Well, this would help the problem. It still wouldn't be the best solution, however. You can still unlock the door at strange places:


Not the best place to unlock a door...

This is a durastic improvement over the other having a 2x3 door, but still looks odd. Implementing a lockblock trigger would improve Link's ability to actually find the keyhole to put the key into even more.

And this wouldn't be the only situation in which the lockblock trigger would be useful. Which is why I made this thread.
