I am looking for a place to get an ignition key for a Ford Roadranger 9000 - semi truck. It's a 1979 and the key has been lost.

 

You have some choices , you could either take the door lock tumbler or the ign key tumbler to a locksmith and they should be able to make a key(s) for you. Another choice would be to have a locksmith come out and make a key right there. They can remove the tumbler assy and read the code from the tumblers and cut a key that quickly.
