Unlocking skills of plum blossom lock

Hello, the opening method of the plum blossom lock is as follows:

Although the plum blossom lock is not a high-level lock and its accuracy is not high, it is sometimes really difficult to open it without the unlocking tool. Especially those novices.

When unlocking, first retract the sleeve counterclockwise in front of the tool, and then push the push pin on the handle down to the bottom, so that the steel head is flush with the tool mouth. Then gently put the tool into the lock hole and hold it gently to dislocate the lock core.

Shake the tool left and right and move it into the lock core, so that the tool has seven thin steel plates, each of which is aimed at a marble. After the marble is misplaced here, the upper bead (that is, the marble we see) is long or short, and the steel plate on the tool is slightly loose, and it will shrink to a suitable position when it touches the marble.

We can see that the steel sheet on the 7-character head on the tool sleeve is high or low, forming the tooth shape of the marble. At this time, you don't have to hold it. You can try to twist the tool a little. Until the rotary lock cylinder is opened, tighten the sleeve in front of the tool clockwise, and then the tool can be used as a key. If you want to make a key, you can use a ruler for measuring marbles and measure the length of marbles on a tool.

In some cases, when opening the emergency lock of the electronic safe, it is necessary to remove the sleeve in front of the tool before inserting it into the hole to open it. Otherwise, the tool can't reach the lock cylinder marble, and naturally it can't be unlocked smoothly. This tool is easy to use and locks quickly.
