years) Toyota Camry sedan in changing a weak or dead battery in the
intelligent or "smart" key fob remote control for the keyless entry and push

Owners of other Toyota, Scion and Lexus vehicles such as the Avalon, Corolla, Prius, Yaris, Mirai, 86, Sienna, RAV4, Highlander, 4Runner, C-HR, Land Cruiser, Sequoia, Tacoma, Tundra, Venza, Hilux, RX 350, IS 250, IS 350, CT 200H, GS 450h, GX 470, LX 470, UX 200, NX 300 and UX 250h may also find these DIY instructions to be helpful. The compatible replacement coin cell (also known as a "button" or "watch") battery part number is CR2032 which is available from manufacturers such as Panasonic, GE, Energizer, Sony and Maxell. The only tool needed to access and replace the battery is a small flathead screwdriver or a small plastic pry bar tool. |

Insert Screwdriver |
Pry Off Rear Cover |
Red Plastic Battery Cap |
The first step is
to separate your key ring and other keys from the fob. Then turn over the fob and locate the small notch at the bottom corner near the silver key ring loop. To prevent from scratching the plastic surfaces, you may choose to either cover the tip of your screwdriver with a thin micro fiber cloth or instead use a plastic pry bar tool. Insert the blade of your screwdriver into the small notch and gently pry off the rear access cover on the back side of the fob. Set the back cover aside in a safe place. |

Gently pop the rear
cover back into place on the back side of the fob. Make sure the cover is flush with the fob at every edge. To test the new battery, stand near your car and press the "Unlock" and "Lock" buttons. If the new battery was properly installed and working, you should see the parking lights flash and also hear the door locks opening or closing. (You shouldn't have to re-program the key fob. Just replacing the battery should not clear the existing programming.) Be sure to record the fob battery change in your vehicle's service records. For more,
