Door Lock

A door lock is a mechanical or electronic device used to secure doors and prevent unauthorized access. It plays a crucial role in maintaining safety and privacy in homes, offices, and vehicles. Traditional locks include padlocks, deadbolts, and knob locks. Modern advancements have introduced electronic locks, smart locks, and biometric systems. These locks often offer keyless entry through codes, cards, or fingerprints. The lock mechanism typically involves a latch or bolt that fits into a strike plate. High-security locks are resistant to picking and drilling. Proper installation and maintenance enhance the lock’s effectiveness. Choosing the right lock depends on the level of security needed.
