Locks are fastening devices that can either be electronic or mechanical. They can be opened using any of the following: key, keycard, password and fingerprint. They are used to provide safety, security and protection to those residing in a room, house and building. Modern security locks can be integrated to a computerized system for improved security strength.

Industrial revolution has paved the way for the invention and production of different door lock types for residential, commercial and industrial applications.
• Padlock is one of the most common types of locks used due to its portability. It is made of three components: body, shackle and locking mechanism.
• Electric Lock employs motors, magnets and solenoids for power delivery and removal. These are integrated to an access control system for authentication, prevention and operation.
• Deadbolt is used together with a spring-bolt lock on doors for better security door locks. They can only be opened if its lock cylinder is rotated using correct key.
• Combination Lock does not require keys to be opened. It needs the correct combination of either letters or numbers to be opened.
• Magnetic Lock is a fail-safe type of locking device made from armature plate and electromagnet. The electromagnet component is attached on a door frame while the armature plate is on the door.
• Cylinder Lock is made with an easy to change cylinder without modifying its boltwork.
• Keycard Lock is mainly used in hotels and automated parking lots. This is typically made from plastic card with a rectangular shape. The plastic card has stored information that is used for disengaging locking mechanisms.
