It is reported that some users are overly focused on the visual appeal of security doors. Today, many households use security doors, and the variety of locks available for these doors is vast, with differing levels of security. If your home's lock is broken or you're looking to replace it, where can you find a reliable service? How do you choose the right door lock? The expert from the Convenience Union is here to share some useful tips to help you make an informed decision.
**Be cautious when choosing an unlocking company**
You often see posters for unlocking services in corridors, especially in older neighborhoods. But how can you tell which ones are genuine and trustworthy? Many people wonder if these companies are truly safe, especially since thieves might have access to similar services. According to the Convenience Union expert, there are indeed many such services, and they all claim to be registered with the Public Security Bureau. "When we arrive at the scene, we always check the homeowner’s ID and proof of ownership. We also bring documents that have been filed with the police department to verify our legitimacy," he said.
**Choosing the right anti-theft door lock cylinder**
What kind of lock core offers better protection against break-ins? According to reports, the market offers three main types of anti-theft door lock cylinders: A-class, B-class, and Super B-class. A-class locks take more than 15 minutes to open through destructive methods and over 1 minute for technical opening. B-class locks require over 30 minutes for destructive entry and more than 5 minutes for technical methods. Super B-class locks can withstand technical opening for over 4 hours.
The expert explained, "You can identify the quality of a lock cylinder by the number of ball bearings inside. Multiple rows of ball bearings are better than single-row designs, and invisible multi-row ball bearings are even more secure." B-class locks are generally more expensive than A-class ones. If you feel your current lock isn't secure enough, consider upgrading to a B-class or Super B-class lock for higher security.
Some users place too much emphasis on the appearance of the door, the thickness of the steel plate, and the price, but this is not the most important factor. The convenience expert emphasized, "The most critical part of a security door is the lock core. Always pay attention to the quality of the lock when making a purchase."
Currently, well-known brands typically use high-quality locks produced by manufacturers approved by the public security department. These products come at a higher cost. However, some small manufacturers offer cheaper options using low-quality locks from untrusted suppliers. These locks often use inferior materials, such as cast iron or imitation steel plates, which can be easily forced open. It’s hard to imagine how such doors could provide real security.
As a consumer seeking unlocking services, the expert advises you to always ask the technician to show their valid identification and registration documents with the police before proceeding. Avoid hiring individuals seen on small posters to prevent potential fraud or theft.
If you want to stay safe and secure, always prioritize the quality of the lock core and choose reputable providers. Don’t let style or price be the only factors in your decision.
