The benefits of changing your key fob battery regularly

It’s important to stay on top of your key fob’s battery life. A dead battery can cause problems such as difficulty unlocking your car or starting the engine. Regularly changing your key fob battery will keep your fob functioning properly and prevent you from getting locked out of your vehicle.

If you’re facing these issues, it’s best to troubleshoot the problems first before replacing the battery. If you do replace the battery and the problems still persist, it may be time to get your key fob checked by a professional.
