Section 7 (Body Control Modules): Programming: Transmitter: Notes
WARNING: This page is about a different car, the 1999 Buick Regal and 1999 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
If transmitters are lost, new transmitters can be programmed to Remote Control Door Lock Receiver (RCDLR). A maximum of 4 transmitters may be programmed to vehicle at one time. When new transmitters are programmed to RCDLR, all previous transmitter information is erased. All transmitters must be programmed.
