The driver's door to my Prius will only unlock with the key, or pressing the rocker button from inside the car. All other doors and rear hatch unlock with key FOB.

If you mean the fuel door... if it is not unlocking make sure the key is on and pull the fuel door button on the driver's side door. Button should be next to the rear hatch button. If it is not releasing check your fuses. If you need fast access remove the carpeted side panel inside of the rear hatch and you will find an emergency release.

Rear hatch is locked or unlocked with a key. (if equipped) • To open the rear hatch, insert the key into the lock, turn it to the unlock position and pull up the rear hatch by pressing the handle (DOOR). You can also lock/unlock the latch (but not release it) with the central door lock system. • If unlocked, the rear hatch can be opened by pressing the handle (DOOR) and pulling the hatch up. • To close the rear hatch, lower and push down the rear hatch firmly. Make sure that the rear hatch is securely latched.

Donald: Here are some comments on SubaruForester.org : "We just got a 2007 Subaru Forester> and we absolutely love it.

I was wondering if anybody out there has a solution to this small gripe:

The only way to open the rear hatch is to first unlock the driver's> side door, then hit the unlock all button, then walk back and open the rear hatch. It sure would have been nice if the rear hatch had a slot for the key, or there was a button on the remote you could press.

Anybody else have this gripe, and is there a solution?
---------
Two presses of "unlock" on the key fob unlocks all 5 doors.
--------------------------
If it has a key, try that.

My only suggestion is double-clicking the unlock button, while standing next to the rear hatch. I know that on my 2003, it's sometimes a matter of timing.
==================
I remember reading somewhere (can't recall where) that sometimes
if you are parked on uneven ground the rear hatch can be a problem
to open. If you are on uneven ground, try moving the Foz to a more
even place.

Since the driver's door gets the most use, and all circuits run through the master switch, check driver's door first and check the wiring at the hinge area for breaks.

No idea here its all this fancy electronic stuff ,i have a funny feeling that you may need a new door lock mechanism as they are full of electronic gismos with more chips than a spectrum computer

i am in england,and our cars have a 2 position lock,turn left then release OR turn right and release,one of these will allow the rear door to be open when then the rest of the car is open.

First, on the rear hatch, there is an actuator. On FX, when you close the trunk, it kind of **** the hatch closed all the way. When you press lock on the remote, this same actuator locks it as well.
Now,
1) when you unlock the car from the inside, go back there and press the button to open the hatch door manually, do you here any noises?
2) Close all doors, go back close to the hatch button and using the remote , lock the car and then unlock the car. you should hear a sound from the actuator locking and unlocking the lock on the rear hatch!

If you don't hear this, your actuator is inop.
Next step would be to check the fuses inside the car, on the left bottom driver side, and outside on the battery compartment.
It might be just a fuse.
If all fuses check ok, your actuator is most likely gone! Not ea expensive fix, just time consuming!

NOW, if you can hear the noises, then something is either broken inside the actuator or one of the cables is loose!
Hope that helps.
Also, what year and miles on your fx?

The lock is stuck in the "locked" position.
When you close the hatch, it is jamming the latch hook into the wrong area.

Manually open the hatch. Unlock the hatch (even tho the hatch is already open). there are two bolts holding the metal "loop", the loop has moved. Adjust the metal loop and close the hatch / lock it, etc.

No easy way to do this - you need to remove the inside door panel from inside the truck and manually release the lock. You didn't say where the wiring was burnt, but when the door is open test for power at the lock solenoid - if not there when unlock is pressed, inspect the wiring (particularly at the two rubber wire casings connecting the door to the frame). If it is there, the lock solenoid is stuck and may have to be replaced.

1) Unlock all doors from driver's door while it is open. The driver's door is the only door to remain open during this process! 2) Turn the key from OFF to RUN 8 times within 10 seconds, with the eighth turn ending in RUN. All the doors will lock and unlock if program is successful. 3) Turn key OFF and remove key from ignition. Within 20 seconds, press any button on the remote. (Press sliding door or rear hatch and it will open!) 4) If door locks do not respond, wait several seconds and press button again. If doors still fail to respond, try repeating steps (1-3).
