I am not able to unlock the driver side door with the key, or manually.

What is your question?

It started a few months ago, when using my key to unlock the drivers side door, I would have to gently work the key back and forth until the latch popped. Tonight the lock failed, I am not able to unlock the door by using the key or by manually lifting up the lock mechanism. I am crawling through the passenger side door. The other door locks work by manual, the passenger side door opens with the key.
