Change locks revolutionary national high-end community real estate popular fingerprint lock

A recent report by the Consumers Association has brought widespread attention to the term "A-level lock." According to the Ministry of Public Security's GAT73-94 standard, "Mechanical Anti-theft Lock," anti-theft locks are categorized into two levels based on their security performance: ordinary protection and advanced protection. The ordinary level is labeled "A," while the advanced level is marked "B." An A-level anti-theft lock must withstand at least one minute of technical unlocking and over 15 minutes of destructive opening. In comparison, B-level locks are considered more secure, as testing shows they can resist forced entry for significantly longer than the average time a thief might spend attempting to break in. Yesterday, reporters learned from property management companies in major cities like Beijing, Guangzhou, Shanghai, and Shenzhen that most high-end residential buildings still use the original door locks installed by developers. These locks, even if basic, often feature a "partial lock" system with two types of keys. This allows homeowners to hand over keys to decorators without needing them to enter the house directly. Once the key is inserted and turned, the lock engages, making it difficult for unauthorized people to access the property. Many owners feel these locks are safe enough and choose not to replace them. According to a property manager in Shanghai, most residents don’t change the locks because the original ones are A-level anti-theft locks, which were commonly used in older buildings. However, some smaller developers still install A-level locks to cut costs. At the Beijing home improvement market, A-level locks can be purchased for just tens of yuan. Their internal mechanisms are simple, featuring small and shallow grooves that make them easier to pick or manipulate. In contrast, B-level locks have more complex structures, such as double-row grooves and irregular patterns on the key, making them harder to bypass. In high-end real estate developments across the country, traditional mechanical locks are being replaced by fingerprint locks. In a newly delivered building near Beijing’s West Third Ring Road, all doors are equipped with Asia Pacific Tianneng fingerprint locks. These smart locks include a fingerprint scanner, a keypad, and an emergency key option. They allow users to unlock the door via fingerprint, password, or physical key. Passwords can be set with up to 12 digits, offering enhanced security. Industry insiders noted that fingerprint locks vary in price, but well-known brands like Asia Pacific Tianneng are commonly used in premium developments. Each unit typically costs between three to four thousand yuan, while even the cheapest models exceed two thousand yuan. As a result, these locks are mainly found in mid-to-high-end housing and are becoming increasingly popular in luxury communities.
