Ok I've had this 95 F150 (truck in my gallery & sig) for a little over a year now and I have somehow managed to set the factory anti-theft alarm off 5 times and it's getting to be rather annoying. I think what I'm doing is when I pull my keys out of my pocket I am accidentally hitting the panic button and it's triggering it, but the other day I had the keys in my hand and I didn't use the keyless entry and I used the key in the door and unlocked it and opened the door then it goes off, so I don't see how I could have hit the panic button that time. I was just reading in the owners manual and it says that it's an option installed at the dealer and from the way it reads it's an add-on and is seperate than the keyless entry.

 

Take it to a local Stereo/alarm shop. They should be able to take it off
around $30.
If you unhook it yourself the truck may not start because of alarms ignion kill

If you know what wires to look for at ing switch, you may be able to remove it yourself.
