My door key lock doesn't lock/unlock the car. Anyone experience this? All locks work just not from the key slot.

Your door key lock system is attached to the actuator in the bottom corner of the unit. The key system fits into a round white plastic connector with a slot. This connector rotates and locks/unlocks the actuator.
My money is that the white plastic connector has broken.

Is that piece repairable or do I have to buy a whole unit?

VR4 is probably correct but I got to ask, does the key turn at all? There is a possibility that the rod that connects the lock actuator to the door handle has popped out of the hole in the door handle. It's supposed to be held in placed by a small plastic latch. I would open the door panel and take a look inside to see. You can see what its supposed to look like if you view the bottom of the three pictures from this post:

In this photo the plastic clip has been disconnected from the rod (the view is looking up toward the door handle)...

Yes the key turns, I found out the hard way that it didn't work after my battery died. Had to call a locksmith to get in. I pulled the panel to look but didn't have the torx bit to remove the black cover that holds the lock and door cable. I pulled the rubber grommet on the edge of the door. Didn't see anything attached to the back of the assembly.

I just noticed from watching videos that the key hole is on the drivers door. On my car it's on the passenger side, (could this be why it's not working?

Unfortunately, this is a frequently asked question on this thread. It's been over three years since the OP logged into the site. However, if one would take the time to read through the whole thread there is some valuable information there.

If you go here, you will be able to see what text was posted in the linked article but you will not be able to view any pictures.

If you go here, you will be able to see another explanation on how to perform the repair. Good luck and let us know how it works for you...

I replaced FR and RR door actuators this weekend. This was my first time disassembling a door on any car. I took my time and followed the instructions from mark levinson thread and this thread, and some youtube videos on how door handles work. FR door was done in about 3-4 hrs. I had to disassemble everything second time and redo the lock cable because first time, I did not leave enough slack at actuator (too much tension in the lock). From that experience, RR door was done in 90 mins. The actuators from amazon are not louder than driver side doors. Happy that I had to only spend about $30.00 all-in including zip ties. Thank you everyone for the tips and photos. Especially post# 9450992 by airchomper. One think I did not have to do was remove the door handle screw hidden under the black cover.

Hello - Newbie here with a 2004 LS430 in Toronto. My passenger rear door will not unlock due to the actuator issue. How do I open the door from the outside? Can we use the key to manually open doors other than the driver's door?

Apologies to reference an old thread but this is on the Sticky and I need to see a tutorial on how to do this. The left front door lock actuator is gone. I replaced the right one by the dealer and I would like to replace this one myself.

Thanks,
Ather

Ather I bought the motor then took it to a body shop they did the job in less then 1 hour charge me $50.00. Would not have it any other way. The only concern they had was not being responsible for cracking the case.

Ok thanks lexman52. Will try that.

Link appears to have been hijacked - leads to what looks to me like an advertising site. How can I get to the excellent video and write up to which this posting refers?

Thanks for the info. Are you able to re-post the instructions on a revised link? The one above is no longer valid.

Thx.
