Programming Remotes from 1997 to 2004 Lesabre

1997 to 1999 Buick Lesabres


Important
Before entering the programming mode, verify possession of all the transmitters you will be using on the vehicle. Once you program the transmitter, the memory erases. The other transmitters will not be functional until you program the transmitters again. You may program up to 4 transmitters.

Perform the following procedure when adding new transmitters or replacing failed transmitters:

1 Turn the ignition switch OFF.
2 Use a fused jumper wire in order to jumper the DLC terminal 8 (BLK/WHT) to terminal 4 (BLK).
3 Close all of the doors.
4 Turn the ignition switch ON. The doors will cycle to lock.
5 Press and hold the LOCK button and the UNLOCK button on one transmitter. After a 30 second delay the doors will lock and unlock.

Important
Do not turn the ignition OFF or the first transmitter will become inoperative.

6 In order to program extra transmitters, repeat step 5.
Disconnect the fused jumper wire from the DLC.
