The greatest security threat to your building might be located right outside the front door. In the past couple weeks, Calgary has seen a string of building break-ins using the keys from their own lockbox.
How is this possible? Apparently there is a structural weakness present in lockboxes that have a lip. The lip is used to pry open the lock box with a crowbar. Take a look at our photos below for more details.
The lockbox in the image above contained a lip with which a crowbar can be lodged. The sheer force against the lip was able to break the door of lockbox and make the keys within accessible.
