When purchasing a smart door lock, it’s crucial to consider several factors to ensure the utmost security. The primary purpose of a fingerprint smart lock is theft prevention, and the lock cylinder plays a vital role in achieving this goal. The key factor to examine is the compatibility between the smart lock and its accompanying key. The C-grade lock cylinder is notable for its dual holes and multiple precision teeth, indicating a high level of accuracy.

Opting for a high-security level lock cylinder ensures precise functionality.If the key’s precision is compromised, the overall security will be severely compromised as well. In some cases, it may even result in an inability to open the door. It is essential to prioritize accuracy over marketing claims, as many locks labeled as C-grade fail to meet even the standards of an A-grade lock.

Furthermore, apart from the security level of the lock cylinder, it is important to consider the presence of a lock core protection mechanism. While mechanical lock cylinders are common in today’s smart locks, the lock core should not be exposed. The lock core cover effectively shields the internal structure and should incorporate anti-drill bolts and anti-drilling components to prevent easy penetration by professional lock pickers.

In addition, the choice of materials for the lock body is significant. It is widely known that metals are generally harder than plastics. Although many smart locks emphasize the craftsmanship and materials of the panel, some manufacturers, for cost-saving reasons, reduce the use of metal materials or even eliminate them from the external panel altogether.

A reputable smart home door lock brand should never compromise on the absence of metal. Apart from losing impact resistance and reducing the lifespan of the smart lock, the lack of metal diminishes its ability to provide electromagnetic shielding, consequently affecting its anti-static capabilities. Therefore, it is crucial to avoid purchasing such types of smart locks.

For instance, Kadonio smart locks offer lock cylinders with a minimum level of B+ and can even reach the C-grade level. The keyhole is generally located below the digital front door lock, making it challenging for intruders to manipulate the lock from underneath. Additionally, the 8 series facial recognition smart locks are equipped with protective casings to safeguard the lock cylinder, significantly enhancing home security.

By considering these essential aspects and opting for a trusted brand like Kadonio, you can ensure that your smart lock purchase meets the highest standards of security, durability, and functionality.
