A lock box is the perfect companion accessory to a medical alert system, because it allows you to provide access to your home in the event of an emergency. Without it, emergency medical services (EMS) will enter your home by any means necessary to reach you, which can mean broken windows or doors – a traumatic and costly experience. With an emergency lock box available, EMS will have the passcode they need to retrieve your key and enter your residence to get you the help you need.
