AB lock is illustrated with the technique opening method, with unlocked video teaching. AB lock is a common anti-theft door lock key configuration, A lock key and B lock key separate, A lock is usually used for decoration, the workers open the door through the A lock key decoration, after the renovation work, A lock key can continue to use if the owner The security anti-theft requirements are more stringent, you can use the B lock key to open the security door, then A lock will lose its function, especially for new house decoration, this lock has obvious advantages in convenience.
A, B key lock, it has two kinds of AB keys. It is a type of lock that consists of marbles and other structures. The depth of the pit is different. It is the same as the principle of the different teeth of the flat key.
The advantage of the AB key lock is that it can meet the needs of people to decorate their homes, avoiding the loss of the key to open the door when the renovations are in turmoil, or copying the door opening keys for those who have bad intentions, and may avoid the owner's Unsafe factors can also avoid the troubles and costs of replacing locks for safety after renovations, so they are welcomed by people.

1. The lock cylinder is designed to be unlocked inside the door, so the middle part of the inner and outer lock cylinders is equipped with a clutch device. When the side lock cylinder is inserted into the key, the front end of the key will be the top of the side of the plug device. In the engagement groove in the middle cam, the plug device in the other side slot can be pushed out of the slot at the same time. When the screw cylinder is twisted, the plug device drives the cam toggle lock to unlock.
2, A, B key insertion depth of the lock cylinder in two ways, one is to use the key to the root positioning; the other is to use the key to the front position. The function of the positioning is that when the key is inserted, both the lower beads can be dropped into suitable pits, and the front end of the key can be used to engage the plug device with the cam to drive the cam to rotate.
AB Lock Technology Opened Method IllustrationThe method used to open the AB Kabbah lock usually requires the use of a key and the impact. After making the key, place it in a plastic bag. Inside the plastic bag, put some pencil powder (it seems to be the same as playing billiards. The club head is coated with wax, which is particularly slippery when hit. It takes two to three times more than the key blank that has not missed the pencil powder.) When hitting, it must be given a straight line to focus on it. The device that normally locks the door is one meter above the ground.
When hitting, it is necessary to squat down. When the right hand strikes something, such as: using a rubber handle to handle it, you can't put the handle to the sky. Assuming that the handle is turned upside down, the arc that occurs when you hit the key is the strength. Down, this is not open to attack.
The screwdriver can't be higher than the keyhole, and the screwdriver is heading backwards. The curvature of this happening, and then hitting the key head, the force is straight, and the child easily breaks open. After the key is inserted first, two more compartments are pulled out, and then the collision is performed. The method is the same as described above). The key blanks are best made of iron key blanks, because the ferrous burrs on the head of the iron key blank can be used for a long time. Normal copper key blanks can also be used, but the application time is not long. The keys have been used for a long time. The rake can be used for succession, and the pit can drill deep and deep, but not drilled. Usually 7 marbles drill 8 on the line, 9 most, more than one drill is mainly to give it a collision stroke, do not rush to do a good job, first plug into the practice lock look (put more on the practice lock A number of high marbles) When reciprocating and pulling on the training lock, we can see if there are any bullets that will exceed the lock separation line. Assuming that there is more than one hole, we need to drill a bit deeper. Of course, the keystroke is not difficult to say, but It is still worth noting that there is a way forward.
How to make the keystroke in front of you has now been said, the keystroke is inserted in and the one or two pits are pulled out. (One or two teeth) The hand holding the key first twists a little quietly in the opening direction. Do not be too heavy. Take it. Whatever it is to hit, it's really just a handy plastic screwdriver. No need to use a hoe or something too heavy. Don't think that knocking is heavy and the bump rate is high. When the driver knocks it down, take the key immediately. The hand of the blank is slightly twisted on the basis of the quiet force. The timing is better. Suppose we haven't twisted and pulled it out to try again. The best intensity is very light and we need to have a skewed way.
AB locks the production of keystrokes and impact methods: AB lock has many varieties and brands, some brands are not the same pitch width and thickness, but also to do more than a few types, there are positive and negative slots, there are Semicircle AB lock. Find more than a few of them, half-circle insert heart lock, than the original key 7 beads or 8 beads .. with a machine tool to play well before the 7 or 8 positioning .. and then in the key point of the embryo directly hit the transparent point (The transmission point diameter is 1 mm). So it is able to use. Economical. So say, to do more than a few types. Because the success of the crash key hits the eye, the depth of the eye is revealed. From the perspective, the link is the title of the lock. All must be in the eyes of things, assuming that some marbles in the top of the eyes and the top of the gap between the two eyes that can not be knocked off, followed by the cooperation of both hands Jin Li.
Seven beads AB lock, can make eight beads of the key is also said to be labeled as eight eyes. Eight beads of AB lock, hit nine eyes, let it one or two more hit. Eyes hit the deepest, almost wearing the bottom, in the processing, is in front of one more eye. The first is to do the original old key, do a good model, and then use the key machine to copy more than a few to spare. Do not give it too small when drilling, to avoid bumps when hitting resistance. Also don't be peaceful, flat without hitting slope,
Each kind of brand's lock has different pitch, width, and groove shape, so it is necessary to do several types and use them together. Ties, teeth to match, accuracy in place. The top of the bumper asks for a tooth profile, the second is the depth, and the slope is better. Use a rubber hammer as much as possible, and beat it better than using other hammers. Because of its long-term effect. Do not easily damage the key, feel is understood, everyone is similar.
Pinball locks are usually used, for example, bulls, permanents and other single-row marble locks, which can be unlocked with the original key. Each lock must be equipped with a bullet. When equipped, it can be equipped by hand, find an original old key, and use the above tooth profile to make it into the deepest tooth shape. It is assumed that the five-toothed shape can be twisted into a six-tooth shape, and one tooth can be added behind. When the blank key blank is used, don't make the tooth shape too steep, avoid large time-to-weight resistance when hitting, and it shouldn't be too flat, and it shouldn't hit the slope of hitting.
When hitting, it is necessary to insert the key first, and then pull out a square. The handle can be hit with a rubberized handle. Strike force must be a straight line to it, the left hand must use the key must be virtual, quietly move in the open direction. A few more exercises can guarantee a higher success rate.
