“Door lock” is a generic term referring to a device used to secure doors, preventing unauthorized access. There are various types of door locks, each with its own mechanism and level of security. Here are some common types of door locks:
Cylinder Lock: This is the most common type of lock, operated with a key. It can be a single-cylinder (key on one side, thumb turn on the other) or a double-cylinder (key required on both sides).
Deadbolt Locks:
Single Deadbolt: A single-cylinder deadbolt lock requires a key on one side and a twist knob on the other.
Double Deadbolt: A double-cylinder deadbolt requires a key on both sides, offering extra security but may pose safety concerns in emergencies.
Mortise Locks:
Mortise locks are often found in commercial and high-security applications. They are installed within the door and have a complex mechanism for increased security.
Card Access Systems:
Electronic Locks:
Keypad Locks: These locks use a keypad to enter a PIN code for entry.
Smart Locks: Smart locks can be controlled remotely through a smartphone app and often have features like keyless entry, remote access, and integration with home automation systems.
Biometric Locks: These locks use fingerprint recognition technology for access control.
Often used in commercial settings, card access systems use RFID or magnetic stripe cards for entry.
Chain Locks and Slide Bolts:
These provide additional security when the door is partially open, allowing limited visibility and interaction with visitors.
Cam Locks:
Commonly used in cabinets and mailboxes, cam locks are simple and secure for small applications.
Knob Locks:
Typically used on interior doors, knob locks are less secure than deadbolts and can be vulnerable to forced entry.
Interconnected Locksets:
Commonly used in residential buildings, interconnected locksets have two locks in one unit, often used for the deadlatch function (night latch).
