What should I do if I forget the password of the mobile phone password lock?

Make sure the fingerprint lock is powered on, and then walk to the inner panel of the fingerprint lock (the inner panel is the inner part of the fingerprint lock).

Step 2: Insert your fingernails into the gap under the handle and pull out, remove the lid, and then take out the network module.

Step 3: Find the location of the initialization button, press and hold the initialization button for more than 5 seconds, and let go when the fingerprint lock prompts "factory settings have been restored, please modify the management password in time", and the fingerprint lock has been successfully restored to factory settings.

A factory reset will disconnect the fingerprint lock from the gateway, and you will need to manually bind it again. And all the previous fingerprints, passwords, and card information have been erased, and they need to be added again.

The lock of the lockbox cannot be opened, there are 3 ways to unlock it, as follows:

1. Push the password to the opposite direction of the switch, open the flashlight, turn the password disk, and observe the groove of the rotating shaft; After the groove is found, the number of the groove is recorded, and the three cipher disks record the numbers one by one; Get three digits and process the digits bit by bit: add 5 to those less than 5, and subtract 5 from those greater than 5 to get the password.

For example, if the number 823 is obtained in the groove, the box password is 378.

2. Use the appropriate force to pull the password lock switch to the direction of opening with the right hand, slowly rotate the password from the leftmost digit, feel the right hand move slightly, and then come to the second digit, and continue in turn until you find the last number.

3. If it is more convenient for you to go to the place where you buy the box or ask the store, you can ask the store, they generally know the password of the combination lock.

The principle of the combination lock

1. Multi-dial type.

The simplest combination lock, commonly found in low-security bicycle locks, uses multiple dials. There is a recess in the middle of each circle. A shaft in the center of the lock with several protruding teeth to hold the lock ring. When the dial is turned to the correct password combination, the lock can be opened.

This type of lock is the easiest to open. As long as the axle is pulled outward, one of the teeth will tighten the dial more than the others. At this time, the wheel is tightened until a small "click" is heard, indicating that the tooth has entered the correct concave position.

Repeat this step and the lock will soon be opened.

2. Single turntable.

A combination lock used on a padlock can have only one dial. The turntable pushes several balance discs or cams behind it.

It is customary to turn the dial clockwise to the first digit, then counterclockwise, and so on until the last digit. There is usually a recess on the cam, and when the correct password is turned into, you can form a straight line and the lock can be opened.

This combination lock is more secure, but it is not without its drawbacks. For example, the padlock of some combination locks can be used to tighten the lock and then turn the dial until it can no longer be moved, so that the code can be found. There is also a specific relationship between the numbers of some turntable combination locks, which greatly reduces the possibility of password combinations.

Inexpensive combination padlocks can be opened with special linings without the use of a code. The combination lock used on the box is more tightly structured. An experienced locksmith can use the handset to carefully listen to the sound inside the lock while rotating the dial and judge possible codes.
