Is your Toyota key fob acting up? Before you rush to the dealership, a dead battery might be the culprit. Replacing it is a surprisingly simple task that can save you time and money. This comprehensive guide will walk you through everything you need to know about replacing your Toyota key fob battery, from identifying the signs of a low battery to choosing the right replacement.
How Do You Know Your Toyota Key Fob Battery Needs Replacing?
Key fobs aren’t equipped with a “low battery” warning light, but your car will give you some hints:
- Decreased Range: Do you find yourself standing closer to your car to lock or unlock it? A fading battery could be the reason.
- Unresponsive Buttons: If you have to press the buttons multiple times to elicit a response, it’s a clear sign your battery is losing power.
- Intermittent Functioning: Does your key fob work sometimes but not others? This erratic behavior is another indicator of a dying battery.
- Security System Malfunctions: In some cases, a weak key fob battery can lead to issues with your car alarm or remote start system.
What Kind of Battery Does a Toyota Key Fob Use?
Most Toyota key fobs use a standard CR2032 battery, a common type readily available at most supermarkets, drug stores, and online retailers. It’s always a good idea to check your owner’s manual or the back of your existing key fob to confirm the specific battery type before purchasing a replacement.
Tools You’ll Need to Replace Your Toyota Key Fob Battery
You won’t need a toolbox full of equipment for this task. Here’s all you’ll need:
- A new CR2032 battery
- A small flat-head screwdriver or a plastic pry tool
Steps to Replace the Battery in Your Toyota Key Fob
Replacing the battery in your Toyota key fob is a straightforward process:
- Locate the Release Tab or Notch: Examine your key fob for a small release tab or notch. This is usually located on the back or side of the fob.
- Open the Key Fob: Gently insert the flat-head screwdriver or pry tool into the release tab and carefully pry open the key fob casing. Be cautious not to use excessive force, as this could damage the fob.
- Remove the Old Battery: With the casing open, you should see the old CR2032 battery. Gently pry out the old battery and dispose of it properly.
- Install the New Battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, just like the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating the fob is securely closed.
- Test Your Key Fob: Check to make sure all buttons on your key fob are functioning properly.

What to Do if Your Toyota Key Fob Still Doesn’t Work After Battery Replacement
If you’ve replaced the battery and your key fob still isn’t functioning correctly, there could be a few reasons why:

- Key Fob Programming: Some Toyota key fobs may require reprogramming after a battery replacement. Consult your owner’s manual or contact a qualified locksmith or dealership for assistance.
