Heavy Duty Rust Proof And Long Durable Stainless Steel Silver Door Lock

Product Description

Mortise locks are not as common as cylinder locks because they are more expensive and difficult to install. Deadbolts are often installed on the inside of a door and are designed to prevent someone from kicking in the door. Deadbolts can be installed on both the inside and outside of a door, but the inside installation is less common. Deadbolts are usually locked by turning a key in a lock cylinder. A door lock is a security device that is installed on the inside of a door to prevent unauthorized entry. Door locks can be keyed to match a specific key, but most locks are unkeyed and rely on a matching strike plate on the door frame. There are a number of different types of door locks, each with their own advantages and disadvantages.
