Combination locks are commonly used locks in modern households. They can be opened with a series of numbers or symbols. There are two main types of combination locks, one is a keyboard combination lock, and the other is a dial-type mechanical combination lock. Let’s take a look at these two types of locks and their purchasing tips.
1. Classification

Although new electronic anti-theft locks emerge in an endless stream, keyboard-type electronic password anti-theft locks are still the mainstream in the market, and are often used as an auxiliary input method for other types of anti-theft locks.
2. Dial-type mechanical code lock
The dial-type code lock is similar to the dial of an old telephone. Start from the starting point of the dial and turn the dial clockwise to a certain digit. number, then return to the starting point and enter a password. Repeat this until the last digit of the code is entered, and then turn the dial counterclockwise from the starting point to unlock. When unlocking, the interior has been reset, so after the dial returns to the starting point to close the lock, you must re-enter the password to unlock, and there is no need to consider the internal reset issue.
