yellowblue 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. 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. 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. 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. 2-10
