Is it humanly possible to have an actual key lock installed on the passenger side of a Colorado? Can't get any answer from dealers...GM says Yes.. your thoughts?

I would love to have a door lock on the passenger side. I never checked to see if the truck had one because I have never seen a vehicle with out a door lock on both doors. With the optional remotes it is not a problem but thoes of us with no power locks it is a pain to not have a lock. If you get one please tell me how you did it so I can also have a passenger door lock.
