The protective performance of mechanical locks is mainly reflected in the following three aspects:
1. Difficulty of Picking
Mechanical locks have a simple internal key structure, making them difficult to pick. The more complex the mechanical structure, the more difficult it is to open. Furthermore, mechanical locks generally only have one method of unlocking; usually, only the key and lock cylinder can be used to manipulate the lock body.
2. Anti-Pry Performance
Most mechanical locks are made of high-strength materials such as iron ore and alloys, using a large amount of steel, which can resist open attacks such as picking with burglar bars.
3. Drill Resistance
The keyhole, lock cylinder, and titanium alloy parts of mechanical locks undergo special treatment, making them resistant to attacks from drilling tools such as electric drills and hand drills.
