Låsetyper

Låsetyper, or lock types, cover the range of devices used to secure doors, containers, and safes. They are commonly divided into mechanical and electronic categories, and further differentiated by mounting style, keying, and security level.

Mechanical locks include cylinder locks (pin-tumbler), lever locks, warded locks, disc-detainer locks, mortise locks, and deadbolts. Cylinder locks use stacks of pins that must be aligned by the correct key to allow rotation. Lever locks rely on a set of levers that must be lifted to permit movement of the bolt, offering robust security in many settings. Warded locks use matching wards in the key to permit or deny operation and are generally lower in security. Disc-detainer locks employ rotating discs with specific gate alignments to allow unlocking, and mortise locks are built into the door edge, often combining latch and deadbolt for higher security. Deadbolts provide a strong, separate bolt that resists forced entry, available in single- or double-cylinder configurations. Each mechanical type has typical applications, strengths, and vulnerabilities, and higher-security variants often feature more complex tolerances and keyways.

Electronic locks use electrical power to actuate a bolt and accept credentials such as PINs, RFID, smart cards, Bluetooth, or biometrics. They offer convenient access control, audit trails, and flexible administration, but depend on power and electronics and typically include a mechanical backup.

Specialized locks for safes, cabinets, and high-security applications include combination and time-delay safe locks, as well as master-keyed systems. Some locks blend mechanical and electronic components for resilience or advanced access control. Choosing a låsetyp depends on door type, risk level, maintenance, and cost.
