Notch At Bottom Left
Insert Small Screwdriver
This automotive "how-to" guide was specifically written to assist owners of the XV50 seventh generation (2012, 2013, 2014, 2015 & 2016) Toyota Camry in changing the battery in the keyless entry system's key fob remote control.

Owners of other Toyota, Scion or Lexus vehicles such as the Yaris, Corolla, Matrix, RAV4, Prius, Tacoma, Tundra, Sienna, FJ Cruiser, Venza, Highlander, Avalon, 4Runner, Land Runner, Sequoia, 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, "button" or "watch" cell key fob battery is part number CR2016 available from various manufacturers such as Panasonic, GE, Energizer, Duracell and Sony.

The only tool needed to replace the battery is a small flat head screwdriver.

Pry Apart Two Halves
Key Fob Separated
Re-Insert Plastic Buttons
The first two steps are to remove the key ring and locate the small notch at the bottom left of the fob near the trunk opener button.

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

If the plastic buttons popped out of place, re-insert them in to the appropriate holes in the top half of the fob attached to the metal ignition key.

Remove Remote Unit
Gently Pry Open Remote
Push In Plastic Tabs
Pop the remote control unit out of the key fob case.

Gently insert the blade of the small flathead screwdriver in to the sides of the remote control unit.

Push in the clear plastic tabs and pry apart the black plastic cover from the clear plastic piece.

You may need to push in several of the clear plastic tabs on the edge of the remote unit to pry off the black plastic back cover.

Try to avoid using excessive force.

Old Battery Removed
Turn over the remote unit to pop out the old battery or very gently use the flathead screwdriver to remove it.

If you use the flathead screwdriver to remove the battery, make sure you do not damage the remote control circuit board or metal electrical contacts.

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

Insert a new CR2016 3 volt coin in to the battery holder on the remote control unit with the positive "+" side facing up towards you.

Line up the black plastic rear cover of the remote control unit and gently snap it back in to place.

Make sure that all of the clear plastic tabs on the edges of the remote unit are fully seated in the slots on the sides of the black plastic cover.

Line Up Rear Cover
Make sure that the plastic "Lock", "Unlock", panic, and trunk opener buttons are properly seated in the top half of the key fob.

Test New Fob Battery
Line up the rear cover of the key fob with the top half and gently snap them together.

Make sure that the two halves of the fob are flush together all the way around.

Test the new key fob battery by standing near your Camry and pressing the "Lock" or "Unlock" buttons. If the new battery is working properly, you should see the parking lights flash and/or hear some beeping sounds.
