The remote locking feature works in all respects except the chirp when locking and the panic alarm doesn't set off the horns. The lights flash as expected and the locks activate as designed but no chirp. Both horns work when using the horn switch and fuses are also OK. There's nothing in the owners manual about programming, as later models have, so I'm kind of in the dark. The chirp has worked since 99 and only stopped just recently. I put a new battery in the fob about 3 months ago but it still worked, then stopped chirping a few weeks ago. Any ideas?
