Can a Keycard Security Door Be Opened by Pulling Hard on It?

When it comes to keycard security doors that use an electromagnetic lock, often referred to as a maglock, the common perception is that such doors are impervious to brute force. However, several factors contribute to the potential vulnerability of these doors when subjected to significant pulling force. In this article, we will explore the conditions under which a maglock might yield to a powerful pull.

The Role of the Electromagnet

Electromagnetic locks are designed to hold doors securely in place, often requiring a significant amount of force to overcome the magnetic hold. Despite their robust design, there are situations where a maglock can be compromised. For instance, during a power failure, the electromagnet may lose power and become disengaged, allowing the door to be opened with relative ease. Similarly, if the lock is malfunctioning, the same outcome may occur. In such cases, applying a substantial pulling force could lead to the door opening.

Mechanical Design and Additional Locking Mechanisms

Some keycard security doors incorporate additional locking mechanisms, such as deadbolts or latch bolts. These mechanisms can prevent the door from being pulled open even if the electromagnetic lock is engaged. Therefore, even if the maglock is compromised, the presence of these supplementary locks can enhance the overall security of the door.

Proper Installation and Maintenance

The effectiveness of a maglock is not only determined by the strength of the electromagnetic field but also by the quality of its installation and regular maintenance. If the maglock is not installed correctly or has not been maintained properly, it may be weaker than intended, making it easier to pull the door open. Regular servicing and inspection can ensure that the lock operates at its optimal level.

Force Applied and Real-Life Examples

The amount of force required to pull a door open is crucial. While it may take a considerable amount of force to open the door while the lock is engaged, it is theoretically possible to do so, especially if the lock is not functioning optimally. However, in practice, applying such a force can often result in damage to the door and surrounding structure before the lock gives.

There are instances where such force has been applied successfully. For example, in a true emergency, a strong force might be used as a last resort. One such instance occurred when a 4-wheel drive Bronco was used to hook a cable to a door that needed to be opened to rescue a young girl from a wrecked pickup. This highlights the potential for such doors to be opened through extreme force.

Magnetic locks are incredibly strong, and the force required to break the magnetic bond is substantial. Even though the electromagnetic component is relatively small (about 4 inches by 6 inches), the force necessary to overcome it would be immense and could potentially damage the door and the surrounding structure. Such force would likely destroy the door before breaking the magnetic bond.

If you find yourself in a situation where a maglock-secured door needs to be opened and you have no access to a locksmith, it is advisable to seek professional assistance. Calling someone to open the door ensuring the safety and integrity of the structure is the preferred approach.

When using maglocks, it is important to understand that the door is more likely to fail than the lock itself. Given the mechanical design of modern security doors, the door frame and other components are often the weak points that would give way before the electromagnetic lock is compromised.

While keycard security doors with electromagnetic locks are generally robust and secure, understanding the potential vulnerabilities can help in making informed decisions and taking appropriate measures to enhance security.
