Why Does My Key Fob Battery Die?

Like any battery, your Toyota RAV4 key fob battery has a limited lifespan. Over time, it loses its ability to hold a charge. How long the battery lasts depends on factors like how often you use your key fob and even the climate you live in. Here are some telltale signs that your key fob battery might be on its way out:

Decreased Range: You find yourself having to stand closer to your RAV4 to lock or unlock the doors.
Intermittent Functioning: The key fob works sometimes, but not others.
No Response: Your RAV4 doesn’t respond at all to the key fob.

What You’ll Need for a Toyota RAV4 Key Fob Battery Replacement

Don’t worry, you won’t need a mechanic’s toolbox for this job! Here are the basic tools you’ll need:

A small flat-head screwdriver: This is to pry open the key fob casing.
A fresh CR2032 battery: This is the standard battery for most Toyota RAV4 key fobs.
