Turvalukud

Turvalukud are locking devices designed to secure doors and gates by resisting unauthorized access and forced entry. They are distinguished from standard locks by stronger construction, more resistant cylinders, and often multi-point locking mechanisms. Turvalukud are used in homes, offices and other buildings where higher security is desired.

A typical turvalukk may combine a high-security cylinder with anti-pick, anti-drill and anti-bump features, reinforced housings, and hardened bolts. Many turvalukud employ multipoint locking systems that engage at several points along the door frame for greater resistance to levering and forced entry. They come in various forms, including mortise, rim, and pedestal (central) types, and may be paired with electronic components or restricted-key systems to control key duplication.

Standards and certification: Security locks sold in Europe and other regions are often evaluated according to standards such as EN 1303 for cylinders, EN 12209/12210 for locks, and EN 1627-1630 for door sets and locking devices. Independent certifications (for example SKG, BSI) indicate tested resistance grades. Manufacturers typically publish the level of physical resistance and key-control arrangements.

Installation and maintenance: Proper installation by a qualified locksmith is essential to ensure alignment with the door and frame, adequate reinforcement of strike plates, and correct functioning of the locking mechanism. Regular maintenance includes lubrication, inspection for wear, and management of keys to prevent unauthorized duplication.
