These two types of locks all have their own advantages and disadvantages when used, among which: it is relatively simple to open with a key lock, but the problem is that the key is easy to lose, and the security is not high; although there is no problem of key loss when opening with a password, However, because most of the combination locks are used to lock smaller objects, its scope of application is narrow, and a small number of locks that can be used to lock larger objects cannot change the password. The safety performance is reduced, and some locks that can change the password have a structure that separates the password card from the password wheel and then installs it. When changing the password, the password card is removed from the password wheel and then reinstalled on the password wheel. other positions, so that the code card is easy to be damaged and lost after being removed and changed many times
