This is most likely your problem. What brand alarm do you have? If it's a CODE-ALARM then it's probably the cause. I don't know why Ford chooses to use this brand... they suck!

 

It's the KARR security alarm system.

BTW try to avoid Power Ford in Tustin, Ca. I still havent gotten anyone to help me out after two days.... If I treated my customers this way at my work, I'd never get any return business...

Ill keep ya'll posted incase anyone else has this problem.
