I baught the truck used and i dont think it even came with the original key. i know this feature is optional and not all vehicles have them How do i find out mine has a keyless entry reciever? Its a 2004 dodge ram 1500 Laramie this truck is loaded. it has a 6 cd changer to heated leather seats. so im pretty sure at some point someone had a remote to get in the truck? So how do i find out it has a keyless entry reciever? and if it does i can just buy a remote online and program it right???
