How do I replace a Toyota Corolla key battery?

I have a 2016 Toyota Corolla and I think the battery in my key fob is dying because my car takes a few button presses to lock/unlock. I’m getting pretty annoyed with it, so I’m ready to try and replace the battery. I don’t know what battery to use or how to even open the dang thing. I need to know how to replace a Toyota Corolla key battery.

It can be frustrating dealing with a dying car key battery, but lucky for you I’m here to help. Changing the battery in your
Toyota Corolla’s
key fob is easy!
Before you get started, you’re going to need a small flathead screwdriver (or a coin if you don’t have a screwdriver on-hand) and a 2016 3V button cell battery.
To change the battery on your Toyota Corolla’s key fob, do the following:
  • Step One: Locate a small opening or groove on the edge of your key fob. Gently pry the key open using either a small screwdriver or coin on the opening and twist.
  • Step Two: Once your key fob is open, you will notice a small plastic shell inside the case. Pry this piece apart exactly like Step One to gain access to the battery.
  • Step Three: Remove the battery by locating the tiny opening under the battery to pry it up.
  • Step Four: Place the new battery in the key with the positive (+) side facing upwards.
  • Step Five: Click the plastic pieces back together and your key fob should be ready to go.
