Why Cylinder Locks Are a Great Choice

A homeowner can use cylinder locks for different purposes. You can use it on your front, back, side, and patio doors. Some homeowners also prefer cylinder locks because of their ideal size which makes them fit in internal and external doors. Of course, you cannot neglect affordability when comparing locks. The price point is a major reason why most homeowners opt for cylinder locks.

How Cylinder Locks Work

Immediately you insert the keys and turn it clockwise, it turns the cylinder and aligns all the pins for the lock to open. The mechanism also turns the cam pulls in on the bolt. On the other hand, you close it by turning the cylinder anticlockwise. This will release the bolt and the spring will snap into place to realign the pins. The cylinder locks are designed to open with a specific key and you will only gain access when you use the right key.

The internal components of the cylinder consist of pins and a spring. The upper pins are the most important component of the cylinder lock, they stop the cylinder from turning when the door is in a locked position. The keys have notches to enable each pin to move properly into the right position and height.

Cylinder Lock Installation

As we stated earlier, easy installation is one of the reasons people prefer the cylinder lock. The first step is to insert the cylinder in the shaped hole that passes through the door and lock. This way, the cylinder will be in the correct position when turning the key and it will be possible to move the latch and the deadbolt. After that, screw the cylinder in place, let it get in the hole on the lock plate and at the top of the cylinder. So to get it screwed into the threaded hole of the cylinder, you need to position it properly. Then complete the operation by fitting the security coverings to safeguard the hole for passage of the cylinder through the door.
