The …striker… is the “pin” attached to the B pillar. It does not move.
The …latch… is attached to the door. The portion of the latch that engages with the striker is the part that moves.
I understand Riley’s …latch… mechanism moves. I was not talking about latch movement.
Reilly said his …key… would not turn.
I just inspected 2511. It does not matter what position the latch is in; a correct key will always turn.
His latch mechanism may well need adjustment.
Also, after 50 years, his key and lock cylinder may be mis-matched.
