My 1990 518i had the doors opened by a recovery service after the battery went flat. The current position is that the key in the driver's door activates the central locking, and successfully locks the other three doors, but not the drivers door.

On the other three doors the vertical pop-up lock things have free movement but on the drivers door it is stuck jammed in the upright position. The central locking doesn't move it and neither can pressure by hand.

I found the following web page and tried turning the lock to the far right but it hasn't changed anything. Any suggestions, please?
