My daughter manually locked my passenger door and now my rear door locks are not working. The buttons are stuck in the unlock position and I cannot move them manually or with the unlock buttons or my aftermarket remote start fob.

I think you used the word "button" in two different contexts: for he manual lock actuators and the electric switches for lock/unlock. I don't mean to be picky, but it is a bit confusing/ambiguous.

Do I understand correctly, she manually locked the front passenger door, and now both rear door locks are stuck in the "unlock" position; the rear doors cannot be locked either manually or with any of the switches?

I used the term incorrectly. There is a round pin to activate the rear door locks manually,and a rocker switch that operates them electronically. Neither work. The rear door pins are frozen in the up position and I cannot lock the rear doors. The two front doors operate correctly.

Did this start after she manually locked the front door?

Yes,other than that they worked just. Everything I read tells me to replace the actuators but I am thinking something else is not right because it started then and both of them failed at once. Not normal but possible

I agree, it is not likely both rear actuators, or any mechanical parts, failed at the same time and because a front door lock was manually actuated. If you can identify the fuse for the door locks, I would pull that and see if all locks will work manually. I think we are going to need somebody to post an electrical schematic of this locking system.

In an effort to troubleshoot this,I disconnected the battery for 5 minutes but that did not help. Are you thinking its an electrical fault ?

Did you try operating the locks manually while the battery was disconnected (engine not running, too)? Yes, I think it is most likely an electrical problem.

Do you have your owner's manual for the car? Review Page 80 and see if the doors behave as described. It may help diagnose what's going on.

What sticks out like a sore thumb is "....aftermarket remote start fob...." Did you program the fob or was it provided when you took possession of the car? It might be that the fob needs to be re-programmed.

Yes, still no movement

No owners manual and remote was installed by an installer and has worked perfectly until she did the lock thing.

Sometimes, people have a right side bulb go out (headlight, brake light, etc) but they don't notice for weeks. Then the Left side bulb goes out, they notice, and think... both bulbs would not fail at the same time, SO... the bulbs are OK, it must be the fuse. AND the fuse is OK, and diagnosis proceeds into a rabbit hole. JUST SAYIN'.

Oh,I agree. I think the next step is to have it scanned and go from there

Looks like the lock knob/rod is mechanically connected to the latch. So...if it won't move, either the latch is jammed (which would also prevent actuator movement), or the actuator is jammed (which would prevent latch/knob/rod movement). Long shot questions...do the interior and exterior opener handles work PERFECTLY (not sloppy)? Do the child proof safety switches work PERFECTLY?
