Magnetic Locks vs Electric Strikes for Commercial Doors

Your commercial door needs controlled access, but which locking system actually makes sense for your building?  

Magnetic locks and electric strikes can both connect a door to an access control system, yet they work in very different ways. Choosing the wrong option can create installation problems, affect how employees enter and exit, or leave you paying for hardware that does not suit the door. Knowing how each system works makes the decision much easier. The right choice depends on the door itself, the existing lock, daily traffic, security needs, and how the door must behave during a power failure or emergency. 

How Magnetic Locks and Electric Strikes Work 

Magnetic locks, also called mag locks, use an electromagnet and an armature plate to hold the door closed. Power creates the magnetic force that secures the door. Removing power releases the door. Electric strikes take a different approach. Instead of replacing the entire mechanical locking system, the strike is installed in the door frame and works with the existing lock or panic hardware. An access credential releases the strike so the door can open. That difference matters when you are deciding what will work best with your existing commercial door. 

Magnetic Locks: Where They Make Sense 

Magnetic locks can be useful when the door needs electronic access control without relying on a traditional latch to hold it closed. 

Installation Can Work Well on Certain Doors 

Mag locks use two main components: the magnet and the armature plate. Installation can be less invasive than some other electronic locking options because the system does not need a mechanical latch bolt to lock the door. 

Glass doors can also make mag locks worth considering when traditional lock hardware is difficult to install. 

Keep the door design in mind before choosing this option. The available mounting surface, frame, door type, and existing hardware all affect whether a magnetic lock is practical. 

Power Loss Changes How the Lock Behaves 

Magnetic locks are fail-safe by design. Power must be present for the magnet to keep the door locked, so removing power releases the lock. That feature can be useful for certain emergency-access situations, but it also means the access control system needs to be planned carefully. Fire alarm connections, emergency release devices, and local requirements may affect the installation. 

Electric Strikes: When Existing Hardware Matters 

Electric strikes are often useful when a commercial door already has a mechanical lock or panic hardware that you want to keep using. 

The Mechanical Lock Stays in Place 

Instead of replacing the entire lock, an electric strike replaces the standard strike plate in the frame. Authorized access releases the strike, allowing the existing latch to pass through. This setup can work well for offices, retail spaces, apartment buildings, and other commercial properties where controlled entry is needed without changing the entire door hardware. 

Existing Doors Can Be Easier to Upgrade 

Electric strikes can be installed on many existing doors and can connect with access control systems, intercoms, and other entry devices. That makes them worth considering when you already like the way the door operates mechanically and simply want to add electronic access. 

Magnetic Locks vs Electric Strikes: What Is the Difference? 

The biggest difference comes down to how each system secures the door. 

Feature	Magnetic Lock	Electric Strike
Locking method	Electromagnetic force	Mechanical latch controlled electronically
Works with existing mechanical lock	Usually not required	Yes
Main locking components	Magnet and armature	Strike and existing lock/latch
Common access methods	Card reader, keypad, exit device	Card reader, keypad, intercom, remote release
Power failure behavior	Fail-safe by design	Can be fail-safe or fail-secure depending on model
Glass-door applications	Often useful	Depends on the door and frame
Mechanical latch	Not required for locking	Still used
Existing-door upgrades	Can be suitable	Often useful for retrofits

Electric strikes are available in different configurations, including fail-safe and fail-secure models. Fail-safe means the lock releases when power is removed, while fail-secure keeps the secure side locked when power is removed. 

Which One Works Better With High-Traffic Doors? 

Busy commercial entrances need hardware that can handle frequent use without making entry frustrating for employees or authorized visitors.  

Electric strikes can work with existing cylindrical locks, mortise locks, and panic hardware depending on the application and model. Some products are specifically designed for commercial traffic and access control. 

Magnetic locks have fewer moving parts because the locking force comes from the magnet and armature rather than a mechanical latch. Some commercial models are designed for high-use applications and integrate with card readers, keypads, and other access systems. 

Traffic alone should not decide the hardware. Door type, frame construction, exit requirements, security needs, and the existing lock all matter. 

What About Emergency Exit Requirements? 

Commercial door security cannot be planned around entry alone. People inside the building also need a safe and practical way to exit. Magnetic locks release when power is removed, while electric strikes can have different power-loss configurations. 

Egress Must Be Part of the Design 

Fire alarms, emergency release devices, panic hardware, and local building requirements can affect which locking arrangement is appropriate. Never choose a commercial access control lock based only on security or price. Qualified door professional should review the complete opening and make sure the proposed hardware works with the required egress setup. 

Which Option Is Easier to Add to an Existing Door? 

Existing hardware often determines the answer. Electric strikes can be a practical choice when the current lock or panic hardware can work with the strike. ASSA ABLOY notes that electric strikes can be used to upgrade existing doors and integrate with modern access control systems. 

Magnetic locks can offer a different installation approach when the door does not have suitable mechanical locking hardware or when the opening is better suited to surface-mounted access control. The door should be inspected before hardware is ordered. Frame type, door material, lock preparation, swing direction, and available mounting space can all affect the installation. 

What Should You Consider Before Choosing? 

No single locking system fits every commercial door. Start with the way the entrance is actually used instead of choosing hardware based on appearance or popularity. 

Consider these points: 

• Door type: Glass, aluminum, steel, wood, and storefront doors may require different hardware. 

• Existing lock: Existing mechanical hardware may make an electric strike more practical. 

• Access control: Card readers, keypads, intercoms, and remote release systems need compatible hardware. 

• Traffic: Busy entrances need hardware designed for frequent operation. 

• Security: Consider how the door should remain secure during normal operation and power loss. 

• Egress: Emergency exit requirements must be considered before installation. 

• Maintenance: Choose equipment that can be serviced and supported over time. 

Engaging note: The most expensive locking system is not automatically the right one. Good commercial door security starts with matching the hardware to the opening. 

Magnetic Lock or Electric Strike: Which One Should You Choose? 

The answer depends on the door and what you need the access control system to accomplish. 

Magnetic locks may make sense when: 

• The door design suits surface-mounted magnetic hardware. 

• Electronic access needs to control the entire locking function. 

• The application allows the required fail-safe arrangement. 

• The opening has suitable space for the magnet and armature. 

Electric strikes may make sense when: 

• The existing mechanical lock should remain in use. 

• Access control needs to release the latch electronically. 

• The door already uses compatible panic or lock hardware. 

• You want to upgrade an existing opening without replacing the entire locking system. 

Neither option should be selected from a product description alone. The condition and design of the commercial door should guide the decision. 

Final Thoughts: Get the Right Commercial Door Hardware 

Commercial access control works best when the locking hardware, door, frame, access system, and emergency requirements all work together. Magnetic locks can provide strong electronic control for suitable openings, while electric strikes can add electronic access without replacing the existing mechanical locking system.
