Recognizing a Dying Key Fob Battery
How do you know if your key fob battery needs replacing? Look out for these telltale signs:

If you’re experiencing any of these issues, it’s a good indicator that a battery replacement is in order.
What You’ll Need
Replacing the key fob battery requires just a few common household items:
- A new CR2032 battery: This type of battery is widely available at most grocery stores, pharmacies, and online retailers.
