Solenoids in Security Locking Mechanisms

A look at modern, technology-driven, security-focused locking mechanisms using solenoids

Security is critical in every aspect of our lives… from protecting personal valuables, important documents, and sensitive paperwork to the way we enter buildings, withdraw money and even open our garage doors. As our technology progresses, so do the ways in which we enhance security all around us.


Many businesses are still using old-fashioned lock and key systems as their primary security measure. However, the industry and security system installers are moving toward electronic locking mechanisms.

With an access control system, the swipe of a badge or a keyfob tap gives people access to their businesses; this happens without ever sticking a key into a lock. These systems are more secure than the traditional lock and key and more reliable than digital keypads and codes.

Whether you scan an ID badge or swipe a keyfob, there’s one thing all access control systems have in common. The security turnstiles, maglocks, doors, and other electronic locking mechanisms that protect us and our businesses require the use of actuation devices.

Security powered by solenoids

A solenoid locking mechanism is one of the most effective ways to protect employees and businesses; from security breaches, break-ins, and other security issues.

Most security programs utilize programmed credential devices. Each device has a personal identification number assigned to each individual; these can be programmed to allow or disallow entry at any time. Since the building is only accessible with RFID badges, it’s much more difficult for terminated employees to enter their building; their keyfob would no longer be activated.

In addition to the obvious advantages over the old-fashioned lock and key systems, a solenoid lock has greater design flexibility and enhances security for businesses and personnel.

Enhanced security

With the frequency of people entering and exiting hospitals, government offices, schools, and venues, security is increasingly a top concern.

With an access control system, businesses can grant clearance to certain parts of the building only to specific individuals. They can also use added sensors in lock assemblies to detect the positioning of the door latch; this ensures security breaches remain at a minimum, with no doors left ajar or alert security to any malfunctions.

With solenoids as the main driver for your system, the lock can be decoupled from the actuation device. This provides added G-Force resistance, so that the locks aren’t easily opened by external force.

Electromechanical locks also have paved the way for the growth of biometric options; these are even more secure than using keyfobs or ID badges. Employers are now using facial recognition or finger-vein biometric authenticators. This can be easier to manage by both employees and security personnel.

Design Flexibility

The design of solenoid locks can vary greatly by application; from simple drop-in replacements to full locking assemblies that are ready to mount into your system. This gives a large amount of flexibility and convenience in the design process; there is a solution available for all sizes of locks.


The convenience of solenoid-based locking doesn’t just extend to the design of the lock, but also the systems that use cloud-based functionality; these can predict when the locking system will need maintenance or a replacement, instead of waiting for issues to arise. This provides not only an added benefit to the end user, but to the manufacturer as well.
