Which one is more cost effective, with a key or a lock cylinder?

This problem depends on the situation, because in most cases there is no way to make a choice between matching the key and changing the lock cylinder, for example, we can choose to match the key if we have the key, in this case we can choose to change the lock cylinder, we can also choose to match the key, but the key is easy to make, the lock is no problem, so why should we change the lock cylinder? So you only need to have an extra key for someone else or a spare.

If we have been locked out of the door, the lock can not be opened, at this time we can only dial the lock company to help us unlock, and their way to unlock is often not to give you a key, but directly to break your lock cylinder, let you change a new lock cylinder, in this case, you have no way to make a choice between the two, you can only obediently replace the lock cylinder, and then there is a new set of keys for you, it can be seen that there are so many choices, You just need to make the right choice according to the right situation.

Personally, I think that with the key this is still lower than the cost of changing the lock cylinder, the cost performance is naturally higher, now the locks are more durable, with a five, seven or eight years is basically no problem, if you really need to match a few more keys to put there for standby, my approach is to give the key to the home to the parents a hand, to the child, I and my wife a hand, so as to prevent one of them from losing the key, after losing it with another one, as long as the lock is not bad our key casually matched, Therefore, it is more cost-effective to match the key than to change the lock cylinder.

It is worth a lot of money to change a lock cylinder, generally a normal lock cylinder costs more than 100 yuan, and a better lock cylinder needs more than 200 yuan, which may be worth using.

It's higher, but this is undoubtedly a bit higher than the cost of the key, like the lock cylinder itself is a durable product, a similar lock cylinder can be used for five or seven eight years, no need to change it.

About the same value for money.

If the key is lost, you can change the lock, you can also change the lock cylinder, in general, it is recommended to change the lock directly, only in this way can we protect our home more safely.

1. For the sake of safety, it is recommended to change the lock. Generally speaking, in the case of losing the key, even if someone picks up the key, they may not know to open the door, some people are lucky not to change the lock, thinking that the key is only a few yuan, and the cheapest to change the lock is also dozens of yuan, the quality is guaranteed to be super B-level and even hundreds of yuan, it seems not cost-effective, it is a bit of a fuss.

2. Don't be afraid of 10,000, just in case. With the key, the money is saved, but for this there is a hidden safety hazard; Changing the lock in time seems to be a bit of a waste at first glance, but the safety factor is high. In particular, after renting a rental house, buying a second-hand house, or renovating a house, due to the large number of people coming and going, the person who owns the key is more uncertain, and the security risk is even greater.

If you have any questions and do not understand, you can consult Guangdong lock king. The company has a team of senior locksmith engineers, more than 60 Mazda unlocking service vehicles, more than 160 professional and technical personnel, and direct outlets throughout the province's major cities, such as Guangzhou, Foshan, Zhongshan, Jiangmen, Zhuhai and other places. It can be replaced with various civil locks, such as anti-theft door locks, import locks, advanced electronic locks, home safes, etc.

It is more cost-effective to have a key. Because the cost of the key is lower, it can also accomplish the desired purpose. In comparison, the cost of changing the lock cylinder will be high.

If the key is lost, it must be cost-effective to change the lock cylinder, and it is not safe to simply match the key.

It must be equipped with a key, a key is only a few dollars, and it is much more expensive to change a lock cylinder.

It mainly depends on the model of the lock cylinder, if the model of the lock cylinder is more common, change the lock cylinder, because the lock cylinder is cheaper.

Yes. If you use a normal lock at home, it is better to match, as long as you remove the lock or call a professional to remove it.

Generally speaking, there will be two ways to match, one is to take n keys to try to open, if the opportunity is good, it is easy to match, the second is to dismantle the lock cylinder and finger down according to the lock cylinder shrapnel, this method will not be difficult, it is more time-consuming, it is recommended to use the first method, if you can't open it, change to a new one.

Precautions for using keys

1. When in use, if it is a new lock cylinder, there will often be a phenomenon that the key is not very smooth, at this time, most people will feel that the quality of the lock cylinder may be problematic, in fact, this is a relatively normal phenomenon.

If you find this situation, you can add some graphite powder to the keyhole to make it lubricate, and you can't add any oil to it, if you add grease, it may stick to the spring of the pin, which will cause the lock to not rotate.

2. When closing the door, you should hold the handle, and then screw the lock tongue into the lock body, and you can release your hand after the door is closed, and you can not hit the door hard, or the service life of the lock will not be reduced.

3. When you find that the deadbolt is sticking out of the door, you can't hit it violently to avoid damage to the door frame.

There is no key to rely on the lock with the key to exist in theory, hehe, you need to remove the marbles for comparison, if it is an anti-theft door lock, it is even worse, because the vast majority of the lock cylinder removal is destructive and cannot be restored, unless it is a professional production lock cylinder company. So you should have to change the lock.

1. The key can be equipped through the lock cylinder. According to the size of each marble in the lock cylinder, the original key can be matched, and the marbles need to be removed for comparison, if it is an anti-theft door lock, it is even worse, because most of the lock cylinder removal is destructive and cannot be restored, and you should find a professional lock cylinder company.

2. Lock cylinder classification:

1) Class A lock cylinder, the time to prevent technical unlocking is not less than 1 minute, and the time to prevent destructive opening is not less than 15 minutes. The A-grade lock cylinder is an old-fashioned lock cylinder, the key is a cross plate type or a crescent type with a convex key slot key, and there is a row of concave key slots on one or both sides, this kind of key thief can be opened in a few seconds with tin foil, if you still use this kind of key at home, change it quickly. Class A cylinders are no longer able to protect against thieves.

2) Class B lock cylinder, the unlocking time of the prevention technology is not less than 5 minutes, and the opening time of the anti-impact is not less than 30 minutes. The B-level cylinder key is flat or crescent-type, and the B-level lock key is more complex than the A-class key, and the key slot is single-sided or double-sided, with two rows of concave or cylindrical multi-point concave key holes.

3) Super B-level lock cylinder, the technical opening time is more than 270 minutes. The super B-level lock cylinder key is a flat type, and the key slot is a single-sided or double-sided two-row concave plus S-shaped, or an inner and outer double snake type internal milling groove structure. It is the most complex cylinder and the most secure cylinder, and the tool cannot even be opened for more than 270 minutes.

It can be matched, and the general lock is about 30-50 yuan.

Yes.

The national standard for anti-theft locks is divided into "ordinary protection level" and "advanced protection level", the former is represented by the letter "A", and the latter is represented by the letter "B". The so-called super B-level and C-level locks on the market are defined by some merchants themselves, and strictly speaking, they should be counted as B-level locks.

However, due to the fact that the C-level lock cylinder is more troublesome with the key, the requirements for the key machine are very high, so there are few places that can be matched. Generally, only all very large lock stores in a city can be matched, and due to the problem of accuracy, it may not be guaranteed to be used. Rework is required.

Nowadays, every household is equipped with an anti-theft door, which can add a guarantee to our home life and can also play a good fire prevention effect. There are many levels of anti-theft door lock cylinders, and the security of C-level lock cylinders is higher, and there are more owners who choose C-level lock cylinders. What happens if I lose my Class C cylinder key?

Can I match a Class C cylinder key? How to buy a C-class lock cylinder? Let's take these questions and find out together!

Can I match a Class C cylinder key?

Yes. Because the structure of the C-level lock cylinder is more complex, the technical unlocking time is more than 300 seconds, and the texture of the key is more complicated, so the key of the C-level lock cylinder is more troublesome to match, and there are higher requirements for the machine, so it is recommended that you go to a professional large-scale lock shop with the key to ensure the accuracy of the key and avoid subsequent rework.

How to choose the right lock cylinder.

1. Look at the lock cylinder structure.

Relatively speaking, the safety performance of the blade side column type is higher than that of the marble, and in layman's terms, the more complex the lock cylinder pattern, the higher its safety.

2. Look at the weight of the lock cylinder.

Generally speaking, high-quality lock cylinders are generally heavier, while inferior lock cylinders are generally lighter, this is because high-quality lock cylinders are mostly made of high-quality raw materials, and the number of beads inside the lock cylinder is larger, and the anti-theft performance is also better.

3. Look at the color of the lock cylinder.

If the color of the lock cylinder is dark yellow, it is mostly a copper core, which is hard and firm, with a high anti-theft coefficient, and most of them are treated by electroplating process, which makes the surface of the lock cylinder look smoother and brighter. If the color of the lock cylinder is off-white, and there are some bubbles on the surface, most of the materials used are zinc alloy, which has low anti-theft performance and dark color.

4. Look at the smoothness of opening.

When purchasing, we can insert the key into the lock cylinder, try to rotate in the positive direction or the opposite direction, feel whether the key is in use, whether it is smooth, whether there is a stuck phenomenon, if the key is stuck, it indicates that the anti-theft coefficient of the lock cylinder is low.

The key of the C-class cylinder can be matched.

The lock cylinder adopts a number of anti-theft technologies, a variety of special-shaped anti-pull bullets, to prevent technical opening, with a unique design of the bullet and blade structure, with a high safety performance of anti-technical opening. The lock tank is equipped with a precision number bullet and a special-shaped bullet structure, which will be automatically locked when the number bullet and the special-shaped bullet must be pulled at the same time when the technology is opened, so that the technology will be turned on in vain. The lock cylinder adopts a variety of special-shaped marbles and multiple combinations, which can compile up to billions of key numbers, so as to achieve zero mutual opening of the area (1 in 16 million).

The lock cylinder is equipped with a lateral internal pressure side post bayonet device, which greatly improves the ability to prevent violent torsion.

But it is just the opposite of the right, that is to say, the anti-theft function of the C-level lock cylinder is the best, at present, we have no clear standard for the positioning of the C-level, generally speaking, we will call some of the anti-theft functions better than the B-level as the C-level, of course, it can also be said to be super B-level.

If you want to search for the brand of C-level lock cylinder on the Internet, it is difficult to find it, because there is no clear definition of C-level lock cylinder, if you really want to search, you can search for super B-level lock cylinder, this kind of lock cylinder is the current C-level lock cylinder.

C-grade is good, but it is recommended to go to a more regular and larger place to change, there are too many imitations of this kind.
