Toyota Corolla Keys

Detach Key Fob

Flathead Screwdriver

This automotive "how-to" guide was specifically written to assist owners of the 2003 to 2008 Toyota Corolla in replacing the CR2032 3V coin battery in the key fob remote control.

Owners of other Toyota vehicles such as the Camry, 4Runner, Matrix, Yaris, Prius, Venza, Avalon, FJ Cruiser, Sienna, RAV4, Highlander, Sequoia, Tacoma and Tundra equipped with similar keyless entry systems may also find this guide to be helpful.

The only tool needed to complete this battery change is a small flathead screwdriver. A small coin or butter knife may also work if you don't have a screwdriver handy.

A replacement CR 2032 3V coin or "watch" battery can be purchased at a variety of stores such as CVS, Radio Shack, or Wal-Mart. I prefer to buy coin batteries on eBay where a 5 pack of CR2032 cells can be bought for $0.99.

Halves Popped Apart

Key Fob Opened

Pry Out CR2032 Battery

To pop open a Toyota key fob remote control, locate the small notch or cutout area at the top edge of the unit above the "Lock" button. Insert the small flathead screwdriver into the recessed slot and turn the screwdriver to separate the top and bottom halves.

5 Key Fob Parts

When I popped open the Toyota key fob, the buttons went flying across my desk. The battery is located on the underside of the rubber wrapped remote control unit. To remove the battery, gently pry it out with the small flathead screwdriver.

2 Buttons On Remote

Top Cover In Place

Two Halves

Push in a new CR2032 battery with the top "+" side facing towards you. Then turn over the remote unit, place the "Lock" and "Unlock" buttons on top and cover them with the top of the key fob remote. Turn the unit over again and place the bottom of the remote on top with the red "Panic" button facing up. Then snap together the two halves and re-attach the key ring.

Halves Joined

Snap Back Together
