The safety of stainless steel lock can be measured from two aspects:

  1. To resist vandalism, pranks, deliberate prying, drilling and other violent destruction. At present, the mechanical strength of mechanical locks and electronic door locks can meet the requirements.
    2. The prevention technology is turned on. The keyed alike padlock has a poor ability to prevent it from turning on. Regardless of the structure of the mechanical lock, it can be opened by other means. The key can be copied is a big security risk. In the electronic door lock, the magnetic card has no password restriction, and its key card is easy to be copied. IC cards and radio frequency cards have completely solved the problem of preventing technology opening.
