How to open the hole in the wooden door

Generally speaking, locks made according to mechanical principles need to be inserted with keys before they can be opened, such as door locks, bicycle locks, safe locks and so on. In this way, a lock hole is naturally formed, so that the key can be inserted normally, and the size and shape of the lock hole are set for a key that is completely matched with the lock. The keyhole is upgraded from the traditional keyhole. Compared with traditional keyhole, keyhole has been greatly improved in waterproof, anti-corrosion and foreign body prevention. The main reason is that the safety lock hole can minimize the risk of the lock core being pried open.
