Beginner’s Guide to Magnetic Locks – The Good, the Bad, The Installation


Magnetic locks are among the most popular locks these days, especially for glass doors. They’ve become incredibly popular for many applications in recent years, thanks to their strength, reliability, and convenience they provide. 

Nonetheless, these locks are also known to have a few drawbacks that are worth getting familiar with. This piece will cover some of the ins and outs of magnetic locks that you ought to know so you can make an informed decision on your project. 


Magnetic Locks: Types and How They Work 

Magnetic locks, also known as maglocks, function by using electromagnetism to secure doors. Once the lock receives electrical power, it generates a strong magnetic force that connects with a metal plate on the door’s other side, locking or unlocking the door.

The two main types of maglocks are fail-safe and fail-secure locks. Fail-safe locks unlock when power is lost, while fail-secure types remain locked in case of a power outage. These locks are also available in a wide range of designs to choose from based on the intended application. 

Below are some of the merits of magnetic locks, alongside a few demerits worth deliberating on. 


The Good: Pros of Magnetic Locks 

Keyless Access:

Maglocks offer electronic keyless access, allowing for simplified entry using access cards, key fobs, or biometric authentication methods like fingerprint scanning.

Low Maintenance:

These locks require minimal maintenance, as they have no moving parts which could wear down over time.

Strong Holding Force:

Maglocks have an impressive holding force that makes it difficult for intruders to gain unauthorized access. This is among the reasons why many homeowners upgrade to magnetic door locks for safety against unauthorized entry. 

Reduced Wear and Tear on Doors:

Since there’s no physical connection between the lock and door mechanism, magnetic locks minimize strain on the doors themselves, causing less wear and tear.

Ease of Installation: 

Magnetic locks are relatively easy to install and can be fitted without extensive drilling or major modifications to the door structure.


The Bad: Cons of Magnetic Locks

One disadvantage of magnetic locks is that in the event of power outages or system failures, home security can be compromised. As they rely on electricity to function, loss of power could render the locks unusable and automatically unlocked—leaving an area vulnerable. Although some systems come with built-in battery backups, these backup power sources can eventually drain if the outage lasts for a prolonged period.

Another significant drawback to consider is that these locks may not always meet local building codes or fire regulations. Traditional door locks typically allow for doors to open easily from the inside in case of emergencies—an essential feature during fires or other evacuation scenarios.

In contrast, due to their design, maglocks might not provide easy egress unless equipped with an emergency release button or integrated into a comprehensive access control system that automatically unlocks them during emergencies. Thus, before opting for maglocks, it’s crucial to ensure they abide by local regulations and ensure ease of access when needed most.

In a nutshell, some critical drawbacks to consider before installing magnetic door locks include the following: 

  • Power dependency
  • Outage vulnerability
  • Building code compliance
  • Emergency egress

Do Magnetic Locks Suit Your Needs?

In conclusion, magnetic locks offer an array of benefits, including easy installation, keyless access, low maintenance, a strong holding force for safety, and reduced wear on doors. While there are some drawbacks—such as power dependency and potential compliance issues with building codes or emergency egress—many people find that the pros far outweigh the cons. 

To determine if maglocks are the right choice for you, carefully assess your specific security needs, local regulations, and available backup options to ensure you make an informed decision that ultimately enhances your safety and convenience.
