Drive it around on some bumpy roads. maybe it will fall back into its bad habits. Seriously, drive it around. the road vibration might loosen up the mechanism and alleviate what is bound up. I had an Off Topic car, German brand that the passenger door would randomly not let you out. Once you tried the door from the inside the latch would get stuck in a half open/half closed position. Start car up, drive around the block, try door again, repeat. eventually I could get passenger out without crawling over center counsel and shifter. After a while I learned to carry a 5lb hammer and block of wood, when it would happen, get out, place block of wood over external door handle , beat on with hammer, open door.
