How To Test Key Fob Battery Life
Check if the LED light turns on when pressing buttons. No light often means the battery is dead. Use a spare key fob if available to compare. Replace the battery if the light is weak or absent.

Quick Battery Replacement Tips
Replacing your key fob battery is easy and saves time. A fresh battery keeps your remote working perfectly. Follow simple tips to choose and swap the battery correctly.
Choosing The Right Battery
Check the old battery for its type and size. Most key fobs use coin cell batteries like CR2032 or CR2025. The numbers on the battery show its size and power. Use the exact same type to avoid issues. Buy fresh batteries from a reliable store. Avoid cheap or old batteries to ensure long life.
Step-by-step Battery Swap
Start by opening your key fob case carefully. Use a small flat tool or your fingernail to pry it open. Remove the old battery gently. Note the battery’s positive (+) and negative (-) sides. Place the new battery in the same position. Press the case parts back together until they click. Test the key fob immediately to check it works.

Gently clean the metal contacts inside. Let them dry completely before closing the case. Clean contacts improve connection and response.
Resetting Your Key Fob
Resetting your key fob can fix many glitches. Remove the battery and wait for 10 seconds. Press all buttons once to drain leftover power. Insert the battery back into its place. Press the lock and unlock buttons together for a few seconds. This resets the key fob’s system. Try it again with your car. This often clears minor errors and restores function.
