Hello everyone, just purchased a 1974 Tii. Try to lock it or unlock it but it does not work. Apologies in advance for the redundancy. The key turns better on the unlock position but not a full turn motion on the lock position. Regardless on the movement, the vertical rod does not move up or down. I have read a few threads and took a chance to remove the panel door. I removed the door handle, remove the cylinder inside the door handle, lubricate everything, put the mechanism back into the door handle, tried it before reinstalling into the door frame, the latch moved freely. When putting it back into the door, same thing, does not move as freely and does not lock or unlock. The metal part where the vertical rod hooks does not move at all. I tried to pull it up or down it does not budge. Isn't it supposed to move. I'm supposed to take out the latch mechanisms on the side of the door, I only removed the door handle.These are some pictures. Thank you.
