Identifying the Symptoms of a Dying Key Fob Battery

Before you start digging for a new battery, it’s important to be sure that your key fob‘s battery is actually the culprit. Here are some common signs that your key fob battery is running low:

Gathering Your Supplies

Before you begin, you’ll need a few essential supplies:

  • New Battery: Check your key fob’s manual or the back of the fob itself to find out what type of battery you need. Common types include CR2032, CR2025, and CR1620.

Sometimes, even after replacing the battery, your key fob might not work properly. Here are a few things to try:

  • Check Battery Placement: Ensure the new battery is correctly inserted with the positive (+) side facing up.
  • Reset Your Key Fob: Some key fobs have a reset button. Consult your owner’s manual for instructions on how to reset your key fob.
  • Consult Your Owner’s Manual: Your owner’s manual should contain detailed instructions on how to change your key fob battery and troubleshoot any issues.
  • Contact Your Dealership: If you’ve tried everything and your key fob still isn’t working, contact your car dealership for assistance.

Beyond the Battery: Maintaining Your Key Fob

Changing the battery is just one part of keeping your key fob in tip-top shape. Here are some additional tips:

  • Keep Your Key Fob Clean: Clean your key fob regularly with a soft, dry cloth to remove dirt and grime.
