1. Try to choose electronic door locks with B-level or over-B key cylinders. Now there are electronic door locks with C-level cylinders on the market. The higher the lock core level, the longer it takes to be cracked. Grades beyond B and above are currently not found in the national standards. These standards are mainly standards formulated by some enterprises themselves, and the national standards are needed to unify the standards in the later stage. But for now, it’s okay to buy a higher grade.
2. The location of the physical keyhole should be on the front of the electronic door lock as far as possible, rather than at the bottom. The physical keyhole at the bottom may be a fake lock cylinder, and the anti-theft level is average.
3. If you are worried about leaving fingerprints and are guessed by criminals, you can choose an electronic door lock with a random password. The random password function is to randomly present a few digits when unlocking, you press them and then enter the correct password, so that the fingerprints left are more uniform and not easy to guess. If you are worried about being seen by the person next to you when you enter the password, you can choose an electronic door lock with a virtual password function. The entered string of numbers only needs to contain the correct combination of codes. Regardless of whether the correct combination of codes is at the beginning, in the middle or at the end, the door can be opened, so that it is not so easy for the other party to write down such a long string of numbers and fingerprints. The distribution is also very uniform.
4. Before buying an electronic door lock, you must communicate with customer service. Each smart door lock may have restrictions on the doors that can be installed, whether it is material or size. So before you buy, you must not pretend to place an order blindly, and cooperate with customer service to collect all kinds of information before you can buy a suitable smart door lock.
