Need help fixing door lock

Could be handle issues? What supplier? Did you flip lock 180* to see if handle will work?
Hi 4spdragtop, thanks for the response.
The handle works fine, so the door opens and closes okay, it just will not lock either manually or with the key. I checked which side the stiff wire connector comes down around the handle connector and tried both sides to make sure nothing is binding. I could not get the key insert to install with the channel down, which is the direction I thought I remembered it coming out, it would only go in with it up. I will compare which way the key goes in on the passenger side, and that should tell me which way it does go in for sure. I did vinyl wrap the car and the vinyl goes into the opening. I'll check and see if that is enough of a difference to prevent it from going in the other way, maybe that's it.
