I usually consider buying a small pack instead of a single battery. That way, I have a spare ready when the current one dies. I just make sure the batteries have a good expiration date so they stay fresh.
7. What I Check Before Installation
Before I install the new battery, I check the battery polarity and make sure the contacts inside the fob are clean. I also handle the battery carefully so I don’t damage the fob or reduce battery life with dirt or moisture.
8. Signs I Need a Replacement
I know it is time for a new battery when the key fob works only close to the vehicle, the buttons feel less responsive, or the dashboard shows a low key battery warning. These signs help me replace it before it fails completely.
