If there is a fire or other emergency at your home, a locked door can slow down firefighters or paramedics. They may need to break the door to get in. County Fire can give qualified residents a lock box with a key that firefighters can use to enter your home.  

The box is called a KnoxBox. It is free. County Fire will install the box.
