Drivers side door lock

[CarDriver]

My front drivers side door lock will no longer open with the key. I did try the re-sync method but it did not work. I am afraid I burnt out something? Has anyone had to replace something in the door for that?

PS. When I open up the car from the drivers side, all the other locks pop up except the drivers door.

I will search my Bentley but if someone here has done it, it will be a big help with more info.

Thanks.

looks like it could be the central locking device. I may need to replace it unless some else knows of something different?
