If they want to let the unlocking company open the lock, they feel that the lock cylinder is wasted. In fact, as long as you master the unlocking skills of some door locks, you can open the door even without a key, and you don't have to worry about having a key again.How to open the door without a key? What is the unlocking technique of the door lock?How to open the door without a key? First. Fill the key slot Unlocking process: Lee took out a set of unlocking tools, including a small box containing several tin foils. "This method has been in existence for a long time, and it is common for unlocking masters to use it. Of course, thieves also understand this technique." Lee took out a lock, then put the tin foil in a special tool, and inserted B through another tool. Level lock cylinder. Then fix the lock cylinder on a small vise to simulate the unlocking process. I saw that the lock was smoothly opened by shaking it from side to side for about 1%. The reporter found that there was a groove on these tin foil strips with seven or eight small cracks. According to Lee, these grooves have been polished before. "Because the tin foil has a certain degree of hardness with the help of a key-like tool, it can be inserted into the keyhole." Lee said, "This unlocking method uses tin foil to 'fill out' the key slot, which is equivalent to making a one-time key on site. Therefore, the unlocking process is effortless, just like using the original key. This method can be opened even when the A and B lock cylinders are locked and not locked." Second, hit the lock cylinder Unlocking time: about 30 seconds Unlocking process: Lee first inserts one end of a key into the Class B lock cylinder, and then hits the other end of the key with a hammer. During the tapping process, he will try to twist the key. The reporter found that the lock cylinder was opened after only 6 hits with a hammer, which took about 30 seconds. Lee told reporters that this method of unlocking mainly uses the design loopholes of the A and B lock cylinders to hit the lock cylinder marbles to unlock the lock. For anti-theft doors with A and B lock cores that are not locked, a thief can open it in just a few seconds. If it is locked, the time for committing the crime will be extended several times or even longer. In addition, this unlocking method will not damage the structure of the lock, and citizens can open the door smoothly with the key after returning home. Third, insert and unlock the bolt Unlocking time: 6 seconds Unlocking process: What the experiment needs is a made rectangular plastic card. Li Qiang first inserted the card into the gap between the door and the door frame, then slid down to the position of the lock tongue, and then smoothly opened the door-the whole process took 6 seconds. "This method is a relatively primitive unlocking method, but it is more common. The incidents are more common in old-fashioned residential areas. The thieves mainly target wooden doors and old-fashioned anti-theft doors." Lee said that this unlocking method is suitable for the unlocked state. The lock core or the safety plug cannot be successful. What is the unlocking technique of the door lock? Chewing gum unlocking: The thief stuffs the chewing gum into the keyhole, and uses a tool to push the softened gum into the keyhole. Because some old-fashioned lock cylinder marbles are of average quality or short in length, after being "squeezed" by chewing gum, the thief inserts the lock cylinder into the lock as a tool to open the lock. Crochet needle unlocking: Insert a special crochet needle into the lock hole to simulate the key unlocking principle, and unlock the lock by adjusting the position of the lock cylinder pin. Cat's eye unlocking: Pry open the "cat's eye" on the anti-theft door, use a "three-section stick" and other tools to penetrate the "cat's eye" into the room, and press the built-in door handle or lock of the anti-theft door to open the door. Experimental conclusion: the more complex the key structure, the more difficult it is to open the lock. After that, Lee also used the super-B-class lock to fill in the key slot and hit the lock cylinder, and found that it could not be opened even with the best effort. The reporter saw that the shape of the Super B-class lock is more complicated. In addition to the marble structure, there are special grooves that make it difficult to pry open. How to open the door without a key? The several unlocking techniques recommended above are very useful. If you forget to bring the key, you can try the several unlocking techniques recommended above. What are the unlocking techniques for door locks? Although these unlocking techniques are very effective, it also shows that this kind of door lock is insecure.

Just read an article about biometric door lock, below I attached with the content and comparison with FUYU lock:After moving to a new house, I was locked out of the door twice in half a year. I had to wait for my wife to come home to save me. So the idea of buying a fingerprint lock came up. I read 40 or 50 articles about various locks before and after, plus the latest purchase. Experience summary part of one-sided feelings.First compare traditional locks and smart locks. In contrast, smart locks have only two advantages: they look very advanced and they are very convenient to use. The disadvantages are more:1.The smart lock with more unlocking methods theoretically has a greater chance of being stolen, just like the keyless entry of a car. Copy fingerprints, small black boxes, mechanical keys, etc.; while traditional locks can only use mechanical keys, and the highest-level mechanical keys on the market require professional machines, which are generally not matched by the masters with locks.FUYU biometric door lock: Maybe he needs to read more articles or go to the fair to see more smart locks. With the rapid development of technology, the smart lock are getting more and more security. Such as our FUYU keyless door lock, because we adopt FPC fingerprint sensor, which makes the fingerprint not able to be copied, as well as the small black boxes, which is actually means Tesla coil interference unlock, fuyu digital door lock also have inspection regarding this issue and have got quality test report by authoritative organizations.2.Smart locks consume power. Powerful and poor-quality locks consume fast power. You need to change a set of batteries at the earliest in about 20 days. The mechanical lock is set once and for all.FUYU digital lock: most of the digital lock needs a lot of power consumption is because of they need lithium battery, and the lithium battery is also not safe under certain conditions, so FUYU digital lock only use Alkaline battery, which is cost-effective and longer life(normally can be used for 1 year depending on the frequency of usage)  3.Smart locks are afraid of failures. Smart locks are counted as electronic products, but there are no electronic products that do not make mistakes. When the smart lock crashes, it may not be opened and can only be demolished, or it may not be locked and can only be replaced. The smart lock embedded module has one more electronic module than the traditional lock, so the stability of this part must be considered when purchasing. Even if the traditional lock fails, people with a little hands-on ability can repair it by themselves because of the simple structure.FUYU digital lock: the complete lock is made in house, including the trim die-cast, lock case, cylinder, and even the circuit board. All the accessories are under strict quality inspection to ensure the stable performance.By instance, if the lock have problem, and even without battery, only use a key could open the door.4.The overall weight of the smart lock. People who say that the heavier the better, I can only laugh without saying a word. This is why the domestic cars have been lengthened and the speakers have added a lot of unnecessary iron. My home has a single-hole lock body, and the smart lock manufacturer I bought this time has stopped producing the single-bolt lock body, because the single-bolt cannot support the weight of the smart lock, and there are often problems.FUYU keyless door entry lock: We do agree with this opinion, and it’s not right to judge a smart lock by weight.After all, it’s good to keep an eye on each aspect of the smart deadbolt lock, such as the life cycles, securities etc. And we hope you all find your idea smart lock.
