im a new member and i recently bought a 2012 Dodge Ram 1500 Express 2WD and i have viewed other threads about the remote start but i have the key fob that has the panic, unlock and lock buttons only. nothing on the fob indicates the truck having the capability for remote start ...... but it has it!! didn't know if this has been talked about or not but i figured since winter is coming i would be nice to share. i found out how because i was locking my truck as i was going to work (being obnoxious) but i was about 45 feet away when i heard my truck start. my first thought was WTF who is stealing my truck so i ran back to it and saw that i had started it with my key fob. the secret was lock the door (with the horn chime) 3 times and on the third hold down the lock button and waaalaaah. if this has been discussed already my apologizes. but if not!! i hope it works for you!!!
