So if I understand correctly, the keys go into the door locks, of which there are two, and the trunk lock, one, and they do not turn from the vertical position in the doors and do not turn the trunk lock, but they do all work in the ignition.

I assume also that you cannot lock your car, since the key will not turn the driver's side lock.

If it is the same with all of your identical keys, then I would conclude that the problem is with the locks. It is unlikely that all of the locks would stop working at the same time, on their own. Is it possible that someone put something into your lock cylinders to damage them?
