My nephew made a replacement piece out of aircraft aluminum in his machine shop garage. If this is indeed your problem, pm me.
I finally got around to opening up the lock to take a look.
First, this is NOT a lubrication issue. The springy part compresses and springs back perfectly fine. The issue is that the latch part that sticks out actually sticks out TOO FAR. Here is a photo:
Because there is a flat part (circled in Yellow) sticking out, it hits the door jam when closing the door and the springy part doesn't get a chance to compress to allow it to close. It should look more like this photos:
where the slanted part of the latch will be the first thing to hit the door jam and therefore it will compress that latch and allow the door to close (and then spring back open to latch the door).
I took the door latch apart. Here is what it looked like:
I could see that there was a little plastic piece kind of floating around in the innards (by the springy part). I was able to get it out and it looks like this:
DFord: It looks like what you have in the picture in your post.
Is this something that broke? Does anyone know where this piece is supposed to go? My guess is that when this piece is in place wherever it is supposed to be it prevents the springy part from extending out too far.
If this piece is broken and requires a completely new latch, I do think I see what might be another solution... In its "resting position" the latch guts inside the mechanism looks like this:
If I manually compress the latch that is sticking out to be at a better resting position (such that only the sloping part sticks out and then when the door closes it will compress and work correctly), the latch guts look like this:
If I cannot find the proper way to fix the lock/latch, I think I could probably glue a small metal block (~1/8th inch x 1/8th inch) on the latch in that space to prevent it from sliding out too far. Does that make sense?
Let me know if you have repaired such a lock and if that small piece I found floating around is something that is broken or just out of place.
