Replacing the Door Lock Actuator on a 1st Generation Prius (2002)

Posted by Russell Wright on May 25, 2012

This is how I replaced the door lock actuator on my 2002 Prius.  I took lots of pictures, so I hope this helps others. 

I purchased the door lock actuator from a Toyota dealer on line for about $85 + $12 shipping, so it was < $100.  Some folks have actually split the old actuator apart and replace the electric motor inside. 

Start by removing the door panel.  This is not hard, but it can be tricky. 

First, push in the center pin of the retainer on the outside edge of the door panel.  This will allow you to easily remove the fastener.

This is actually a picture of me installing the fastener, so you can see the pin is pulled out for installation.  However, to remove it you simply push it in and it allows the fastener to be removed.

Here’s a blurry picture of the final installation.

image

Remove the trim piece in the corner of the window by simply pulling it off.  You can see the location of the fasteners in the photos.

image

Notice there is a clip at the bottom (hard to see).

image

There should be a little clip that can easily be removed from under the cover.

image

Open the screw cover in the door opening latch handle area.

image

Remove the screw.

image

Notice that pull handle trim has a catch that slides into the plastic piece mounted to the door.  It also has “ears” that clip it in place.  This can be somewhat difficult to remove.  If you move the door panel and/or the trim towards the rear of the car, you should be able to slide it out of its latches and hook receptacle.

Remove the screw in the door grab handle recess.

image

You should be able to remove the entire switch assembly. 

image

Note the fastener on the front of the switch assembly.  This should pull straight up.

image

 

Now you can start unclipping the door panel.  Note that I used my hands and some plastic pry tools…you don’t want to scratch things up. 

image

Note the location of the clips.

Hopefully you can lift the door panel up and off the door by this point.  I had some difficulty with the door pull handle trim, but be patient and don’t break it!

Now remove the metal bracket.

 

 

image

You should be able to peel the plastic away and expose the cover.  Remove three screws.

image

image

Remove the cables from the clip.

image

Now we’re going to remove the entire latch assembly from inside the door with the lock actuator attached.

There are actuator two rods that have plastic clips.  You simply push up on the plastic clip to unlock it from the rod and then you can remove the rod from its hole.

image

Remove the torx fasteners that hold the door latch in place.

image

image

Remove the bracket bolt.

image

If you remove these nuts, you can swing the window rail track out of the way so the latch and actuator assembly can easily be removed.

image

image

image

As you remove the latch assembly, you should be able to unclip the electrical connector from the actuator.  Greasy and sweaty…

image

image

Now you can remove it from the top hole.

image

image

image

Remove the plastic cover by removing this screw.

image

Pull the cover off exposing cables

image

Remove the two attaching screws.

image

You should now be able to remove the cable and the ball/socket lever.  Note how it fits together while you are removing it.  It’s pretty simple, but make sure you get everything oriented the correct way when installing.

image

Old and new.

image

image

Now see if you can do it all backwards to install it.

Testing, 1…2…3.
