Hi
It sounds like the drivers door central locking motor has failed as in VW's this is the master lock that powers the rest of the locks
Hope this helps Nick

Open the doors and lubricate lock and latch machanism with wd40 or similiar spray lubricant while working the latch and manual lock and then working the key

YOU MUST HAVE MASTER KEY:
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.
7. Close drivers door.

The relay or switch may be shorting, check other door lock controls for correct function, this will rule out relay and isolate the switch or rule out master switch and isolate relay.

Hi!!
I believe your alarm is in the PASSIVE MODE, here is how it works.

PASSIVE MODE Setting (Arming) Anti-Theft System The system will automatically set 30 seconds after following methods are performed: Remove ignition key from ignition switch. Exit vehicle, and close all doors. After performing this, anti-theft indicator on left side of instrument panel will light continuously for about 30 seconds. After 30 seconds, anti-theft indicator will blink once per second. When system is set, doors cannot be locked or unlocked using door lock control switch.
CANCELING THE ALARM AND REPROGRAMING MAY SOLVE YOUR PROBLEM.
Canceling Anti-Theft System Setting (No Alarm) When system is set (armed), but alarm is not sounding, use one of following methods to cancel system setting:

• Unlock left or right front door using key.
• Unlock all doors using remote keyless entry system.
• Insert key in ignition switch and turn to ON position (this is operative only when anti-theft system has not been triggered).

HERE IS HOW TO REPROGRAM THE ALARM IN CASE YOU NEED TO RESET IT.
PROGRAMMING
PASSIVE MODE NOTE:Initial mode is passive mode off. If there is a different signal in middle of programming, signal is invalid.

• Close and open driver door 2 times.
• Lock and unlock driver door lock knob.
• After performing this, system should start force lock after 2 seconds. Passive mode should now be off.

Good Luck!! A 4 THUMBS UP rating would be greatly appreciated for this solution. Thank you for using FixYa!!

The trunk lock is incorporated in the central locking system. This means that you can either lock or unlock the trunk by means of either of the front doors. You can also operate the trunk lock directly with the master key even if the vehicle is centrally locked.

Are you sure it is the Master Key? Try the key in the glove box lock. The power door locks should unlock the trunk for you turn the key if it is right over to the right turn it right over to the left . you turn the key to far right to stop the boot been opened when the doors are not closed.

Keep us updated.

I have the same problem kinda. Lost my master key and sent my ecu off with a home made 2 button key to program immobiliser. This key works to start the engin and drive but I cannot get the key to program with the alarm and locking system. You can try the following steps as may work for you.

I can get my car into programming mode after step 1 but step 2 does not work for me. The locks do not go off at all, not once or twice. Battery in remote key is fine as LCD lights red.

Can anyone help please?

The key you are using might be a valet key. Check to see if you can lock your glove box. If you can lock and unlock your glove box with the key then there is something wrong with your trunk lock. If the key does not work in the glove box, then you will need to order a master key from a toyota dealer.

My van is similar to your situation. I had the car alarm company who installed alarm reinstall a sensor and it worked for awhile..I have to get it done again or change whole alarm system/auto door locks altogether (update).. Good luck..
