Lock or fortune telling _ Dialogue between lock and fortune telling

What do you mean by matching keys? According to the key or lock?

Matching keys means that keys are lost or damaged. You should ask the master who repaired the lock to make a key and make a new key according to the spare key. Matching keys are usually based on keys. The main materials for making keys are copper, aluminum and other metals.

When matching keys, it should be noted that some key blanks are made of metal, but they are really inferior. Before long, the teeth will be worn out. A good metal blank gives off a crisp metal sound, while a poor metal blank gives off a dull sound similar to the collision between plastic and hard desktop.

Extended data

Match the key according to the picture.

Generally, the keys of civil locks are configured through network pictures, and the finished products are configured according to the approximate outline, depth and height of the picture keys and the subjective experience of the locksmith master, with an accuracy rate of less than 100%. At present, there is also a "two-in-one" reading tool for most cars at home and abroad, which can read accurate data, open doors and even make the same keys as the original ones without unlocking. However, this tool is generally limited to regular locksmiths and professionals, and it is illegal to sell it online.

Generally speaking, the lower the level, the easier it is to configure. For example, the key of class A lock is flat, and there is only a single-sided single-row marble groove, which is easy to be carved by pictures. Locks that can be opened with tinfoil tools are all Class A and Class B locks, such as cross, single row, double row and curved pin locks, which are easy to open with tinfoil tools. Class C lock is a kind of key, which can't be opened because of its blade and idling characteristics. It is also a relatively safe anti-theft lock core at present.
