When choosing an entrance door lock, you should consider the following key factors to ensure that it is both safe and practical:
Door opening and closing direction and door frame size: First of all, make sure that the lock is in the same direction as your own door, so that it is easy to use. For door frame sizes, in general, ball locks and handle locks cannot be installed on doors less than 90 mm. If the width of the skeleton around the door is more than 90 mm and less than 100 mm, the ordinary ball lock and 60 mm deadbolt should be selected; Above 100mm, you can choose a lock with a large cover, that is, a 70mm deadbolt.
Material and wear resistance: In terms of material, pure copper locks are a better choice because of their polishing and frosting treatment, natural color and heavy feel. Stainless steel locks are significantly lighter. The sound of brass lated locks opening is dull, while the sound of stainless steel locks is crisp.
Plating and aesthetics: The plating of the door lock is related to the overall appearance of the room, and a good door lock protective layer is not easy to be oxidized and worn, so you should pay attention to whether the handle will fade when choosing.
Security and stability: The security of smart locks is mainly reflected in the lock cylinder level, fingerprint recognition method, electronic anti-lock function, alarm function, etc. It is recommended to choose a lock cylinder above grade C, a semiconductor fingerprint head, a smart lock that supports electronic anti-lock function and an alarm function.
Installation conditions: Before purchasing a smart door lock, it is necessary to clarify whether the type and size of your door meet the installation requirements. Different materials and types of doors (such as wooden doors, security doors, aluminum alloy doors) have different requirements for the installation of smart locks. In addition, parameters such as the thickness of the door, the length of the lock cylinder, and the spacing of the square rod need to be measured to ensure that the right size smart lock is selected.
Brand and after-sales service: preferably a well-known brand specializing in door locks, because its product technology is more mature, the quality is more stable, and the after-sales installation is more guaranteed.
