The unlocking expert teaches you theft: it must be locked. This is the key.

Yesterday afternoon, the reporter went to the Jinchenghuacheng Community with the unlocking expert He Shifu. He showed the scene on the scene. In the case of not locking the iron gate, he used the relevant tools to open the security door in 3 seconds.

He said that if the "three-row marble lock" is installed, the iron gate will be locked when going out, and it is still impossible to open the door by technical means. "It must be locked, this is the key." He Shifu stressed that if you ignore this point, even the best lock core is useless.
