There are many keys, cross, round, crescent, and almost all shapes. However, in general, the material of the key is copper or aluminum-iron alloy, which is easily copied. At present, the better material is steel, and its safety is high.

There are many kinds of lock body materials for household fingerprint locks, for example common materials include iron, steel, stainless steel, zinc alloy and other materials. Under normal circumstances, if the hardness of the lock bar is insufficient due to the limitations of the process and cost, it is often easy to be cut by the pliers and hydraulic pliers.
