2002 rav4 doors won't unlock only lock

If the door wouldn't close how did you close it to lock it and have to exit out the passage side door? Anyway if the door is open like you said and it's locked you can easily access the locking mechanism without removing the side panel. It's on the side of the door, not the inside and not the outside, but the thin strip visible only when you open the door. There will be two metal pieces that clasp together. You can separate them manually, this will unlock the door.

I have this same issue,I'm told other kia's also have this issue. Friend of mmine says little pin/rod that goes from lock 2 handle needs adjusting,don't know.have body shop check it out 4 u or call kia.I'm sure they have heard of this problem.That's what i'm gonna do if I can get mine running,been down 4 about 2 wks. good luck

1) Key turns but dose not unlock door. This means that the rod that goes to the back of the lock has came off. This also means that is the reason door is not unlocking with the remote as it pops the lock rod inside the door which pushes the lock open.
2) Key does not turn lock at all but works passengers side door. This means that the locks has been changed in the door, but that doesn't sound like the problem as you say the remote doesn't open the drivers side door so more than likely the rod has came off the back of the lock

door in passenger side will not open in the front

Do the power windows work ? DDM - driver door module fuse 15 amp - location is the instrument panel fuse box , plus LT DR circuit breaker 25 amp. Circuit breakers rarely go bad . The power locks are controlled by electronic's .The passenger side has another power supply ,that's why they still work .
Door Lock System Components
The power door lock system consists of the following components:
• The driver door switch (DDS)
• The passenger door switch (PDS)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock/unlock relay (LBEC)
• The reversible door lock actuators in each of the doors and liftgate

The front power door lock switches are integral components of the driver door module (DDS) and passenger door module (PDS). The switches are 2 position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDS or PDS. The DDS or PDS monitors these inputs and sends a LAN message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock/unlock relay and also send a LAN message to the DDS and PDS to perform the appropriate function.
The modules which activate the power lock motors are:
• The DDS (driver door lock actuator)
• The PDS (passenger front door lock actuator)
• The BCM (both rear door lock actuators and cargo door/liftgate)
The DDS and PDS are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and endgate doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. The energized the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

It's possible you have broken wire or wires inside the flex boot from the body of the vehicle to the driver's door . This happens a lot .

Look at the other door and look on the front edge to see where the child safety lock switch and see if that is the problem with the other door. That has happened with mine several times. Someone will play with it leaving it on so it can't be opened.

Did you find a solution to this A's I have exactly the same problem

Your door latch assembly may be compromised. It could be rusted, the electric solenoid (if it has one) may be seized. Or the rods from the key are bent. Are you using th key in this door regularly? If not, the tumblers in the lock may be seized. Spray some WD-40 in the lock where the key goes, and jam the key in & out repeatedly, and retry. Remove the door panel & spray the interior of the latch, also. Hope this works for you; or, you are going to need new latches.
