When people buy a front door for their home, they think that what they are buying is actually secure. This expectation of safety is actually not real, as anybody with a bit of training will be able to pick the lock of a typical door, and that’s not even mentioning just using brute force to force their way in. The solution to this problem is to get a door which is advertised as a security door.
Security doors differ from more typical doors in a number of ways. They are highly engineered, usually designed with multiple layers, all so that the door can diffuse the power from any impact and remain undamaged and unbroken. They also, of course, have considerably more advanced locking systems. As a basic model, you’ll get a normal locking mechanism (ie. one with a physical key), although it will still be more secure than a usual lock, but you can also get other types of locking mechanisms which can be installed in the door, such as keycard access or even fingerprinting.
