How Often Should You Change Your Key Fob Battery?
Few things are more frustrating than being stranded with a non-working key fob, especially during a long trip or in an emergency. Many drivers overlook key fob battery maintenance, only to realize too late that their fob no longer functions properly. To avoid unexpected issues, it’s essential to replace your key fob battery regularly.
How Long Do Key Fob Batteries Last?
On average, a key fob battery lasts between 3 to 4 years, depending on usage and battery quality. However, factors such as extreme temperatures, frequent use, and weak battery brands can shorten this lifespan.
Signs That Your Key Fob Battery Is Dying
1. Reduced Range: If your key fob only works when held very close to the car, it may be time for a battery change.
2. Intermittent Functionality: If the fob sometimes works and sometimes doesn’t, the battery is likely weakening.
3. Warning Light on Dashboard: Some vehicles display a low-key fob battery warning on the dashboard.
4. Unresponsive Buttons: If pressing buttons multiple times is necessary, a failing battery could be the cause.
When Should You Replace Your Key Fob Battery?
To avoid surprises, it’s best to replace your key fob battery every 2 to 3 years as preventive maintenance. If you rely on your vehicle for long trips or daily commuting, checking and replacing the battery before a long journey is a wise precaution.
How to Replace Your Key Fob Battery
1. Check the Battery Type: Most key fobs use CR2032 or CR2025 batteries, but check your manual or current battery.
2. Open the Key Fob: Use a small screwdriver or pry tool to open the casing.
3. Replace the Battery: Remove the old battery, insert the new one with the correct polarity, and close the shell securely.
4. Test the Key Fob: Ensure all buttons function properly before resuming use.
