WARNING: This page is about a different car, the 1999 Pontiac Montana, 1999 Oldsmobile Silhouette, 1999 Chevrolet Venture, 1998 Oldsmobile Silhouette, and 1998 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

Press transmitter LOCK and UNLOCK buttons simultaneously for at least 7 seconds or until horn sounds if equipped with Content Theft Deterrent (CTD) system.

Each transmitter has a unique code that continually changes. After programming transmitter to vehicle, the RCDLR will update this code to match code programmed in transmitter. Transmitter may not communicate, or may become out of synchronization if one of the following conditions occur:

Transmitter is activated more than 256 times while out of range of vehicle.
Transmitter is immediately activated more than 16 times (while out of range) after transmitter battery replacement.
