Driver door wont unlock using remote or power switches, starts to but then seems like it is locked

Here are the codes you posted along with the possible issues that may have caused each code to be triggered. It's possible the circuit these switches share has a problem that needs to be diagnosed.

It could well be a problem with the wiring or a problem with the connections between the switches and the Multiplex Control Unit, or possibly with the Multiplex Control Unit itself.

Does it work when you use the switch inside on the drivers door. Lock and unlock? If it does not then there is a problem with the electric lock motor inside the door. It will have to be changed. If the lock works with the switch inside the door, you have a problem with the remote actuator system that powers the drivers door lock. I hope this helps

Few Toyota models came equipped with remote door locks before 2008 - surprisingly!

Your car may not have the radio receiver to work with door locks. In that case, you need the radio and some wireing to pair with your remotes.

The locks on your vehicle are electronically controlled by the BCM - body control module . The driver an passenger door switche's are input's to the BCM . Do you know anything about automotive electronic's ? anti theft alarm remote, could this be part of the problem , No it's just a key less entry remote , nothing to do with the anti-theft .
Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• IBCM (PWR) 15-amp fuse

Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch Lock or Unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation
• An automatic door unlock actuation
• A last door closed locking (LDCL) actuation

Driver and Passenger Door Unlock Operation w/o Keyless Entry
When the body control module (BCM) detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the driver passenger door lock actuators transition to the Unlock position.

Your best bet , take your vehicle to a qualified repair shop ! Need special tool to diagnose .

Power Door Locks Inoperative

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the door lock switch parameter in the Doors data list.
Does the scan tool display Idle?
YES - Go to Step 4
NO - Go to Step 8
4
Activate the driver door lock switch to the LOCK and UNLOCK positions.
Does the scan tool display Idle?
YES - Go to Step 9
NO - Go to Step 5
5
Activate the front passenger door lock switch to the LOCK and UNLOCK positions.
Does the scan tool display Idle?
YES - Go to Step 9
NO - Go to Step 6
6
With a scan tool, observe the driver door lock actuator command and the passenger door lock actuator command parameters in the Doors data list.
Activate a door lock switch to the LOCK and UNLOCK positions.

1. Start with key out of ignition, drivers door is open all others closed and
drivers door is unlocked.
2. Insert key into the ignition (Do NOT Turn) and Pull key out.
3. Perform these steps within 40 seconds.
A. Using the power lock switch on the drivers door, perform 5 lock/unlock cycles
starting with lock. Use an even pace and try to go about one cycle per second.
(1Cycle = 1 lock and 1 unlock).
B. Close, then open drivers door.
4. Perform these steps within 40 seconds.
A. Using the power lock switch on the drivers door, perform 5 lock/unlock cycles
starting with lock. Use an even pace and try to go about one cycle per second.
(1Cycle = 1 lock and 1 unlock).
B. Insert the key in the ignition cylinder.
C. Turn the ignition to ON (Do NOT Start) then back to OFF.
D. Remove the key from the ignition.
5. Within 3 seconds the power door locks should cycle automatically indicating successful
entry into programming mode. Return to step 1 if the locks do not cycle at this point.
6. Perform these steps within 40 seconds.
A. Press the lock and unlock buttons on the remote simultaneously for 1 second.
B. Immediately after letting go of the lock and unlock buttons, press the lock button by
itself and hold for 2 seconds. Within 3 seconds, the door locks should cycle once
indicating successful programming. If the door locks do not cycle, or cycle twice.
repeat steps A and B in step 6 as your remote has not been accepted.
C. Repeat steps A and B in step 6 for each new remote.

If the remote key fob locks and unlocks the doors then the problem is more than likely the power lock switches, this is a common problem on the Venture Van.

Try reporgraming it
