I just got a used 2005 Ford F150 Supercab with 44k miles on it. I have had it for a few days and whenever I locked it, it would not beep. If I pressed the button twice, quickly, an alarm would go off (weird). Last night I went to the grocery store and got out of my truck. I didnt think I pressed anything, but the alarm went off. I pressed lock, then unlock, then the same and nothing happened. I turned on the truck and nothing happened. Finally I pressed unlock again and it went off. Now, whenever I unlock it and lock it, it beeps. Just one beep. If I quickly press lock twice, an alarm still goes off. Why is this? It is very troublesome.

 

sould like you need to visit the dealer if this is a ford factory alarm. I'd probably just yank that junk out and get a aftermarket alarm prewired from from Travis at www.kcautosound.com

 

Anybody have any ideas? I was just looking through the owner's booklet and binder and i found something that I don't think came in there from factory. It is an owner's guide on a ProLine C-5+ Vehicle Security System. I do not have the remote that is pictured on the front. Could the person that owned my truck before me have programmed this key, and now my key doesn't work right? A thought. Hope this helps you get an idea of what is going on. Please help me. Thanks.

 

I believe, now, that the alarm system is aftermarket.

 

Sorry mate, I can't seem to find any company making an alarm by the name of proline. Look under the dash and see if you can find a gigantic mess of wires crammed up in there. Normally it's fairly well organized under the dash so you can easily tell if a after market alarm is installed.

 

I am certain there is an aftermarket alarm installed. It is made by Omega. I am not sure if it is called proline or not. The factory alarm works fine, the Omega is intererring with it. I would love both, but I need the Omega one to stop beeping so much and for the alarm to stop going off. Any Suggestions?
