Just recently was blessed with an 09 RX350

The driver side door is the only door that will lock and unlock.
The other 3 doors will only LOCK using the fob or interior switch... They have to be manually unlocked.

It's weird that's the drivers side is the only one that works.
Any help is appreciated.

Ok. I hate to ask this, but I want to help you out. You do know that you have to press the unlock button on the key fob 2 times quickly to unlock the other 3 doors right? One press will only do the drivers door. I would also open the back 2 doors and check to make sure the child safety lock isn't on. This will allow the doors to lock, but not unlock. If you have confirmed this, I would say you have door lock actuators going bad on the other 3 doors.

Just pulled over to try this... Neither option worked...
Child lock is confirmed off...

If neither of these was the issue I bet your doorlock actuators are starting to go out. If you let them keep going, they might even stop locking the door as well. You would have to manually lock and unlock the other 3 doors.

@DOPEPICS, congrats on the RX.

I agree with 2GSKaizen, that is sounds like the actuators are going out. There is a slight chance that it could be a wiring issue (highly unlikely actually), but I would start with the actuators and go from there.

Since you recently bought this vehicle, it could be the previous owner had the dealership do the personalized settings to only unlock the driver door (requires techstream computer). It would also be very strange for all three doors to have bad actuators. If it were my car I would have Lexus check it out. The Lexus service manual has other things to check:

Going to pickup a passenger door lock actuator and see if it remedies the issue....

Hope the actuator works for you. Let us know if it solves the problem.

I doubt it is the actuator...It seems strange that all three of the passenger doors would be bad at the same time. The Passenger door locks are all wired separately from the drivers door, so I would guess it is most likely a wiring issue or a computer issue. I would go to Lexus and pay the 60 bucks for them to diagnose the problem.

I'm kinda having the same issue. My drivers door will only unlock with remote. Front passenger is good but both rears don't unlock or lock with remote... 04 GS430

Never knew I could go to the dealer...and get it diagnosed for so cheap ...def going to try that...
