• The Pin & Tumbler Lock
This is the most common door lock that has several pins that are loaded with springs. They are then loaded into a set of tiny cylinders. Every cylinder will have a bottom part that is called a pin, along with a top part that is called the driver. Once you insert the key, each spring will be compressed while the key raises the pin and pushing the driver into the top section of the cylinder.
If you insert the correct key in the lock, the top and bottom pins will align the shear line. This is a space between the top and bottom pins that is around the track. Once each pin and driver are aligned to create a way for the shear line, then the key will turn.
When the key is not inserted into the lock, then the pins should be at rest inside the chambers. The bottom pin should be in the key chamber. On the other hand, the top pin section should rest on top of the bottom half of the key chamber. This will help to reduce the pressure on the springs.
If the wrong key is inserted, it will misalign one or more cylinders that have the locking springs. This will block the key from turning. This is why an incorrect key cannot open a lock that has a specified key.
• Side-locking Bar Lock

The side-locking bar has been designed to prevent lock bumping, a new way of breaking in.

• Mortise Locks

• Rim locks
The rim lock is a locking device, which is linked to the door surface. It will mostly be attached on the inside surface of the door. It entails a tiny latch that will be used to unlock the door from the inside. There will be a smaller rim that has a keyhole on the outside, probably or the sake of security.
• Electronic Locks
The electric locks will be controlled by an electric current. They are mostly stand-alone locks that have an electronic control system that is installed to the lock. Here, you will be needed to insert a combination code or a specified key to open up the lock system. If the combination is correct, the lock will be automatically be opened and you can access the building or safe.
• Mechanical locks
The mechanical lock will function with one or more metal pieces. The metal pieces include levers, latches, and tumblers. They will fall into a slot that is inside the bolt.
