Customers often only pay attention to the appearance and steel plates of anti-theft doors when purchasing, neglecting the "heart" of the anti-theft door - the lock. The majority of dealers, when promoting their products, do not mention the lock to reporters, but rather emphasize how thick the steel plate is and how favorable the price is, without reminding customers to pay attention to the lock.
