One of my doors on my 86 has an issue with the door key. About half the time, turning the key moves the lock mechanism almost enough to unlock the door. When this happens, the pop up pops up but the door won't open from the outside. Opening the door with the inside handle fully unlocks the door and the outside handle works.
The rest of the time, it operates normally and unlocks from the outside.
When it works normally, I can see the pop up looks like it cams past maximum and drops a little. When it doesn't operate normally, it looks like the pop up almost reaches maximum height but doesn't quite go up all way. The key feels the same and the amount it turns doesn't seem to differ whether the lock unlocks or not.
Any thoughts on what's wrong before I take it apart?
