ACE Door Lock

[cgeace29.3]

I have a 2016 Thor ACE 29.3. The door lock won't let me insert the key, almost like something is broke in the key hole. I can lock it from the inside with the thumb lever.

The dead bolt lock works fine.

I sprayed PB Blaster in the key hole no result.

Do I replace the lock? Where would I get a new lock?

Thanks

You might be using the wrong key mine has two one for each hole
