As such, it’s important to keep your key fob in good working order.

Here are a few tips for doing just that:

  • Replace the batteries regularly. Just like any other type of battery, car key batteries will eventually die. When they do, be sure to replace them promptly. Most car manufacturers recommend replacing the batteries every two years or so.
