The principle of password lock
Multi-dial
The simplest password lock is commonly used in bicycle locks with low security settings, using multiple dials. There is a concave position in the middle of each circle. There are several protruding teeth on a shaft in the center of the lock to jamm the ring. When the dialing passes to the correct password combination, the lock can be opened. This kind of lock is the easiest to open. Many of these locks can be turned on without knowing the password. Unless its internal components are flawless, just pull the axial outward and one of the teeth will be tighter than the others. At this time, the wheel is tightly pulled and twitched until a small "clutter" sound is heard, indicating that the tooth has entered the correct recess. Repeat this step and you can quickly open the lock.
Single Roulette type
The password lock used on padlocks or cassettes can be only one turntable. The turntable pushes several balance discs or cams behind the back. Customary, when you open this lock, turn the turntable clockwise to the first number, then reverse clockwise to the second number, so as to the last number. There are usually concave positions on the cam. When the correct password is entered, the positions are in a straight line and the lock can be opened. This kind of password lock is relatively safe, but it is not without shortcomings. For example, some password padlocks can tighten the lock and turn the dial until it can no longer move, so that the password can be found. There are also specific relationships between the numbers of some rotary dial password locks, which greatly reduces the possibility of password combinations. Cheap password padlocks can be opened with special linings without using passwords. The password lock used on the Siwan is relatively tight. An experienced locksmith can use the earpiece to carefully listen to the sound of the cam inside the lock and judge possible passwords while rotating the turntable. What should I do if I forget my password when I have a password lock?
First shine a strong flashlight on one of the gears of the password lock, and slowly pull the gears. At this time, you need to observe carefully and you will find that when you turn to a certain position, there will be a gap below the gear, which will generally be slightly tilted to the left. Sure enough, when you turn to the number 6, a small gap appears under the gear. The second and third gear numbers are also “6”
If you do this, you will be more than half successful. Next, you need to remember a mantra. According to experts, the number corresponding to the gap is not a password. It is necessary to "add 3&rdquo", &ldquo" add 8&rdquo or "reduce 5&rdquo" on the basis of these numbers. This is three more common rules. The reporter tried to add “6”6”6”6”6” respectively, and get “9”9”9”9, and press the “Push” and the password lock was indeed successfully opened.
Of course, experts also introduced that there are also some special suitcases that are not unlocked according to this mantra. At this time, you have to patiently try it slowly. Just add all the 10 numbers 0 to 9. If it really doesn't work, subtract it again and you can open it at most 20 times. In fact, adding and subtracting the notch number under the gear is the same effect, so it can be done up to 10 times, which is much faster to try like a headless fly.
