Door won't open from outside

They probably locked your keys in the car & had to fish the door lock with a slim jim. They probably knocked one of the linkages off. Mechanics lock the keys in the doors all the time.

same thing happened on my 1996 toyota camry, picked it up from the shop and now the driver's side door lock and handle doesn't work. do i need to go to a locksmith to fix it?

If 4 Runner back lift gate wont open try this..Push firmly on the license plate..at the same time attempt to open the lift gate by squeezing the lift gate handle..If you hear the mechanism working release the handle and the pressure on the plate..When you hear the mechanism a second time attempt to open the door by squeezing the lift gate handle with no pressure on the plate..I did this sequnce several times and got it to open...Once open pop the cover of the lock mechanism and liberally spray BLASTER INTO THE MECHANISM..Let it work for about 20 minutes repeat...shut door..try again..it may be a bit fussy, but keep working that mechanism and it will free up..once its free spray WD 40 in that mechanism and in the locking mechanism as well That whole door thing drove me nuts until I figured what worked for me..GOOOOOD LUCK..
