Replying to: saudiboy (Feb 12, 2008 7:25 pm) I know the symptoms are not the same, but the cure is similar... I posted some info for the driver's door lock motor/mechanism on the main RX300 forum archive, I think it was message 8925 and 8926. link title   Also, try searching "door lock motor" in the main forum. There were messages posted before we had all these extra sub-forums.   The RX300 uses a combination door latch, switch & solenoid/motor mounted to the latch. The mechanical key lock is separate, as I remember. Does the key turn, but doesn't move the lock? You may have a problem where it connects, and not the motor/latch/switch. But with the door panel removed, you will be able to check it out and replace the faulty component.   I hope this info helps!

Thanks.   I must have been turning the key the wrong way (I don't think I've ever used the key before). The key will unlock the front passenger door. It's just the remote that will not open or lock the door. Replies to this message: zedro (Jul 10, 2008 7:03 am) la4mead (Jul 10, 2008 7:21 am)

Replying to: saudiboy (Feb 14, 2008 10:56 am) I am having the exact same problem with my driver side door. It is a 2003 RX300.   If I find out how to fix it, I'll post back. If you've solved the problem by now though, please let me know.   thanks. Replies to this message: la4mead (Jul 10, 2008 7:21 am)

Replying to: zedro (Jul 10, 2008 7:03 am) This is a common issue we found, especially in RX300's that sit a long time, have a slightly low battery, or sit in the hot sun (100 degrees+).   Try searching in the RX300 forum. I think it was message 8925 where I put a detailed account of how I removed the door panel and replaced the motor/switch/lock combo. It's not for the mechanically challenged , but if you're a DIY it can be done in a few hours, saving lots of expense at the dealer.   I wonder if this link to get you there works link title   If not just enter "door lock motor" in the search. There's lots of info there.   Mine has been fine ever since. But I noticed my right rear lock gets sluggish when the car sits a long time (I normally use my motorcycle now) or it's been sitting in the sun on a really hot day , otherwise it's OK. So pretty soon I will pull the panel and lube the motor or replace it too.
