Default '03 CTS Locks Engage/Unlock Every 30 Secs... HELP!

This problem started the other day out of nowhere. While driving, no problem. When I turn the car off, whether I lock the doors or not, after 30 secs or so the automatic locks will engage (if I lock it with remote or by hand) or (if unlocking) and will continue doing this EVERY 30 secs indefinately. I had to turn off the feature "lights flash/horn sounds" at "key out" and "on remote lock" because of this!

Also, what happens depends on which button I hit. If I hit the panic button, every 30 secs the alarm goes off. If I hit the lock button, the car attempts to lock every 30 secs or so. The same with unlocking... Very imbarrasing when people are around... Someone please HELP!

Wow, that's weird.
Could be a bad RIM or a bad ground or a bad antenna module.

I suggest taking it to caddy.
