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.

  2. 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.
  3. 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.
