Whether a smart door lock is safe or not is actually a test of whether the lock cylinder is safe. Therefore, the lock cylinder is the core of a smart door lock. With a lock cylinder with a low security level, safety is naturally out of the question.

Except for wrought iron doors, fence doors, double lock doors, glass security doors, bull head lock doors, and hidden doors, doors cannot be installed. The thickness of the body must also meet the corresponding requirements, as follows:

Then, it is necessary to measure the key data of door thickness and guide plate size. Just follow the measurement method below and send it to customer service. Because the guide piece in your home is not a standard size, the manufacturer will customize a guide piece according to the size, so data measurement is still very important.
