#2 Why Use Different Door Cylinders?

They offer little real protection for homes and are easy to tamper with for anyone who understands how they work.
#3 How Do Door Cylinders Work?
Despite their simple appearance, there’s actually some smart innovation going on inside the latest family of door cylinders. The cylinder runs along the exact central line of a mechanism. Although you don’t see it, there’s plenty going on when you unlock a door. The mechanical parts inside the cylinder have to work in conjunction with the key for the lock to function effortlessly. The “tang” is one of these parts that sit inside the central area of a cylinder when the door is unlocked. When the door is in lock mode, the tang is both inside and outside the cylinder, keeping the door secure and locked tight. A door key triggers the mechanism that locks and releases the tang.
As you turn the key to lock a door, you also turn the cylinder. When this happens, a strong spring forces the tang into its fastened position, thus securing the door. With some doors, on the inside, there’s a central button that you can press to lock it. It actually does the same job inside the cylinder as a key, but in much less time. Obviously you still need a key to open the locked door from the outside. There’s a bit more to a door cylinder than this, but these are its basic workings.
An experienced burglar won’t have any problem breaking or picking the locks on doors with weak cylinders. A strong door cylinder, one that uses the newer technologies, will help to prevent people from breaking in. There are other layers of door security, but making sure you have tough door cylinders is a crucial first step.
