reactivate the horn chirp feature, repeat the
above procedure.
Matching Transmitter(s) To Your Vehicle
Each remote lock control 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 dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
You can match your transmitter to as many
1999 General Motors vehicles as you own, as long as
they have the same remote lock control system.
Contact your dealer for assistance with this.
Battery Replacement
Under normal use, the battery in your remote lock
control transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
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.
