History about locks and keys



History about locks and keys - Since the beginning of mankind people have the need to protect what she felt. You begin the entrance of the caves with stones; Later, his gold and jewels were hidden in the ground.

Then they discovered the locks. They were first made of wood and rope. They served the purpose well, even if they are not so well trained. There are many historical proof that the use of locks attests long before we can imagine. Even in the Bible (Old Testament Book of Judges) have frequent mention of locks and keys.

Types

In modern society, we have keys and locks for everything: home, office, car, bike. We even have more than one key at the same building; Keys and locks are part of our daily lives that we ignore (or maybe just do when the key is too heavy to be placed in the bag).

But there is a lot of thought, if we choose the type of lock or the key type. We are basically talking about mechanical locks (based on key mechanical activation) electromechanical Locks (maybe both the mechanical or electrical operation, but more often is the key with the numeric keys that must be pressed, replaced) and electric locks (by a key card activated with a corresponding code set to be read by a card reader, which is controlled by an automatic exchange or a local processor).

How do you pick the lock?
It's not as complicated as we think, but not so easy as it seems in many films. Some say it requires both art and science. Must have good knowledge of the locking mechanism and a little practice.

First, we have to insert a key into the lock voltage (for example, a screwdriver) and with slight pressure, rotate the cap (cylinder lock), as the button would (we need to understand what are the address normal turned the key). This will contribute to a small square between the locking bolt (in the castle found). Then we need to raise put a crowbar (like the right button when inserted into the lock). Do this and we continue to apply pressure on the collet clicks softly (using pins, if they fall into the right position) and the lock is unlocked.

For unsophisticated lock, we can use a metal fork lock as an option. But professional locksmiths have adequate tools box collection. Basically, it consists of a torque wrench (different shapes and sizes) and various options (long pieces of metal, the curve at one end). Some may use a weapon of electric sampling (it contains large pieces of metal and when he grow up vibrate the pins and unlock).

Re inhibit input

The settlement process again easily (a few minutes) and should not be confused with the process of replacing a lock. In fact, it is the removal of the lock cylinder and the replacement of all old new locking pins on the new password match. The cylinder is then installed in the castle!

For example, if a family member loses the house key, can be assumed that a thief. We must immediately return the key lock of the house, to prevent theft. It costs time and money, but we are able to save a lot of stress. The same procedure is recommended when moving to a new house / apartment.

Best of the castle, the more difficult it is to break for a thief!
