The locks we are familiar with can be divided into traditional mechanical locks and new types of electronic door locks. The construction of these two types of door locks is different.

In other articles, I believe you have seen enough about the traditional mechanical lock structure. As a professional manufacturer of electronic door locks, today Signstek will focus on the anatomy of electronic door locks.

In the electronic door lock, according to the different unlocking methods, it can also be divided into door knobs, door handles and deadbolt locks. Understanding the different parts of these several door locks will be of great help to you in the process of installing the door locks, and can also help you solve some minor glitches of the door locks.
