Why can t I take out the lock cylinder of the anti theft door?

If you can't pull the lock cylinder out of the lock body no matter how hard you try it, you have to consider that it may be because the inside is stuck or the inside is too astringent , it will lead to the inability to pull out. You can add oil directly to the lock body to increase the lubricity, and you can effectively pull out the lock cylinder.

If it is because the lock plate in the lock cylinder is stuck, you need to use a small iron wire to return the paddle inside first, and then pull out the lock cylinder, which will also become simpler.

Analysis of common failures of locks.

1. The lock cylinder is the soul of the entire lock, and the lock cylinder is also the most prone to failure, such as the situation that it cannot be rotated. Mainly because of the wind and rain for a long time, or the invasion of dust, it will lead to corrosion inside, there is a lot of ash will cause the lock cylinder can not be rotated, in this case you can drip diesel or engine oil into it, wait a little, wait until it is moisturized, and then insert the key into it to try.

2. Sometimes the key insertion and unplugging is inflexible, we can pour solid wood into the lock cylinder to clean the ash, and then switch it several times, in this case, it is best not to pour oil into it, which will affect the activity of the bullet, but will lead to the inability to unlock.

There is also a screw on this side of the deadbolt.

Unqualified security doors, as the name suggests, do not meet the national standard of security doors. There are many kinds of unqualified security doors in the market, as long as consumers maintain a calm mind. Don't be tempted by low-priced doors. Basically, you won't buy an unqualified security door.

Fence type security door is usually more common steel pipe welded security door, its biggest advantage is ventilation, lightweight, beautiful shape, and the price is relatively low. The upper half of the anti-theft door is a fence-type steel pipe or steel plate, and the lower half is a cold-rolled steel plate, which is locked with multiple locking points to ensure the anti-prying ability of the anti-theft door. However, in terms of anti-theft effect, it is not as good as a closed anti-theft door.

Plate and material:

1) The plate material can be steel, stainless steel, steel wood, copper or other composite materials.

2) Thickness of steel plate.

a) The door frame should be selected according to the level of B, C and D of anti-theft security.

b) The thickness of the outer panel and inner panel of the door leaf is expressed in the form of "outer plate and inner plate", and the level of B, C and D of anti-theft security should be selected respectively.

c) The thickness of the plate of the Class A anti-theft security door shall be selected according to the product design under the condition that it conforms to its anti-vandal performance. If the steel plate is selected, its thickness should not be lower than the thickness and allowable deviation requirements of the door frame and door leaf of Class B anti-theft security level.

If you can't take it out depending on the situation, it should be that the paddle position in the lock cylinder is not in place, and you need to use the key on the inside to return to the normal position. As shown in the figure below: the black place in the middle is the lock cylinder paddle, normally as shown in the figure below, there are some lock cylinders, such as the position of the lock cylinder paddle of the individual door belt of Qunsheng or Buyang is biased, and a small piece is slightly pushed out, so that the lock cylinder can not be taken out directly.

Be sure to pay attention. You need to use the original key to screw a little to do, if you don't have the original key, then you can only destroy. Either the cylinder is broken in its entirety, or the lock body is twisted.

If the lock is welded, use a grinder to grind the solder joints off, and then replace it, and fix the lock with self-drilling screws when installing a new lock.

If you can't get it yourself, I suggest you go to a professional for help.

They have the tools and skills to help you get it out.
