WARNING: This page is about a different car, the 2002 Pontiac Sunfire, 2002 Chevrolet Cavalier, 2001 Pontiac Sunfire, and 2001 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Re-synchronizing may be necessary if remote battery is replaced or remote is used out of range too many times.
To re-synchronize system, press and hold both LOCK and UNLOCK buttons on Remote Keyless Entry (RKE) transmitter for at least 10 seconds. Door locks should cycle to confirm synchronization. Check RKE transmitter operation.
