Hi all, first post on this forum.

I have a 2005 F150 Lariat and whenever I use the key fob to lock or unlock the panic alarm sounds. I've tried the reprogramming dance several times - each time the fobs work great for maybe 15 minutes and then revert back to the panic alarm state. At this point it's getting really frustrating.

Using just the key to lock/unlock works just fine. Using the remote is the only thing that sets off the alarm. Any ideas?

 

Is it just a beep ... or constant alarm ? I thought I read somewhere that if you get a beep its an indication that the battery in fob is getting weak.

 

Panic alarm. Full on constant beeping.

 

Id put money on your fob needs a new battery. When was the last time it was done? Dying fob batteries cause some strange issues.
