Editor's Pick: If your car key fob suddenly stops responding when you press it, it's most likely time to replace the A23 battery inside. Garage door remotes, Bluetooth trackers, and other small devices use them too. Keep a few in a drawer so you're not stuck running out to find one at the last minute.
