Question about door locks
When I use the key fob to unlock the doors, it works fine. I leave the drivers door open and In about 1 minute I can hear what sounds like the locks re-locking. At first, I thought it might be a bad door switch that is confusing the computer but when I looked at the door, i see no door switches anywhere. How does the RX300 know if the door is opened or closed? I know many cars will relock the doors if you dont open the door within a given time. But my door is open. It should recognize that.
Any ideas?

All the sensor and the lock motor are part of the door lock assembly (actuator) which is in the door jamb.

The door lock actuator will lock all the doors after a short period, even if the door is left open. Would I just replace the drivers door lock actuator? Or does this go deeper in the computer

I am only going by your statement .. that it RX 'locks all door' after a while. I have never timed it, but the only time it should happen is if you 'unlock' the doors and then DO NOT OPEN any door (including tail hatch), then then all doors lock them selves after a while. [This feature assures that the RX locks up when the owner accidentally hits the unlock and really meant to lock. If the intent was to unlock then within the period any door would have been opened].
When a door is open, and some one tries to lock .. you get a beep .. not sure it immediately unlocks.
If the key is in ignition then the remote lock is pressed, the door should unlock immediately.
If you RX behaves differently then a power cycle of the battery usually clears up things.
Hope the above helps.

Exactly. It operates differently and a battery disconnect did not help. So my question is, does the drivers door actuator have a sensor in it that should recognize the door is open or closed? Because my rx does not know the door has been opened.

Could be problem with the wiring too. Lexus has superior sheathing for wires [unlike BMW of the same years which had the trunk wire problems], but each time the door opens or closes the wires rub.

Yes. Set wires deal with lock and the another deals with the door ajar/closed. The U hook in the pillar moves mechanism to sense door ajar or closed.

I'm not sure I understand. Does the anchor bolt on the door frame move?
Okay I checked and the U bolt is not moveable. It must be in the lock mechanism. Is the left front lock mechanism the same on a 2002 as the 1999? I have a local source parting out his rx.
Is there a way to disable the self-locking feature? I don't have an owners manual handy.
Here is video of it:

Honda many years ago had a car icon with each door in the dash that would tell you which door is open ,,, apparently due to copyrights Toyota could not have it.
If you try to drive and as vehicle picks up speed ... 2mph? you will hear a soft ding.

My other toyota will relock all doors if you dont open the drivers door. But even then, all the doors would need to be closed. Im working off the premise the drivers door is the master for keyless entry.

Thats about all I can help. If you have a storage scope and service manual you can check if the right pulses at=re being generated from the rf receiver.
