When it comes to home, office and business security, users consider locks one of the most fundamental aspects of any security system. Locks ensure people’s privacy, the safety of valuables and the security of homes and establishments from burglars and other intruders.

While the options available in the market can be overwhelming, each type of lock has its own purpose and function. Among the many types on offer, combination, cam, glass door, knob, rim latch, deadbolt and electronic locks and padlocks are the most common and frequently used. Typical materials include stainless steel, zinc alloy, solid brass and aluminum alloy.

In terms of market trends, both mechanical and electromechanical locks are predicted to rise at a CAGR of 5.79 percent from 2022 to 2027, according to Research and Markets’ latest global report. The growth, considering that both types already have a long-established global market, can be attributed to the increasing adoption of new doors in buildings, the global construction industry’s recovery from the impact of the COVID-19 pandemic, and the growing need for locks with digital access control capabilities.

The report added that the growing popularity of Internet of Things (IoT) and machine learning in various applications is providing significant growth opportunities for the electromechanical locks market. More users are increasingly opting for smart products that promote efficiency and save time while ensuring safety and security.
