The locking system has failed, we replaced the batteries in the keyless remotes and the doors still don't lock or unlock, the only thing that occurs is the chirp of the car alarm. how do I get the remote keyless
Disconnect the battery from your car (negative cable only) overnight. Make sure you have your radio reset code before doing so.
Then reconnect after 10 hours, and make sure you have remote handy as alarm may go off. Then if that doesnt fix it, go to driver door, then insert master key, pull up on handle first all the way and hold it. Then turn the key slowly all the way so the doors unlock and continue turning the key. This will reset the central locking system as yours may have gotton stuck. then remove key let go of handle, open door and try to lock and unlock doors from switch inside car.
Then try remote. It should work, this is what the dealer will do and charge you about $350...if it doesnt work order a new remote b/c yours may have become damaged by liquid or dropping?
