With a gentle press, the barrier gate opened in response. On online platforms, the sales of "universal" remote controls priced at tens of yuan are astonishing, and palm sized devices are promoted as "unobstructed" artifacts. In the merchant demonstration video, whether it's the community gate, parking lot railing, or shop rolling shutter door, simply press the device a few times to make it obediently "obedient". The principle behind this is not complicated. Most barrier gates use wireless remote control with a fixed frequency, while a universal remote control only needs to copy and scan the frequency, just like having a universal key to open a generic lock. What is even more shocking is the openness of sales. On mainstream e-commerce platforms, the "universal remote control" is openly labeled as "universal for barrier gates" and "special for rolling shutter doors", with monthly sales often exceeding a thousand pieces. In the comment section, "Copying security remote control, parking without payment", "Entering the community gate casually" and other "usage experiences" are prominently displayed. When tools that break rules become products with clear prices, the mentality of luck is amplified by merchants' "convenience" promotion, and the safety barrier has already appeared. Although small, the barrier gate is a safe line of defense that not only safeguards the living safety of residents and the property safety of units, but also carries the basic trust of society in rules and order. The universal remote control renders this line of defense virtually useless, directly eroding the sense of security of the owners, disrupting the charging order of the parking lot, and even providing an opportunity for criminals to infiltrate the campus and units. A small remote control pries the foundation of trust in "safety management" in the entire society. The Radio Management Regulations of the People's Republic of China stipulate that the production and sale of radio transmission equipment require model approval, and such unauthorized "universal remote controllers" are clearly illegal products. Why can they be publicly sold on e-commerce platforms? The 'leniency' of platform review cannot be shirked. Faced with blatant violations such as "universal remote control" and "barrier gate cracking", the platform has neither verified product compliance nor blocked dangerous propaganda, actually providing a "stage" for illegal transactions. What needs to be further questioned is the speed of regulatory response. Such products are not new, why have they been repeatedly banned for many years? Is it due to outdated detection technology or insufficient investigation and punishment efforts? The "omnipotence" of remote control precisely exposes the "incompetence" of management. Many residential areas and parking lots still use old fixed frequency barriers and have never updated encryption technology in order to save time. The security guard placed the remote control randomly and even lent it to others, making frequency replication easy. The similar style of throwing the pot management itself is a disregard for safety. To eradicate the chaos of universal remote controls, regulatory authorities must demonstrate "hard measures". For merchants who produce and sell illegal remote controls, we must investigate thoroughly and not only remove the illegal products from the shelves, but also hold them legally responsible; For e-commerce platforms, it is necessary to strengthen the main responsibility, establish a keyword screening mechanism, and ensure that illegal information such as "cracking" and "omnipotence" cannot be hidden. The management should abandon the mentality of 'compromise'. The property management of the community should regularly inspect the safety of the barrier gates and upgrade the equipment in a timely manner. Security personnel should standardize the use of remote controls to avoid frequency leakage. From the encryption upgrade of barriers, to seamless regulatory integration, and to everyone's reverence for rules, only by plugging loopholes in the front can "safe entry and exit" be put into practice from paper.
