Owners of other Toyota, Lexus and Scion vehicles such as the Corolla, Camry, Matrix, Yaris, Tacoma, Prius, Tundra, Sienna, FJ Cruiser, Venza, Highlander, Avalon, 4Runner, Land Cruiser, Sequoia, IS 250, ES 350, GS 350, RX 350, FR-S, iQ, tC, xB, and xD may also find these DIY instructions to be helpful.

The tools needed include a small flathead screwdriver, a regular flathead screwdriver, and a Phillips head screwdriver. To replace the speaker, you'll need an electric drill with some drill bits. To fix a sticky door lock, you'll need some a can of spray lubricant.

I'd recommend using Silicone Spray Lubricant.

The first screw is located behind the door opener handle. Pry out the small rectangular plastic screw cover using the small flathead screwdriver. Remove the single screw with a Phillips head screwdriver and set it aside in a safe place.

Next pry up the door lock and power window switch panel with the flathead screwdriver. Don't use excessive force to avoid damaging the plastic friction fasteners.

Remove the two Phillips head screws located on the arm rest.

Now you can move to the bottom edge of the door panel and pull out the pop rivets. The door panel is held in place by 8 plastic friction fasteners along the bottom and sides. Pull on each side until they are all popped out.

Set the door panel aside in a safe place.

I'd recommend purchasing new speakers from Crutchfield since they usually include any needed brackets or power connector adapters.

If you'd like to reduce road noise, make your car quieter and improve the sound from your speakers, I'd recommend installing some Dynamat Sound Deadener on the metal door frame.

To help solve the problem, I lubricated all the moving parts of the door lock/unlock mechanism that I could reach. It would be best to use a light lubricant such as silicone or white lithium grease. You could also try using WD-40 or PB Blaster all purpose petroleum based lube.

Spray a small amount of silicone lubricant in the key hole, on the lock/unlock lever by the door handle, and inside the door frame.

Then line up the plastic pop rivets on the rear of the panel with the corresponding holes in the door frame.

Replace the two Phillips head screws on the arm rest.

Push the power door lock and window connector back in to the socket at the rear of the switch panel.

Lower the arm rest panel and snap it in to place.

Be sure to check that the power window, power door lock, and door opener handle work properly.
