Opening Your Key Fob
Before you can replace the battery in your Toyota key fob, you’ll need to know how to open it. Follow these simple steps to access the battery compartment:
- Locate the small groove: Find the small groove or indentation along the edge of the key fob, usually located on the side or bottom.
- Use a flathead screwdriver or pry tool: Carefully insert a small flathead screwdriver or a plastic pry tool into the groove.
- Gently twist or pry open: Gently twist the screwdriver or pry tool to separate the two halves of the key fob casing. Be cautious not to apply too much force, as you may damage the casing.
- Remove the battery compartment cover: Once the casing is open, you will see a small cover or a plastic tab securing the battery. Remove this cover to access the battery.
Changing the Battery on a Toyota Key Fob
Now that you have access to the battery, follow these steps to replace it:
- Remove the old battery: Carefully remove the old battery from the battery compartment using your fingers or a small tool. Note the orientation of the battery before removal, as you’ll need to insert the new battery in the same manner.
- Insert the new battery: Place the new battery into the battery compartment, ensuring the positive (+) side is facing up or in the same orientation as the old battery.
- Reassemble the key fob: Replace the battery compartment cover and press the two halves of the key fob casing together until they snap into place.
Selecting the Right Replacement Battery
When choosing a replacement battery for your Toyota key fob, consider the following:
- Compatibility: Ensure the battery is compatible with your specific Toyota key fob model. Common battery types include CR2032 and CR2016. Consult your owner’s manual or check the old battery to confirm the correct type.
- Quality: Opt for a reputable brand to ensure a longer-lasting battery life and better performance.
- Expiration date: Check the expiration date on the battery packaging to ensure it hasn’t expired. Batteries lose power over time, even when not in use.
Troubleshooting a Non-Working Toyota Key Fob
If you’ve replaced the battery in your Toyota key fob but it still isn’t working, try these troubleshooting tips:
- Inspect for damage: Carefully examine the key fob for any signs of damage or wear. If any components appear to be damaged, you may need to replace the entire key fob.
- Reset the key fob: Some Toyota key fobs may require a reset after replacing the battery. Consult your owner’s manual for specific reset instructions for your model.
- Check for programming issues: If your key fob still isn’t working after following the above steps, it may need to be reprogrammed. Refer to your owner’s manual for programming instructions or consult a Toyota dealer for assistance.
