RX300 driver door won't unlock/lock with master key or keyless entry
I have a 2002 RX300. Just recently, the driver side door lock will not function with either the master key or wireless transmitter.
Is the problem the door lock actuator or something else?
Thanks

Are you saying that the master key won't physically unlock the lock, as well as the remote (on the same key) won't operate the lock electronically? That would be strange because the one shouldn't have anything to do with the other. Even if the remote won't unlock or lock the the actuator, the key should physically unlock and lock the door. Please elaborate.

The master key will not physically lock/unlock the driver's door. The key goes in the slot all the way, but will not even turn a fraction of the way in either direction. Right now, I am having to use the passenger door to gain entry.
Also, if I hit the auto lock button once inside the car, all of the doors will lock except for the driver door. I figured this was due to a faulty lock actuator.
Could a bad actuator be responsible for the master key not physically unlocking the door, or do you think it is the lock itself?

Up until yesterday, the electronic remote was the only way to unlock the driver's door. For the past 3 or 4 months, the master key would not physically unlock the door, but the keyless entry system worked fine. Now, neither works. It has me puzzled.

Have you tried to lock and unlock with the little "rocker locker" above the left inside door handle? If that works, it's likely the actual tumblers in the lock cylinder that are bad. That would be in addition to the lock actuator that seems to have gone bad now. Post whether that works or not.

I tried the master key in the driver's door yesterday and it worked fine for the first time in months. Tried it today and it wouldn't unlock. It is the strangest thing.

Adam, seems like a silly question but have you "lubed" the lock cylinder? I try never to ASSUME anything because the best assumptions are wrong about 50% of the time. I would lube it with some graphite and try inserting and removing it many times to make sure the tumblers (if THAT'S what that crazy key uses) are well lubed. Most of us seldom ever use our key in the lock because almost everything has remote locks and the tumblers get really dry, dirty and lazy.

No, I wouldn't use the white lube. Or WD-40 or oil. They collect dirt and the graphite won't because it's dry, but lubes very well. You should be able ti find it at an auto parts store and it should have a narrow snout, because that's mostly what it's used for, lubeing locks.
