Is it possible to get a vehicle without a key fob or remote and program one to it?

I'm curious because I'm unsure. Is it possible of I have a 2003 Ford Ranger that has 2 keys only to be programmed and have a key fob or remote to lock and unlock the truck? Is it possible to get a remote that locks and unlocks the truck like most new vehicles have?

No because there has to be receiver in truck to get signal when you press remote

Bull dog used to make on for vehicles with electric locks.
