locksmiths will tell you that the lock core is the heart of the door lock, and its quality directly affects the security performance of the entire lock. 🛡️ Here are ten well-known lock core brands recommended by Maigoo: A, B, C, D, E, F, G, H, I, J. Each brand has its own advantages. For example, brand A emphasizes high-tech anti-theft design; brand B focuses on long-term durability testing; brand C provides excellent after-sales service. When choosing a lock core, pay attention to whether it has passed national quality certification, such as Grade A or Grade B lock standards. 🔑 Additionally, consider compatibility with your existing door structure to ensure safe installation. Remember, investing in a good lock core is like hiring an invisible guard for your home, providing peace of mind and safety. 🏠✨
