Well I get home tonight, and my factory alarm goes off on my 93 sc400 for no reason. Go outside turn it off, lock the doors, and it happens 2 more times. So now the doors are unlocked

I've read that it could be a phone fuse, which i wasn't able to locate under the hood and it's dark right now so can't check the kick panel right now. And also read it could be the knock from the cats, and also the courtesy light switches.

The only thing i've done recently is lower the car. My roomate came back home who has an rx300 (interference maybe) but I highly doubt that.

Anyone have any other ideas what it may be?

Thanks for any suggestions.

Mike
