Therefore, it is important that you understand how a magnetic door lock functions and the methods for safely bypassing them. In this article we will provide an overview of how magnetic door locks work and provide detailed instructions on how to bypass them in a safe manner.

Overview of Magnetic Door Locks

Magnetic door locks are a popular way to secure a door, as they are easy to install and don’t require complex wiring. Magnetic door locks work by using an electromagnet and an armature plate. When the magnet is engaged, it pulls the armature plate into it, locking the door. In this article, we will discuss how to bypass a magnetic door lock in order to gain entry into a room.

How Magnetic Door Locks Work

Magnetic door locks are widely used in commercial and residential applications to provide maximum security without the need for a key. Commonly found on exterior doors, magnetic door locks use an electromagnet encased in metal to open and close when activated with the proper transmitter. Installed inside the doorframe, the lock lever contacts an armature plate when the door is closed. When power is delivered to the magnet’s coil, it creates an electromagnet, drawing or pushing the armature plate into contact with the latch, effectively locking or unlocking the door. To ensure a strong holding force when locking your magnetic door lock, all components must fit snugly between the frame and latch head within its casing. The alignment of these parts depends on the striking rail and latch head you select for your application and must cover back any materials you’re dealing with (e.g., different metals can interact differently with magnets). Additionally, you may need extra features such as an indicator to inform users that they’re properly engaged (or warning if they are not). Some higher end models even offer access control systems that require entry using user-specific code or card keys for added security measure.

Advantages of Magnetic Door Locks

Magnetic door locks offer numerous advantages for today’s user that are not available with traditional methods of locking doors. Magnetic door locks provide superior security, increased control and ease of access. Here are just a few of the advantages that can be enjoyed when installing magnetic door locks.

Security: One of the primary benefits of having a magnetic lock is the heightened security they offer. With no visible signs of entry or exit points, burglars and potential intruders cannot easily tell if an area is secured or not. Magnetic door locks also give users the ability to choose who can enter and leave a room by granting or denying access with remote keys or jammers, making it harder for unauthorized personnel to gain access to the building.

Control: Magnetic door locks allow for complete control over who enters and exits an area. These systems allow users to keep track of who was in what areas at anytime by using console systems that indicate which individuals have gained entry into certain areas along with logging in activity such as when people open doors, make adjustments to settings, backup data etc.

Ease Of Access: Magnetic door locks offer convenience by making it easier to get in and out while still maintaining high levels of security since there is no need for pins, keys or passcodes which take time away from productivity throughout the day when you are entering and exiting different areas as you go about your daily tasks. Additionally, if you ever forget your key or access card you can use an override system that allows temporary access while keeping unauthorized persons locked out at all times.

Bypassing a Magnetic Door Lock

Bypassing a Magnetic Door Lock is a skill that can be incredibly valuable for anyone seeking to gain access to a restricted area. This technique, known as the ‘bumping technique’, is often used by security professionals and burglars alike to gain access to restricted areas, and it’s important to understand the basics of this method. In this article, we will discuss the different ways of using the bumping technique to bypass a magnetic door lock as well as the advantages and disadvantages of each method.

Using a Credit Card

Using a credit card is an effective way to bypass a magnetic door lock. For this method to work, the lock should not be too modern as modern locks are easier to break using other forms of technology. However, basic magnetic door locks can be easily opened using a credit card.

To begin, the person needs to insert the edge of the card into the gap between the frame and door. The goal is to keep pushing it in until it reaches the latch mechanism inside. If done correctly, when enough pressure is applied, it will trigger the latch and allow for entry into the room. One should keep in mind that it’s better to use a plastic ID or debit card as metal ones can cause damage to the locking system. It may take several tries with different cards before being able to bypass the magnetic door lock so patience is key when attempting this method.

Using a Slim Jim

To bypass a magnetic door lock using a Slim Jim, you will need to insert the Slim Jim in between the edge of the door seal and the frame. Slowly and gently slide it down until it reaches just under the internal deadlatch level. By wiggling your tool slightly, you should be able to pull back on the deadlatch if it is flush with or extending outward from the doorjamb or frame. Make sure to keep a steady grip on the Slim Jim so that you don’t accidentally drop it or cause any damage to other components of your lock. Once you have successfully pulled back on the deadlatch, turn your knob or key and open up your door.

It’s important to remember that bypassing a magnetic lock can be tricky and requires some experience with tools like a Slim Jim. If you have doubts about using one, consult with a locksmith who can provide assistance in selecting and using an appropriate tool for bypassing your magnetic door lock safely and efficiently.

Using a Lock Pick Set

Using a lock pick set is a great way to bypass a magnetic door lock without damaging the door or the lock. It is usually best to use a typical pin and tumbler lock pick set, but there are also specialized sets designed specifically for bypassing magnetic locks. To open the door using this method, begin by inserting the tension wrench into the top of the keyhole and turning it ever so slightly in an effort to move the pins inside of the lock. Once you have enough tension, scoop out each pin one at a time with your rake or single pin pick until all of them have been moved out of their designated position. When this happens, if you apply enough pressure to your wrench, you should be able to open the magnetic door lock.


In conclusion, bypassing a magnetic door lock is possible with proper tools and electrical knowledge. However, it should be noted that attempting to bypass any lock without the correct qualifications may end in damaging the lock, confronting security systems and potentially breaking any applicable laws. If you find yourself in a situation where you need to access a restricted area protected by a magnetic door lock, it is best practice to contact an experienced locksmith or security expert to gain access correctly and safely.
