Breaking a traditional lock is much easier for thieves to do than you might think. If you are looking for an effective way to protect your house and your other valuable belongings, hidden door locks are a fantastic option for you. Hidden locks can improve the security system for many applications, including:

Even if you use a passcode or pass card security system, anyone can hack your system or guess the password you have set and enter your house with nefarious intentions. 

With more digitized systems, more modern hacking methods are rising. Anyone with hacking skills can predict your password or manufacturer a card to open the door. Therefore, hidden door locks are essential for enhancing your home security.

Mechanism of Hidden Door Locks

The workings of a hidden lock is a relatively lesser-known idea. Therefore, we will help you understand the basic principles here. Most hidden locks involve a magnetic system as those are difficult to find and break. People also call them electromagnetic doors due to the magnetic system. 

The mechanism of these magnets in the hidden locks work in collaboration, each part contributing its own function:

  • Hidden locks contain a magnetic system with two primary parts, including an electromagnet and armature plate. The electromagnet gets attached to the armature plate when you supply it with power. The armature plates are made of metal because magnets only work with metallic surfaces. 
  • Some hidden locks use advanced sensors with them; the sensors help in the detection of unusual people and alert you when someone is at the door. You can install sensors according to your requirement; you can find them on the internet or in hardware stores. Using the sensors, you can enhance your home security system, and it allows you to recognize the person at your door. The electromagnetic door automatically locks the gate after you let a person in.
  • The electromagnet works on electricity; hence, hidden locks require a power supply. You will have to supply power to the lock when you install it. During power outages or when you unlock the door, the power system of the lock remains disconnected.
  • You should not get anxious when an electricity breakage happens as maglocks also include a battery backup. Your hidden locks still work using the stored power in their backup battery during power outages. 
  • You can also use locks that don’t run on electricity. Some hidden locks use magnets and metals. The function of the electromagnets is to get attracted to the sturdy metal and slowly bend the lock to attach to the metal plate. 

You should install hidden locks at your home or office entrance and in your bedroom or where you keep your personal items and valuable belongings. You should also maintain the lock well to ensure your belongings and house’s safety.

What Things Will You Need to Make a Hidden Door Lock?

The conventional door lock requires the following equipment including:

  • A cylinder or the primary lock body

  • An electromagnet that has both a battery backup and a way to get a power supply
  • Sensors according to your need
  • The invisible latch or bolt
  • Two or more metal plates and a box
  • Key fobs
  • Biometric cards
  • Magnetic key
