Front passenger door lock

#1
Just got my car back from paint shop. The front passenger door lock is not working as it should. When the inerior door lock button is depressed and the door is shut whilst holding in the exterior door handle button the interior button pops up again (unlocks). The mechanism is all a bit stiff as well.

Any simple adjustment to fix this?

No simple ones. Most likely you've got wear & old lube in the outer push button gumming up the works. You can remove the button, disassemble it and relube but it's not a 5 minute job.
