Is it feasible to have a security door key? How much is the security door key?

When the developers were designing the building, most of them would design two doors as the safety of each household. There was a security door outside and a decorative door inside. It’s different now. Just one security door can solve all the problems. It looks beautiful from the inside and is safe from the outside. The only thing that can’t be changed is that we may lose the key during use, and there is no lock for the door lock. What is necessary, we only need to have a key to it, just happens, the decoration home network today is about the knowledge of the security door key .

First, is it possible to match the security door key?

1, the security door keys are basically all available, as long as the imported security door can be equipped, as long as the domestic key blanks are available. We only have to find key-key shops or mobile stalls at some markets. It can help us to do a good job of the security door key, and it is easy to take with it.

2, but there is a small part that can not be matched, you can change the lock core. It should be noted that the key of the cross-shaped lock cylinder can be matched, and the keys of the S-shaped and M-shaped lock cylinders cannot be matched, but the lock core can be replaced. Because there are some different types of different brands, the lock core of the security door is also different from the different keys. It is recommended to ask this question when purchasing the brand's security door, and plan ahead. Security doors have different security features due to different price points. Therefore, it is recommended to buy products with higher anti-theft performance. In addition, we have to talk about it, the key should be placed in the attention, can not be lost.

Second, how much is the security door key?

This depends on how complicated the keys are, because some of the security door keys are quite strange, it is difficult to find a similar model to match. So everyone will be a better choice when they choose. Yes = some of the more complicated ones may cost about 30 yuan, because after all, it is a security door, so the configuration will be more elaborate. Of course, there are ordinary ones, probably about 8 yuan. So everyone will be a better choice when they choose.

Third, the difference between the security door decoration key and the official key

1. For the sake of easy distinction between the manufacturers, the 6 B keys are packaged in a transparent hard case, and the 2 A keys are hung outside. Some A and B keys have different colors. The 2 A keys are yellow, and the 6 B keys are white and packaged in a box. (In addition, some keys are locked with a c key) There is an instruction manual on the back. The industry mainly reads clearly before use, recognize the use of the two keys, do not confuse, avoid the improper use of the two keys.

2. If A and B keys are carefully observed, experienced people will find that one of the seven pits above the key is different (the average person does not pay much attention to it, thinks that there are two keys, nothing the difference). The deepest pit at a certain position on the A key, the shallowest (even flat, no pit) corresponding to this position on the B key, generally the position of the 7th or 1st marble. Speaking of the people I want to be here, I must have thoughts in my heart, so I will remind the homeowner that A key must be taken back after use and properly preserved or destroyed.

Fourth, how to open the key inside the security door

1. You can try to use the key to force the top twice. If the key inside the security door is horizontal, then the key is easy to get out, then the problem can be solved.

2, if this method does not work, then find a professional unlock to help, see if they can take the key of the security door and open the security door.

3, if the key to the security door is not easy to get out, and did not ask the professional master to help, then you can force the handle to the reverse direction, or with the help of tools such as pliers, the handle is easy to fall.

Although the quality of the imported security door may be better, but it is best to consider it when installing, because the imported security door key can not be matched, then you can only spend a few thousand dollars to change the lock. With a key, it only costs about 10 yuan. It can be seen that the gap in the middle is still quite big.
