Ok so, every once in a while (more often than I'd like) when I hit the lock button on my FOB after getting out of my car, the horn starts blaring as if I had hit the panic button or something. I thought maybe I was bumping the little red panic button at the bottom, so I ripped the f'n thing out of the FOB. It still happens. It happened once last night when I got home, and again today when I got to work. I have to hit the unlock button really fast, and then lock it again and everything's cool. Anyone had this problem?

thanks
