Anti-theft door locks play a crucial role in ensuring the safety of your home. Beyond being strong and durable, stability is also an essential factor. A malfunctioning lock that doesn’t open when it should or doesn’t close properly can significantly disrupt daily life. Therefore, when purchasing anti-theft doors, the quality of the door lock is of utmost importance. In this article, I’ll guide you through the quality standards of anti-theft door locks and provide insights into their price and selection.
1. Installation of Anti-theft Door Locks
The lock face of an anti-theft door lock typically uses an advanced integrated cast steel structure, without any artificial rivets or plastic parts inside. This special manufacturing process ensures the robustness and high resistance to damage, making these locks suitable for both residential and public buildings.
Normally, it's best to install the anti-theft door lock after the door has been painted and fully dried. This prevents paint from sticking to the lock, which could affect its appearance and functionality. It also helps reduce the risk of paint corrosion on the door and extends the lifespan of the lock.
1. Drill the lock body installation holes on the anti-theft door according to the dimensions provided by the lock manufacturer.
2. Insert the lock body into the pre-drilled holes, secure it with screws, and then install the outer panel components. Align the square hole on the handle with the square rod hole on the lock body and fix it in place.
3. Install the inner panel components, align them carefully, and tighten the screws. Insert the lock core from the inside out, secure it with a screw, and install the lock box or plate on the door frame.
4. After the initial installation, test the lock by turning the outer and inner handles to ensure the latch moves smoothly. Turn the rear panel knob to check if the square tongue retracts and extends easily. Use the key to rotate back and forth and confirm smooth operation.
5. Once all screws are tightened, repeat the testing process several times. If the movement feels stiff, loosen the screws slightly and adjust the position until everything operates smoothly and conveniently.
2. Price of Anti-theft Door Locks
1. Grade A Anti-theft Door Locks
Among the different security grades, Grade A is the lowest level and offers minimal protection. While it may be acceptable for interior doors, it’s not recommended for exterior doors due to its weak anti-theft performance. The price is relatively low, usually around 100 yuan, depending on the brand.
2. Grade B Anti-theft Door Locks
Grade B locks offer better security than Grade A, but they can only resist forced entry for about 15 minutes. After that, the door might be compromised. These locks are more affordable than higher-grade models, typically costing between 200 to 300 yuan, though prices may vary.
3. Super B-Level Anti-theft Door Locks
Super B-level locks are an upgraded version of standard B-level locks and provide greater reliability. These locks are often produced by well-known brands and can resist forced entry for up to 260 minutes. As a result, their price is significantly higher, typically ranging from 600 yuan to over 800 yuan.
4. Super B-Level Blade Locks
The highest level of security is offered by Super B-level blade locks. These locks use advanced technology and have highly secure cores that are difficult for thieves to manipulate. They can withstand forced entry for up to 270 minutes, making them extremely safe. However, their price is quite high, ranging from 300 to over 800 yuan.
Here is a sample of some popular models and their prices:
