I currently have a 2012 Ramm 1500 Big Horn 5.7 Hemi...recently out of no where the anti theft alarm went off for no reason and i cannot get it to turn off...the key fob refuses to work even using the emergency key also wont shut it off...also the truck will still turn on and run but the alarm still keeps going off only way to get it to stop is had to disconnect the battery so now im stuck if anyone knows what is going on please help

 

Is it possible that the emergency button on your key fob is stuck?

 

Since the truck will start and run, that does sound like the Panic feature. I think Sottis is on the correct path. You may try removing the battery from your fob and see if the alarm stops triggering then.

Of course this assumes that it's a factory installed alarm system and not aftermarket.
