The magnet doesn't make the lock move: Every lock will work differently, but it's typically friction that causes this problem. If a piece of your lock is supposed to move, be sure it can move easily. If it's attached too tightly, your magnet may not be able to move it.
Most dead bolt type locks lock over center, so a magnet can't pull it out of the locked position. Regular house door locks have a pin that prevents the catch from opening unless the knob is turned. A primitive bolt might be drawn open by a magnet, and there are lots of cabinet magnetic actuated locking mechanisms.
For example, magnetic locks work well on interior doors where security isn't a huge concern if the power goes out and the door unlocks. The benefits of magnetic locks include: Strength. The average magnetic lock can withstand up to 1200 pounds of force.
Magnetic locks, commonly known as maglocks, require constant availability of power to operate. A magnetic lock comprises electromagnetic and armature plates. Thus, electromagnetic locks are reliable and provide maximum security for the users. They are commonly used in hotels, offices, and residential facilities.
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

Each key has a complex rounded shape, this coupled with the magnetic element makes it an extremely hard lock to pick. The only way to gain access to the door would be for the key to be cloned, and in that case, a master locksmith would need to get their hands on the original key.
Fail-Safe vs Fail-Secure Openings
Maglocks require constant power to stay locked, making them fail-safe. That could lead to an unsecured opening in the event of a power outage. On the other hand, fail-secure locking functions require power to unlock a door.
Master Keys Set. Occasionally, someone will want the locks they use in their institution, organization etc. to have “mastered” locks. This means that although all the individual locks have individual keys, there's also a “master” key that will open them all.
Lock picking is the first and best method to unlock a deadbolt without a key. It is a popular choice for those who want to avoid damaging their door or lock. Lock picking is an easy skill to learn—the basics required to pick a standard pin tumbler deadbolt can be cultivated within 10 minutes.
CR's take: The Medeco Maxum 11TR503-19 is the strongest deadbolt across all of our lock categories. It's top-notch for drilling, withstands kick-ins very well, and is designed in a way that makes it quite difficult to pick.
Deadbolts, however, are still vulnerable to lock picking. Pin and tumbler locks are the most common designs in use today. These locks use a series of small, spring-loaded pins to keep the cylinder from turning.
This means that when the power fails or is interrupted, the magnet releases and people can freely use the opening. Because magnetic locks secure a door from both the egress and ingress side, they are also required to be integrated into the building's fire alarm, automatic fire detection, or sprinkler systems.
Closed Shackle Padlocks
This is a bolt cutter-proof lock by design. By further shielding the shackle on both sides, it is extremely difficult for someone to cut through with either a bolt cutter—not enough room to grip and exert force—or an angle grinder—not enough exposed parts.
One of the most popular pick-resistant locks is the Medeco. The pin tumblers in this lock must not only be raised to a certain level, they must be turned right or left or not turned at all in order to allow the key to turn.
Some pin-tumbler locks have modified pins that make picking more difficult. In the most common variation, the upper pins have a mushroom-shaped head. This odd shape causes the plug to shift early, before you have actually pushed the top pin all the way up. This makes it more difficult to put the pins in position.
Electromagnets can be stronger than the permanent magnet as we can control the strength of an electromagnet by the amount of electricity which we pass through them. We can make electromagnets that are 1000 times stronger than permanent magnets.
The bigger the mil, the thicker and stronger the magnet will be.
By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.
Most modern storage devices like SD cards, thumb drives and SSDs are essentially immune to magnetic fields. In fact, there's nothing magnetic in flash memory, so for all intents and purposes, a magnet won't affect it at all.
Magnets can damage your electronics
Strong magnetic fields of neodymium magnets can damage certain magnetic media such as credit cards, magnetic I.D. cards, and legacy media such as cassette tapes, and videotapes. They can also cause damage to TVs and computer monitors.
Some magnets can be made weaker because of their surroundings. Heat and radiation from electrical devices such as microwave ovens, wireless routers and computers can affect the strength of a magnet. Common fridge magnets can be made weaker from repeated exposure to heat if they are close to the stove or oven.
