Small flat-head screwdriver
Icepick-like tool if available
Phillips screwdriver (preferably 2 sizes: large and small)
Duct tape

1.    First, start by opening the door. :) In case, for some reason you've never seen it before, this is what it looks like:

2.    On the inside of the door towards the front of the truck you will see a plastic center pin clip. To remove this clip, simply press in the center of the plastic clip with an ice-pick like tool or screwdriver. Remove the entire clip by carefully prying the outer ring with a tiny flat-head screwdriver.

To put it back in, push the center pin back through the outer ring so it sticks out the other way. Place the entire clip back in the hole and press in the center pin to lock it in place.

3.    At the back of the door towards the rear of the vehicle you will see another plastic center pin clip. It's smaller than the one above, but is removed the same way.

4.   Carefully pry up the armrest at the front, middle and back. If you get that much open and it won't come out cleanly look underneath it and use a flathead screwdriver to push the final one or two white plastic clips to get it out. There are potentially 6 or so plastic clips that are breakable so be careful when you do this.

5.   After you've removed the armrest you will see two screws which you need to remove.

6.   The next step is to remove the power window and door lock panel. Pry it up ONLY AT THE FRONT of it. There is one plastic/metal clip that will give and once you pop it up, slide it forwards toward the front of the truck to remove.

7.   Detach the two wiring harnesses to take the panel completely off. The wiring harnasses are different so you can't make a mistake when you try to plug them back in.

8.    Now remove the small screw holding in the door release handle. Using a Phillips screwdriver, take the screw out. It will be smaller than the previous two you had to remove.

9.   Door latch time. This is a little tricky, but if you're careful you won't break the tiny plastic pieces. The plastic door handle release is connected to a metal wire in the door by yet another plastic piece. Your goal is to remove the plastic door handle WITH the little plastic connecting piece, leaving the metal wire on its own.

At the bottom of the (in this picture it's green) plastic piece there is a little clip which holds it to the metal wire. Use a flat-head and pry it gently downwards so it can release from the metal wire and rotate it. Once it's not holding the metal wire via the little clip on the bottom, you can now slide the door handle and plastc piece upwards to detach it from the metal wire.

When you're finished, the door panel should look like this:

The removed plastic door handle should look like this. You can see in this picture that it is white instead of green. I had already pre-purchased two of these plastic clips from Toyota in preparation for replacing them (and just in case I broke them). So this what the new piece installed looks like:

10.   Ok, we're almost at the end now. On the bottom half of the door panel, it's held in by 7 plastic clips. You will need to grip the bottom of the door panel at each of these 7 spots and pull forcefully, but carefully. Once you have all the clips off, push the entire door panel upwards and it will come off.

You can see the spots where the 7 clips will be found here:

Door panel now completely removed:

11.   When we pulled off the passenger side door, there was an extra black plastic clip that is shown in the pictures below. Strange thing was that this was not present on the driver-side door. I get the feeling the doors panels had been taken off before and the original owner lost one. You can see below where the plastic clip goes both on the door and the door panel:

12.   If you need to remove or replace the plastic sheet (used to prevent water and dirt from collecting within your doors) be sure to remove the two grommets (shown in the picture below) first:

Also note that this is a good time to inspect the condition of the plastic sheet and make sure it's sealed properly all the way around. I like to be extra sure so you can see the start of my duct taping all around which I did on both front doors.

That is all! Installation is the reverse of removal.
