2018 RAV4 Key Fob Battery: What You Need to Know

The key fob for your 2018 Toyota RAV4 is a complex piece of technology that makes your life easier. But like all technology reliant on batteries, eventually, that battery will need to be replaced. Knowing how to identify when your key fob battery is failing, how to change it, and even what type of battery it uses can save you time, money, and a lot of frustration.

Signs Your 2018 RAV4 Key Fob Battery Needs Replacing

Sometimes your key fob will give you warning signs that the battery is failing. Be on the lookout for:

Decreased signal strength: Are you noticing that you need to be closer to your RAV4 to lock or unlock the doors? This is a classic sign your key fob battery is dying.
Inconsistent response: Does your RAV4 sometimes respond to the key fob and sometimes not, even when you’re in range? This too can indicate a failing battery.
Dashboard warning light: Some RAV4 models will display a warning light on the dashboard if your key fob battery is low.

If you are experiencing any of these issues, it’s time to consider replacing your key fob battery.

What Type of Battery Does a 2018 RAV4 Key Fob Use?

The 2018 RAV4 key fob uses a CR2032 battery, a common type of lithium coin battery. You can find these batteries at most supermarkets, electronics stores, and auto parts stores.

How to Change the Battery in Your 2018 RAV4 Key Fob

Replacing the battery in your 2018 RAV4 key fob is a relatively simple task that most people can do at home. Here’s a step-by-step guide:

Locate the release button on the back of your key fob. It’s often a small, indented button.
Use a small flathead screwdriver or a fingernail to press the release button while gently sliding the key fob cover apart.
Identify the old battery. It will be housed in a small compartment within the key fob.
Carefully remove the old battery and note which side is facing up (usually positive (+)).
Insert the new CR2032 battery into the compartment, making sure the positive (+) side faces the same direction as the old battery.
Align the key fob cover and press it firmly back together until you hear a click.
Test your key fob to ensure the new battery is working correctly.

Avoid frequent drops or impacts: Dropping your key fob can damage the battery or its connections.

Don’t leave your key fob in direct sunlight for extended periods: Heat from the sun can damage the battery.
