Types of Electronic Door Locks
As the desire for smarter security increased in both commercial buildings and residential homes, the electronic lock system has seen many variations. There are now many types of electronic locking systems, each with varying technologies and benefits for specific areas. Let’s discuss the most recognizable types of electric locks and how they work:
Magnetic Locks
Magnetic locks (also known as maglocks or EM locks) utilize an electromagnet to hold the door closed to an armature plate on the door. This electronic lock system for door mechanism generates a magnetic field that connects with the armature plate, securing the door when closed – often with more than 1,000 pounds of holding force. To unlock the door, power is interrupted by an access command such as a swipe on a card reader or entering a keypad code.
They require powered assistance for locking and unlocking; hence, their fail-safe design means that they unlock when power fails, which is why they are an excellent choice for emergency exits.
Magnetic electronic lock systems are extensively used on commercial doors, glass doors, and any application where high security and fast locking are essential.

Electric Strike Locks
Electric strike locks operate in conjunction with standard mechanical locks such as latch bolts or deadbolts. Electric strikes do not secure directly to the door; instead, they replace the static strike plate that is fixed to the doorframe. So when access is allowed, it only pivots or releases momentarily and does not allow the door to open and be turned by the handle.
The attractiveness of electronic lock systems for doors with electric strikes is their flexibility; electric strikes can be used with keypads, RFID readers, intercoms, or remote access. Electric strike locks can also be fail-safe and fail-secure; therefore, electric strikes can unlock or stay locked during a power failure, depending on the power supply installation.
Electric strike locks are found in office entryways, apartment complexes, and secure reception areas.
Electric Cylindrical and Electric Mortise Locks
Electric cylindrical and electric mortise locks have gained popularity as an upgrade to traditional mechanical locks by leveraging both strength and electronic access. These types of electric locks are installed directly into the door, incorporating a motorized locking mechanism controlled with electronic signals from the credential system (keycard, fob, and/or biometric scanner).
Electric cylindrical locks are easier to retrofit to existing doors and are well-suited for light to medium-duty applications, such as interior office doors. Electric mortise locks require larger and deeper installation and will offer greater durability, making them suitable for less sheltered points of entry or continuous duty in high-traffic commercial areas.

Both electric locks offer enhanced access control, audit trails, and the ability to integrate within a larger integrated security system.
Electric Push Bar Locks
Electric push bar locks, or electrified panic bars, merge secure entry control with emergency egress. They can typically be found on exit doors in commercial and public buildings. The push bar allows people to exit quickly, while keeping unauthorized entry from the outside.
The technology consists of enclosing a solenoid or motor-driven mechanism inside the push bar, which can form part of electronic access systems like card readers or building automation systems. Access is allowed by electronic latch retraction to allow the door to open when the outside push bar is not depressed.
Among the types of electronic locking systems for doors, this is especially useful for fire exits and for safety code compliance, as it achieves emergency egress while securing the entry.
Biometric & Keypad Locks
Identified as one of the safest, easy-to-use systems of electronic locking systems, biometric and password-protected electronic locks avoid the use of keys or cards. Instead, they come with the use of a PIN code or fingerprint, or even facial recognition. Biometric locks (primarily point of entry) will use a sensor to scan fingerprints – unique biological characteristics, such as a retina pattern – for allowing access to previously authorized users. In comparison, keypad locks require entering a numeric code for entry, which can be assigned or modified.

Both biometric and keypad locks provide excellent convenience and secure tracking, being used in residential apartments, offices, and more data-sensitive environments.
Electric Bolt Locks
Electric bolt locks, also known as drop bolt locks or solenoid bolt locks, offer a discreet yet strong locking mechanism. Electric bolt locks enable a metal bolt to engage into the door frame when energized, which means the door is physically locked. Once access is granted, the bolt retracts and the door can swing open.

Bolt lock technology is used for sliding doors, glass doors, and server cabinets, where other electronic lock systems typically don’t have room. Bolt locks provide high-precision locking technology and are commonly used for various forms of biometric readers, RFID, and access control panels.
Electric bolt locks typically function as fail-safe mechanisms, meaning the bolts will retract in the event of a power outage. These locks are preferred for their quiet functionality, sleek design, and remarkable durability in locking.
Radio Frequency Identification (RFID) Security Locks
RFID security locks are one of the most common electronic lock systems for door locks in hotels, offices, and shared access buildings. RFID locks work by reading a unique radio signal received from an RFID card, tag, or mobile device. The lock receives the signal data and allows or denies access according to predetermined access levels when an authorized credential is presented to the RFID reader.
The RFID technology itself is not limited to contact or line-of-sight operation, meaning access can be fast and seamless. It is also easy to reprogram missing or stolen cards to increase security without having to change the locks.
These types of electric locks are popular because of their ability to scale and integrate with a centralized access control system.

Electronic Door Lock Safety
When we think about securing any environment, safety and security are more than just keeping people out; they also incorporate feasibility during times of power outages, emergencies, and day-to-day operations. Electronic lock systems for doors are built to not only allow for convenience and control, but also incorporate safety standards and regulations.
Undoubtedly, electronic lock systems are generally very safe, and often safer than mechanical lock alternatives. Many models allow encryption, multi-level authentication, and integration with alarm systems. The reliability of electronic systems is that they can track access, prevent unauthorized access, and configure users’ permissions.
As with the U.S. and Canada, electronic locking systems are regulated regarding safety and fire codes. In Europe, standards such as EN 14846 and EN 179 encompass the installation and performance of electric locks on fire doors and emergency exits. Established safety standards ensure lock releases are accomplished safely in an emergency and do not prevent egress. Installers and facility managers must also follow building codes in terms of safety and any accessibility requirements to ensure that all users can evacuate without hindrance, including users with disabilities.
Among the important safety issues inherent in electronic lock systems is the difference between “fail-safe” and “fail-secure.”
- Locks designed with fail-safe mechanisms will unlock in case of power outages. These are generally applied in scenarios where safety is the priority (such as in emergency exits, stairs, or fire doors), allowing evacuation of occupants even during power outages.
- Failure-secure locks, however, remain locked when there is no power, or the power supply is cut off. These are used in locations where security is the priority, like server rooms or data centers that must prevent unauthorized access during power outages.
The option is always based on the function of the door and life safety versus asset protection. The highest quality types of electric lock options, like those at EOS Secure, carry both options, which is a big advantage in meeting your security and compliance needs.
