Replace the battery of the safe, find the external power box, install the battery and find the external socket, and you can open it normally.
Shake the body of the safe. The general way to open the safe is to insert the key and add the password to open it. If the password is absolutely correct, it must be that there is something wrong with the stop valve inside, which has rusted because of long-term use. If you want to solve it, it's easy. Just lift the corner of the safe and shake it, and you can rub the stop valve and the key. Try inserting the key again several times to open it.
Dial the password scale accurately. At present, most of the safes used in the family are mechanical password lock safes, which require users to turn the password. If this situation cannot be opened, the safe will need to be demolished and overhauled. There is a technical deviation in the cipher dial. For example, the password you dialed is 000, but it is actually 1 1 1, so it can't be opened. This requires maintenance by the manufacturer.
The Historical Origin of Safe
The history of the safe can be traced back to the Middle Ages. In medieval paintings, you can occasionally see a wooden cabinet filled with gold, silver and jewels, which is the prototype of a modern safe. This is a wooden safe, which contains gold, silver and jewels. It is located in Louis XV in the18th century, and is copied by the famous French safe manufacturer FICHE-BAUCHE.
This kind of safe looks like furniture, and has no special lock, so its security is low. Until the beginning of19th century 200 years ago, with the growth of social economy, the safe industry began to develop, and specialized lock manufacturers appeared in Europe. 18 18, the British chubo company was established. 1825, French FICHE-BAUCHE company was established, and these manufacturers began to manufacture safes.
