VW Key not working

after a battery replacement on a remote the remote will Lock the car, but not unlock it (it will unlock the tailgate).

Now the key and spare key will not turn in the driver’s door.

Has anyone else had this type of problem?

My key wouldn’t work in ignition of 91 Honda Civic, so it’s likely a different problem, because in my case it was the key itself. It was just plum worn out and dull at the edges. I had a copy cut and the copy works.
