Popular Locks in market


o secure and safeguard our properties like our house, shops, etc., locks

play a helping hand. In fact, we completely rely on the locking systems in
our house. So, it becomes important for us to choose the appropriate
locking system out of a wide variety available in the market today.

General lock Types
1. Basic Locks:
Most locks available in the hardware stores and other non-specialty
retail shops are basic in design and hence named the ‘basic locks.’
These locks are easily breakable either with brute force attacks or
finesse lifting attacks. These types of locks with no special security
feature are used in mainstream office products such as desks,
cabinets, storage boxes, luggage, etc.

2. Resistant Locks:
Also known as ‘commercial grade locks’, ‘hardened locks’, ‘pick
resistant’. While some of these a legitimately a step up, they offer no
significant protection beyond the ‘basic level’. These locks prevent an
average attacker from easily opening the lock in under five minutes.

3. High Security Locks:
While both a ‘resistant’ lock and ‘high security locks’ are wholly
non-susceptible to zero skill attacks, they perform differently
when set against tact attacks with hidden entry tools. These
employ a mechanism that completely blocks and render nearly
useless most typical lockpicks.

4. Un-pickable Locks:
It is a fact that to compromise an “unpickable lock”, an attacker
must almost certainly attempt acts to gross devastation or
otherwise render the mechanism in an easily detectable

Besides these basic types of locks, there are many different kinds of locks with different security features.

1. Deadbolts:
These locks are installed on external doors and come in three
primary varieties: single, double, and lockable thumb turn. Single
deadbolts use a key cylinder on the outside and a thumb turn on the
inside to open or close the lock.A double cylinder deadbolt uses a key
cylinder on the inside and the outside of the door. These have the
clear disadvantage of always requiring a key to open the door from
the inside if it is locked. A lockable thumb turn features a
thumbturn on the inside that works like a normal single cylinder
deadbolt, except the thumbturn can be locked using a key so it cannot lock or unlock the door.

2. Padlocks:
These are not permanently attached to anything else. These are
portable, free standing and come in a various sizes. Padlocks
come in two varieties: keyed and combination. Combination
locks are opened if the combination of number on them is
entered correctly.

3. Knob Locks:
These are installed in addition to the deadbolts and are used as
the primary source of security for doors. Since the lock
cylinder is in the knob itself, these should not used as the only
lock system on external doors. They can easily be broken off
the door using a hammer or bypassed using pliers.

4. Lever Handle Locks:
In commercial settings, these are used for inner doors. Since
they have a large push down style handle rather than a knob
that, one must grab and turn, so they are insecure and easy to
break than knob locks. These can be easily broken with the
torque attacks.

5. Cam Locks:
These locks come in several different lengths and can use a variety of
“cams” to interface with another locking mechanism. There is a very
large variety of cam options, and can rotate clockwise or counterclockwise and the amount of rotation can be limited to 90 or 180
degrees. These locks are mostly used in filing cabinets, mailboxes and
lower security OEM applications.

6. Furniture Locks:

This category includes locks for cabinet, desk, and sliding door.
There are two primary styles of furniture lock, bolt style and push
button style. Bolt style locks are found on desks, cabinets, and
drawers, although they are also used in a wide variety of other
devices. Push button style locks have a rod that comes out at the
back of the lock that is used to secure things in place. When the lock
is unlocked it pops out retracting the rod into the lock body. The
device is then re-locked by pushing the lock back into its shell.
Furniture locks can be installed onto existing hardware that may not already have a lock installed.

7. Other Locks:
There are many other lock likes Rim Latch locks, Jimmy
proof deadbolts, T-handle locks, European locks providing
better security features.
