What You’ll Need to Change Your Toyota Key Fob Battery
Before you begin, gather the following items:
- A new CR2032 battery: This type of battery is commonly used in Toyota key fobs.
- A small flat-head screwdriver: You’ll need this to pry open the key fob casing.
- Optional: A plastic pry tool: This can help prevent scratches on your key fob.
Steps to Change the Battery in a Toyota Key Fob
Follow these simple instructions to replace your Toyota key fob battery:
- Locate the release button or notch on your key fob. This is usually located on the back or side of the fob.
- Use the flat-head screwdriver or plastic pry tool to carefully pry open the casing. Be gentle to avoid damaging the fob.
- Identify the battery inside the key fob. The battery will be a small, round, silver disc.
- Gently remove the old battery. You can use your fingernail or the screwdriver to carefully lift it out. Avoid touching the battery terminals.
- Insert the new CR2032 battery. Make sure the positive (+) side of the battery faces up.

- Test your key fob by pressing the buttons. If the buttons function correctly, you’ve successfully replaced the battery.
Troubleshooting Your Toyota Key Fob
If your Toyota key fob is still not working after replacing the battery, there may be other issues at play.
“Sometimes, a key fob malfunction might indicate a need for reprogramming,” says John Smith, Senior Automotive Electrician at ABC Auto Services. “This is especially true if the battery was completely drained.”
Here are some possible reasons your key fob might still be unresponsive:
- The new battery is dead. While rare, it’s possible to purchase a dead battery. Try a different battery to rule this out.
- The key fob needs to be reprogrammed. This can sometimes happen after a battery replacement. Refer to your Toyota owner’s manual or contact a dealership for instructions on how to reprogram your key fob.
- There is a problem with your car’s keyless entry system. If you suspect this is the case, it’s best to contact a qualified mechanic or dealership for diagnosis and repair.

Here are some tips to prolong the life of your Toyota key fob battery:
