What is the principle of how to solve the password lock when the password lock is forgotten

4hw.com.cn: in our daily life, it is inevitable to set various passwords to prevent our privacy from being stolen. The password lock is just one of the simple locks, usually with 3 or 4 digits. What should we do if we forget the password of the password lock? Here are a few tips for unlocking.

The principle of password lock

Multi dial

The simplest password lock, commonly used in low security single car locks, uses multiple dials. There are recesses in the middle of each circle. A shaft in the center of a lock with protruding teeth to hold the paddle. When the dial is turned to the correct password combination, the lock can be opened. This lock is the easiest to open. Many of these locks can be opened without knowing the password at all. Unless its internal components are perfectly built, one tooth will be more taut than the other as long as the shaft is pulled outwards. At this time, the ring is tightened until a small "click" is heard, indicating that the tooth has entered the correct concave position. Repeat this step and you will be able to open the lock soon.

Single turntable

The password lock used on the padlock or box can have only one turntable. The rotary table pushes several balance discs or cams behind it. It is customary to turn the turntable clockwise to the first number and then counter clockwise to the second number when opening this lock, so as to the last number. There is usually a concave position on the cam. When the correct password is turned in, you can form a straight line and the lock can be opened. This kind of password lock is more secure, but it has not all shortcomings. For example, part of the password padlock can tighten the lock head, and then turn the turntable until it can no longer move, so that the password can be found. There is also a specific relationship between the numbers of the turntable password lock, which greatly reduces the possibility of password combination. Cheap password padlocks can be opened with special linings without using passwords. The structure of the password lock used in the box is more strict. An experienced locksmith can use the earpiece to listen carefully to the sound of the cam in the lock while rotating the turntable, and judge the possible password.

Password lock forget password how to do?

First, shine a flashlight on one of the gears of the password lock, and slowly move the gears at the same time. At this time, you should carefully observe that when you turn to a certain position, there will be a gap under the gear, which will generally move a little to the left. Sure enough, when you turn to number 6, there is a small gap under the gear. The second and third gear numbers are also '6'.

To achieve this step, we have succeeded in more than half. Next, we need to remember a formula. According to experts, the number corresponding to the gap is not a password. It needs to 'add 3', 'add 8' or 'subtract 5' on the basis of these numbers. When there are two digits, one digit is reserved. These are three common rules. The reporter tried to 'add 3' to the numbers' 6 ',' 6 'and' 6 'corresponding to the trunk gap to get' 9 ',' 9 'and' 9 '. After pressing the' push 'key, the password lock was opened successfully.

Of course, experts also said that there are some special suitcases, which are not unlocked according to this formula. At this time, we should bear the patience and try slowly. As long as we add the 10 numbers of 0-9, it's really not good. We can reduce them again and open them up 20 times at most. In fact, the effect of adding and subtracting the number of notches from the bottom of the gear is the same, so it can be done up to 10 times, far faster than random test like a headless fly.
