Types Of Door Locks
A lock is basically a device which is instilled in the doors of rooms, cabinets, safes, lockers or drawers for security. The concept of locks is not a new one and so is securing ones objects from theft and robbery.
Historians are not confirmed as to when the first lock was invented, but it is believed that it was invented during the early Egyptian civilization. Today locks are used every where, form our doors to our windows, from cabinets to drawers.
Any place that contains any important item is made secure by keeping it in a place where a lock is installed. Locks are mostly all key able and can only be opened when the right key is inserted into them.
There are many different types of locks available today, out which few common ones are given below:
Padlocks are probably one of the oldest and the most commonly used locks in the world. These locks are not exactly fitted to the doors but are portable and are inserted around a single loop or two loops in order to hold two parts of a gate together.
A padlock consists of a main body to which a U shaped shackle is attached and a locking mechanism. The shackles remains firmly attached to one end of the body while is at the loose on the other end.
When a padlock is in an unlocked position the shackle at one end swings freely, but when locked, the shackle form the free end is inserted into a hole made below on the body.
How To Break Into A Door?
- Breaking A Door Lock
Something that happens to every other person at least once or twice in life is forgetting keys and realizing it only after locking the door, or when some how you have lost the keys while being in a hurry, dropped them somewhere and don't know where.
Only when the right key is inserted the shackle from one end can be released again.
So this way when the padlock is in an unlocked position it is inserted through the loop form the free end of the shackle and when inserted the free end is pressed downwards so that it gets firmly inserted into a hole and can only be unlocked when the right key is inserted.
Padlocks are reliable but not as much as other locks of today. They can easily be broken by using a hammer or anything hard. But they can be used along other locks inserted or fitted on the door for higher security.
Dead bolts are another common type of lock. It mostly used on the doors of bedrooms and windows along with other locks.
A dead bolt has a key cylinder on the outside of the door and a handle on the inside or it can have key cylinders on both the inside and the outside of the door but a handle only on the inside. Such dead bolts provide much more security and are known as the double cylinder dead bolts.
Dead bolts are very reliable as breaking through them is not easy. As they don’t have a handle on the outside only the right key can open the key from the outside.
Knob locks are more commonly used on the doors of interior rooms of a house or a building.
A knob lock consists of a knob on both the outside and the inside of the door with the knob on the outside the door bearing a key cylinder and the inside knob bearing a press button for locking. Knob locks should never be used for the external doors as breaking through them is easy.
But for the internal doors they are the best choice. A person can press the button and lock the door from the inside and can easily open from the inside by just simply twisting the knob. The lock can also be opened from the outside by using the right key.
Lever- handle locks
Lever handle locks are another type of locks that are used for the doors of the rooms.
They have a large lever like handle on the inside and the outside of the door.
A key cylinder is attached on both the sides.
Cam locks are commonly used on cabinets and drawers.
They have a very simple mechanism with a key cylinder from the outside.
One has just has to insert the key and twist. An extra handle must be attached to the drawer or the cabinet for pulling it.
