We finally found a 76 LC, got it home and am in the process of learning the truck and generally moving in! We are pretty stoked....anyway, the lock for the ambulance door only came with one key (I am attaching several pics). I went to a local locksmith who could not determine the blank he needed to make the copy. I am wondering what the best route is. Maybe buy the new OEM lockset that comes with several keys? Or try and find a blank? Any suggestions would be greatly appreciated. The number on the key I have is #4533 and is labelled TR on one side, and is labelled Toyota Motor Company on the other side along with the TEQ logo. Thanks! - Bob
