Woman unlocking 2020 Toyota RAV4

Life doesn’t always go perfectly, and in the course of events, you may be left with a non-functioning or missing Toyota key fob. Fortunately, Toyota key fob battery replacement is easy, and we’re here to help. And if you’re interested in a new Toyota, we offer convenient online shopping to get you started at home.

Replacing a Toyota Key Fob Battery

When your Toyota key fob battery has stopped working, you’ll have to open up your key fob case to figure out what kind of battery is inside it. With newer Toyota cars, you can open up your key fob case by unfolding the hidden key and placing it in a slot specially designed to open the case. In older Toyotas, you’ll unlock the case by sticking a thin object to pry the case open where you see a notch that stands out.

Here are the steps to replace a Toyota key fob battery:

  1. Open up your key fob with any of the appropriate above methods.
  2. Once you open the case, lift up the circuit board and find the battery.
  3. Make a note of what kind of battery it is and the way it sits in the case. Usually, you’ll find a CR2032 battery which you can find all over Monterey hardware stores and big box retailers. There are normally below $5 at most places.
  4. After getting your Toyota key fob battery replacement, place it in your key fob case and close the key fob.
  5. Test out your key fob with the battery replaced. If it isn’t working, open the case again and make sure the connections are clean and they’re making contact with the battery. If you’re still having trouble, you should get a Toyota key fob replacement or reach out to our service department.
