Hello,
I have a 2004 RX330. All of a sudden, my passenger door does not lock when I use the remote locking key. All doors lock except for the passenger door. Anyone experienced the same issue? Is there an easy way to fix this?

 

Seems like a common old age problem. Plenty of reading, just do a search on "door lock actuators"

Does it unlock? Try manually locking it and click on the button for unlock....does it?

If not, then bad actuator, could be just a pinched wiring...but would require for you to take down the door panel. Not a big deal for a DIY.

 

In most cases if you lubricated your doors and closures these problems will never show up TRY GiG-A-LOO
