2013 RAV4 Key Fob
Notch On Bottom Left Corner
Insert Flathead Screwdriver
This automotive maintenance tutorial was specifically written to assist owners of the fourth generation (2013, 2014, 2015, 2016 and possibly also the refreshed 2017 model year) Toyota RAV4 in changing the battery in the key fob remote control for the keyless entry system.

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

A replacement coin cell (A.K.A. "button" or "watch") battery is part number CR2016 which is available from various manufacturers such as Panasonic, GE, Sony, Duracell, Maxell and Energizer.

The only tool needed to access and change the battery is a small flat head screwdriver.

Back Cover Removed
Remove Remote Unit
Pry Apart Remote Unit
Locate the small notch on the bottom left corner of the key fob.

Insert a small flathead screwdriver in to the notch and gently pry apart the two halves of the fob.

If necessary, you may also use a coin, butter knife or a nail file.

Pull the remote control unit out of the fob housing.

Carefully pry off the black plastic rear cover on the remote control unit with the small flathead screwdriver.

Push Out Old Battery
Panasonic CR2016 3V
Gently push the old battery out of the socket with your fingernail or carefully use the small flathead screwdriver.

If you use the screwdriver, try to avoid scratching the green plastic circuit board or bending the metal electrical contacts.

The OEM battery in the fob for this 2013 RAV4 was a Panasonic CR2016 3 volt coin cell.
