How to use Xinduo anti-theft door lock

1. In the house, press the movable handle to push out (open the outer door) or pull in (open the inner door). After opening the door, do not force the angle of the door to exceed the normal opening angle (the normal opening angle is 90 degrees-100 degrees). The user enters the house after the door is opened. Before closing the door, please check whether the locking tongue has been retracted into the door body. If not, please press the movable handle in the house and close the door after the lock tongue is fully retracted. Users can close the door in the same way after going out.

2. Don't forcibly close the door when the lock tongue is exposed! Otherwise, the door lock will be damaged. (You also need to close the small door inside the door) If you need to use door safety at night (after safety, people with keys outside the house can't open the door, and people inside the house can't open the door by pressing the handle), please turn the "I" knob under the movable handle inside the house by 45 degrees. When safely released, turn the I-shaped knob to the horizontal position.

3. If the user needs to use the insurance after going out (it can increase the anti-theft time), please close the door in place, insert the key into the lock cylinder and turn it counterclockwise (outside the door) or clockwise (inside the door) for 360 degrees, then pull out the key (it can only be used when there is no one in the house).

If the house is being renovated, please use key A and key B before unpacking. After the renovation, the owner inserts the key B into the outdoor lock cylinder, rotates it 360 degrees counterclockwise (opening the door from the outside) or clockwise (opening the door from the inside), and then turns it back to its original position and pulls it out.

5. Anti-theft door lock Then insert the B key into the lock core to open the door lock. At this point, the B key has been completely used, and the A key can no longer be used. Users should not discard the A key casually, but should discard it after the A key is damaged to avoid unnecessary losses.

How much is the anti-theft door lock?

1, Class A anti-theft door lock. We know that you must have a key after you have a lock cylinder, but you chose this A-class lock cylinder. The shape of the key is flat or crescent. Class A lock cores are common on other days, and the anti-theft coefficient of Class A lock cores is poor, which is not conducive to anti-theft. The price will also be cheaper, about 100.

2. Class B anti-theft door lock. Next, let's talk about the B-class lock core. Its anti-theft coefficient will be higher and its reliability will be better than that of the A-class lock core. If it is to be destroyed, it may take 15 minutes, and the time to prevent it from being pried open is also 15 minutes. The price will be a little more expensive, that is, around 200 or 300.

3, super class B anti-theft door lock. The so-called super class B is more reliable than class B, but it is similar to class B in other aspects, except that the anti-theft time has been improved to a certain extent. Its technical opening time is 260 minutes, which is very cost-effective. For example, more than 600 RMB, almost 200 RMB.

The above is about the use and cost of the new anti-theft door lock, hoping to bring help to friends in need.
