Rear doors are stuck in locked position, there not electric; we cant open them

If it won't open from inside or outside. The power lock actuator is stuck in the lock position. The child safety lock is also activated

Call the dealer ask a mechanic how to open door they likely have a trick and they want you to buy the parts so ask for an exploded view of door and lock you might be able to fish the window and yank the lock bar

can you manually unlock it

Is your mother in laws body locked in it ?

use a round bar ( a screw driver ) and place it under the latch and pull the latch out as you press the button to unlock as if you were opening the door.

use a round bar under the lock tongue and pull it back as you press the button to open the latch

check the closing mechanism and see if it isnt locked down in the closed position, if it is stick your finger in there and pull it out like it would open while moving the door handle, if thats not the problem, see if there isnt a toy or something stuck in the tracks on the bottom or dirt and leaves on the top

sounds like you lached the door
use a screw driver or some such tool
lift the outer handle and slip your tool in the middle of the lock hole in the door flip the lach open wile holding handle up

It sounds to me ( correct me if I'm wrong ) like the door latch on the side vertical edge of the door is in the LOCKED POSITION. In order to unlock it perform the following. First electrically with the LOCK button UNLOCK the locks. Now with one hand hold the OUTSIDE DOOR HANDLE IN THE OPEN POSITION, while at the same time FLIPPING OPEN THE LATCH. All Done . Now you can close the door. Hope this helps

The problem is with the electric lock actuator, it will have to be replaced.
