For anyone with door lock issues. Front passenger door lock suddenly stopped working and couldn't open door from either inside or outside. Audio car install shop figured out it was rusted lock mechanism, got door open and fixed for under $200 only labor needed. Avoided having to cut interior panel off. Hope this helps for anyone with a similar issue.

 

Glad you got it fixed. Good to know for future reference. As for not cutting the interior panel off, that is not necessary as it comes off pretty easily.
