Three types of door locks

2020-05-14


Design


Lock manufacturers can make locking systems to meet industry specifications or individual specifications. They offer standard products that they produce en mass as well as custom-made ones.


The decision of what kind and what size of lock to choose for any given application can be quite tricky. Luckily, any good lock supplier will be able to assist a customer in this regard. When helping a customer find the right products, lock manufacturers will consider whether or not their application requires high security, whether or not their application requires portability, whether a lock must be durable, how many people will be accessing the lock, how often the lock will be used.



Types


Locks are divided into three main categories: mechanical, electronic, and biometric.

Mechanical Locks


Mechanical locks are those most commonly seen on the doors and door frames of residential and commercial buildings, as well as on interior doors, like those to a bathroom, bedroom or office. They are made of metal and either opened using a combination or a key.



Electronic Locks


Electronic locks and electronic locks systems do not use keys, but rather plastic magnetized cards or access passwords or codes. In order to open a bolted door or safe, authorized users must put the keycard in a card reader, located on the door, or punch in the correct password or code into a mounted keypad. After authorized personnel closes a door with this type of lock, the door will automatically re-lock, as a computer chip in the electronic key has programmed them to do. Workplaces with locks like these most commonly include those with high security levels, high turnover rates or staff with constantly shifting authorizations.



Biometric Locks


Biometric locks are the most comprehensive security lock of all lock types. They vary, but typically, they require voice recognition, a retinal scan, or a fingerprint scan to open. Biometric locks are highly advanced and very secure. It is no surprise, then, that they are also very expensive. Given their nature and price tag, they are mainly employed by government agencies and other businesses, like banks, that allow extremely limited access to certain facility spaces.



Other Locks


Within these categories are countless other lock types, such as padlocks, cylinder locks, mortise locks, deadbolts, spring bolt locks, warded locks, cam locks, vending machine locks, luggage locks, bike locks, child safety locks, window locks, combination locks, lever tumbler locks, disc tumbler locks, wafer tumbler locks, sidebar locks, cable locks, magnetic key locks, and more.


Mortise locks are incredibly hard to break or pick. As such, they are the best choice for outer door lock security applications, though they cost quite a bit to install.


Cylinder locks work well for applications that require less security. While less secure than mortise locks, users can change cylinder locks easily. Also, these door locks are much less expensive.


Deadbolts feature a heavy square bolt or a round-profiled rod piece, made of solid titanium or steel, that users insert into a door frame to hold it shut.


Spring bolt locks are very similar to deadbolts. The main difference between the two security locks is the fact that deadbolts can only move into the open position when some rotates the key. Spring bolts, on the other hand, will open if you pressure the bolt, since it holds the bolt in place using a spring.


Lever tumbler locks hold a bolt locked in place with the help of tumblers. When the bolt is locked, the door is locked. When users lift the tumbler, the bolt is no longer trapped and they can move it out of its spot in order to unlock the lock.


Magnetic key locks are one of the newest lock mechanism types. This locking system, which is growing in popularity, contains spring-loaded pins, which magnetically repel when a user inserts the key.


Things to Consider

To get the peace of mind and security you seek, you need to work with a lock supplier you can trust and who has the right services for you.
