Nowadays, more and more people choose to install fingerprint locks, thinking that this can improve the security of their homes. After all, a fingerprint is a unique identifier for each person and is not as easy to get lost or duplicated as a key. But are fingerprint locks really more secure than key locks?
We might as well listen to the analysis of the locksmith and see how they deal with various door locks, and maybe you will find that you have chosen the wrong one.
1. The principle and classification of fingerprint locks and key locks
First of all, we want to understand the principle and classification of fingerprint locks and key locks. A fingerprint lock is a smart lock that opens the door by identifying fingerprints. Fingerprint locks can also usually be opened by passwords, cards, emergency keys, etc.
A key lock is a mechanical lock that opens the door through the combination of the key and the lock cylinder. Key locks can usually only be opened by a key.
According to the national standard "Mechanical Anti-theft Locks for Anti-theft Security Doors", mechanical anti-theft locks are divided into three grades: Class A, Class B and Super Class B (Class C), of which Class A is the lowest and Class C is the highest. According to the national standard "Smart Door Lock", smart door locks are divided into three levels: first, second and third, of which the first level is the lowest and the third level is the highest.
Second, how does the locksmith open various door locks
A locksmith is a person who specializes in opening various door locks, and they usually have professional tools and skills that can open most door locks in a short period of time. However, not all door locks can be opened easily, and some need to be broken or replaced before they can be opened. Let's take a look at how lockpicks deal with various door locks.
Fingerprint lock
The advantage of a fingerprint lock is that it can only be unlocked by a pre-entered fingerprint, eliminating the need to carry a key or remember the password, reducing the risk of loss or leakage. However, it is also possible for fingerprint locks to be cracked, for example by spoofing the fingerprint identification system through fake fingerprints or advanced devices.
If the fingerprint recognition system is cracked, then the locksmith can use a fake fingerprint or device to simulate a real fingerprint to open the door. If the fingerprint identification system is not compromised, then the locksmith will have to try other ways to open the door, such as a password, card or emergency key.
Passwords and cards can be forgotten or lost, so they are less reliable. Emergency keys are the last straw, but they can also be hidden away or forgotten at home. If there is no other way to open the fingerprint lock, then the locksmith can only destroy the lock or change the lock, which will cause loss and trouble.
Key locks
The disadvantage of a key lock is that it requires a key to be unlocked, which can cause the lock to be picked open or opened if the key is stolen or duplicated. However, the security of the key lock also depends on the level of the cylinder, which has different anti-theft capabilities and difficulty of opening.
Class A cylinders are the lowest level of lock cylinders, and its key structure is simple and easy to copy or prie. The locksmith can use some simple tools, such as crowbars, wires, master keys, etc., to quickly open the A-grade lock cylinder. Class B cylinders are medium-grade cylinders that have a complex key structure that is not easy to copy or prie.
The locksmith needs to use some professional tools, such as decoders, code pullers, decode keys, etc., to spend a certain amount of time to open the B-level lock cylinder. The C-grade cylinder is the highest level of lock cylinder, and its key structure is so complex that it is almost impossible to duplicate or pry open.
The locksmith needs to use some advanced tools, such as electronic decoders, electronic code pullers, electronic decoding keys, etc., to spend a long time to open the C-level lock cylinder.
If you encounter a high anti-theft door lock above grade C, it is difficult for the locksmith to open it through technical means. At this time, they need to consider whether to break the door lock or change the lock. However, doing so will bring more losses and troubles to consumers.
3. Which is more secure, fingerprint lock or key lock
Through the above analysis, we can see that fingerprint locks and key locks have their own advantages and disadvantages, and there is no absolute security. Although fingerprint locks are convenient and fast, they can also be cracked or invalidated; Keylocks, while traditionally stable, can also be lost or duplicated. Therefore, there is no definitive answer to which is more secure, fingerprint lock or key lock.
When we choose a door lock, we should decide according to our needs and preferences. If you pursue convenience and intelligence, you can choose fingerprint locks; If you pay attention to stability and economy, you can choose a key lock. No matter which door lock you choose, you should pay attention to care and maintenance to avoid malfunction or damage.
At the same time, we should also pay attention to improving our security awareness and prevention capabilities, do not trust strangers or unscrupulous merchants, do not disclose their fingerprints, passwords or card information at will, and do not put emergency keys in places that are easy to be found.
If you are unfortunate enough to encounter a situation such as being locked or losing your key, you should contact a reliable locksmith in time, and negotiate with them on the price and method, and solve the problem as soon as possible on the premise of ensuring your own safety.
