Notch At Bottom Right |
Insert Flathead Screwdriver |
This
automotive maintenance tutorial was specifically written to assist
owners of the third generation (2011, 2012, 2013, 2014 and the
refreshed 2015 & 2016) Toyota Sienna minivan in changing the battery in
the keyless entry system's fob remote control. Owners of other Toyota vehicles with similar key fobs such as the Tacoma, Tundra, FJ Cruiser, Venza, Highlander, 4Runner, Sequoia, RAV4 and Land Cruiser, may also find these DIY instructions to be helpful. A replacement key fob battery is part number CR2032 from various manufacturers such as Panasonic, GE, Sony, Energizer, Maxell, Duracell, Enercell, and Philips. The only tool needed to replace the battery is a small flathead screwdriver used to pry apart the two halves of the fob. You could also use a coin, butter knife, nail file or a thin key. |

Pry Apart Two Halves |
Gently Push Out Old Battery |
Old Battery Removed |
The first step is
to locate the small notch at the bottom right corner of the key fob near the
red "Panic" button. You may choose to cover the tip of your flathead screwdriver with a thin micro fiber cloth to protect the plastic surfaces from being scratched. Insert the blade of the small flathead in to the notch and gently pry apart the two halves of the key fob. Push the old CR2032 battery out of the holder with your finger tip or very carefully use the flathead screwdriver. Try to avoid damaging the metal electrical contacts or the green plastic circuit board. |

Line up the two
halves of the key fob and gently pop them back together. Make sure that the
key fob is flush all the way around with no parts of the green rubber gasket
showing. Test the new key fob battery by standing near your Sienna and pressing the "Unlock" and "Lock" buttons. If the new battery is working properly, you should see the parking lights flash. For more,
