Door mech. froze....

Hello I have an 89 S-10 4x4 2 door blazer and the door lock mech. froze. I am able to get all of the rods off except the one that connects to the place where you put your key in anyone know how to get at it? It is really tight I can just touch it with my finger tip and do not want to break the rod off I figured I would ask here to see if anyone has any backyard tricks up there sleeves...

THanks in advance...
