What should I do if the security door can t be opened? Urgent!!

Is your home in **? Has it been raining a lot lately? If the weather is humid and there may be a little rust inside, get some pencil end to try, or oil.

You can use a little force without breaking the key. If it still can't be opened, it may be that there is a problem with the lock, and the last resort is to find a lock. Let me give you an analysis of the reasons why the security door cannot be opened.

1 Poor quality of the lock cylinder The key does not turn 2 The quality of the lock body is poor The key does not turn back 3 The door leaf and the door frame of the anti-theft door are not on the same plane and are stuck? 4 The door leaf of the security door is sagging and the door leaf is stuck on the door frame? 5 The key turns Sometimes the upper lock point and the lower lock point do not return However, the above reasons can also be avoided, teach you a few tricks:

1 Change the lock cylinder lock body 2 Do not collide with the lock body and the lock point 3 Do not put oil and a small amount of lead powder in the lock cylinder 4 Always check whether the door frame is sagging If it sags, the adjustable screws on the door leaf can be adjusted? Usually you also need to maintain the anti-theft door, teach you some maintenance methods: 1. The screws on the hinges of the door body should be reinforced every three months, so as not to cause the door to sag after the screws are loosened, so that it is difficult to open the door due to scratching against the door frame.

2. Regularly add pencil end lubrication to the lock cylinder, which can make the key insertion and unplugging smoother, but do not use grease lubrication. If grease is dripped into the hole, it will mix with the iron filings caused by the key rubbing inside the cylinder, and the entire cylinder will be blocked within a month. 3. The screws on the lock plate and handle should also be strengthened regularly, but do not remove the lock without permission.

After all, the user is not a professional, and the installation after the lock is removed will inevitably cause gaps, errors or poor coordination of various parts, which may lead to door lock failure and other problems.

It's really not good to ask for help from the lock company, but I also have a trick, if your door lock is the kind of quick lock, use a steel bar to bend into an "L" shape, insert the doorknob on the inside of the door from the cat's eye position of the door, confirm that the handle is hooked, and lift it up, it's OK

How did you open the lock, brother.

The lock cylinder is stuck, haha, get a good night's sleep, and ask a friend to find the one who picks the lock tomorrow 200 yuan

There are several reasons and solutions for the security door to not open from the inside:

1. Due to the loosening of the safety bolt button inside the doorWhen closing the door, the force is too large, the safety bolt is shaken down, the lock cylinder can be turned with the original key, but the door can not be opened, you can find a lock company for repair.

2. The child accidentally hits the safety bolt at home, and will not open the safety bolt caused the person outside to use the key to open the lock, because the door lock is hit with the safety bolt or can not open the door.

3. The effect of external force on the lock cylinder outside the anti-theft door is not traceless and deliberately damaged, people with ulterior motives inject glue and foreign objects into the lock cylinder, use the technical opening tool to dial the lock plate to produce automatic locking, others deliberately destroy the internal bullet of the lock cylinder dislocation, will make the lock cylinder unable to open, clean up the foreign body, and add pencil powder can be opened with a key.

The principle of the security door

The anti-theft door is equipped with an anti-theft lock, which can resist abnormal opening under certain conditions within a certain period of time, has a certain safety protection performance and meets the corresponding anti-theft security level.

Generally speaking, the part of the lock body that can be controlled by the key on the outside can be opened if it is locked on the inside. In fact, many locks can be seen that there is a small lock inside the door, and there is no keyhole outside, so there is no way to open it outside. The electronic lock will be relatively better, it can be set up, and it can't be opened at all outside.

In this case, there are actually many methods, if you think these methods do not work or will not, then you can only ask the lock to come over.

1. When people are inside: find a small wire or a small hole in the neck of the grip, insert the flat tenon grip and pull it out at the same time, grasp the handle and pry open the cover after it is taken off, there are two fixing screws to turn it open, and when the lock body is pushed out and only the oblique tongue is left, then find a needle-nose pliers or a flat screwdriver, and the oblique tongue will be driven to the horizontal dial and do not let go, and it will bounce back after letting go, and then push the door open.

2. When people are outside: find a olecranon pliers or water pipe wrench, clamp the horn lock grip and twist it hard, grasp the handle and the lock cover to turn left and take it out, and then knock the lock body inward (because it cannot be pulled out, the lock body is stuck by the inner cover) You can see the oblique tongue, and then find a needle-nose pliers or a flat mouth driver, and drive the oblique tongue to the horizontal dial and do not let go, and it will bounce back after letting go, and then push the door open. In case of emergency, this method can be used, if the lock has failed, it is recommended to find a locksmith or call the police for help.

3. The child will not twist open when the child is locked inside, at this time you don't want to scream nervously, but will frighten the child, slowly induce him to open the door, induce him to turn counterclockwise (if you stand outside the door, facing the door, it is to turn to your right hand) If it is a five-section lock, some are pulled up and down, and pulled down.

4. If your home is a horn lock, causing the door lock to suddenly not open, it is likely that the lock diagonal tongue is out of hook and malfunctioning, then you can open the lock screw, repair the lock tongue, or change the lock, etc., you can open the door lock.

5. If it is an auxiliary lock, (most of them are installed in iron doors and Liuhua copper doors), the lock tongue or the fixed screws of the handle oblique tongue are loose and protruding, and the door frame cannot be opened. At this time, you can find a flat screwdriver, put the protruding screw from the door crack, and dial it back to position.

6. If the lock is stuck in a foreign object, it is difficult to twist the handle or key open, if the door is opened outward, the door can be pulled inward; If the door is open inward, you can push the door outward with force, which reduces the jamming force and allows the door to be easily twisted.

If your security door won't open, here are some possible solutions:

Confirm that the key is correct: Start by checking that the key in your hand is correct. If you're unsure, try using a spare key or contact a professional lock picker.

Spray lubricant on the cylinder: If the key does not fit smoothly into the cylinder, you can use lubricant to spray it on the cylinder and gently twist the key.

Use pliers or a wrench: If the cylinder is too tight to insert the key, use the pliers or wrench to gently grip the cylinder and try to rotate until it is unlocked.

Seek professional help: If you still can't open the security door after trying the above methods, it is recommended to seek a professional lock picking service. Do not attempt to force the door open by brute force, as this may result in damage to the door or security issues.

In order to protect your home, it is recommended that you change the key of the security door regularly and do not give the key to a stranger.

When it comes to security doors, I believe everyone is familiar with them, which can not only protect the property and personal safety of people at home, but also protect us from the wind and rain. However, over time, the security door will also have such and such problems. So what should I do if the security door can't be opened?

If the horn lock cannot be opened, it may be that the lock diagonal tongue is out of hook and malfunctioning, at this time, the lock screw is disassembled, and the lock tongue can be bent and repaired; If the auxiliary lock cannot be opened, it may be that the deadbolt or the oblique tongue fixing screw of the handle is loose and protruding, and the flattening screwdriver can be found to dial the protruding screw inward from the crack of the door to position; If the above methods can't be tried, it is recommended to find a special lockpicking company.

How to choose an automoatic door:

1. Appearance.

When buying an security door, the first thing to look at is whether the appearance details are exquisite and comfortable to the touch. There is also the thickness of the steel plate of the door body and the quality of the filling material inside.

2. Lock.

The quality of the lock directly affects the security performance of the security door. Whether it is a conventional key lock, a smart fingerprint lock, a password lock, etc., it is necessary to understand in advance, such as a smart lock, and also understand the emergency measures in the case of no power and induction failure. Observe the fastening state and effect of the lock body, and the quality and anti-theft ability of the good brand are stronger.

3. Hinge.

The hinge, also known as the hinge, is the hub used to connect the door leaf and the door frame. Generally, the maximum angle of hinge control door opening is 95-110 degrees, especially 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, 180 degrees, etc., and the door leaf is also relatively heavy, generally in 100 kilograms, so there are great requirements for the load-bearing capacity of the hinge.

4. Sealing strips.

The sealing strip of the security door is very important, with the effect of wear-resistant and shock-absorbing, and the sealing strip on the market has a variety of materials such as rubber, paper, metal, plastic, etc. Therefore, when purchasing, it is necessary to choose according to the fit of the sealing strip.

Summary: The above is for everyone to introduce the anti-theft door can not be opened what to do and how to choose the relevant content of the anti-theft door, I hope to help friends in need, if you still need to know more about the relevant knowledge in the later stage, welcome to pay attention to Qeeka Home information.

When the room is overheated, the security door expands by heat.

When the doors and windows of the room are closed in the event of a fire, the air is not smooth, and the indoor oxygen supply is insufficient, therefore, the fire develops slowly, and once the doors and windows are opened, a large amount of fresh air pours in, and the fire develops rapidly. At the same time, due to the convection of the air, the flames will rush outward, so in the event of a fire, the doors and windows cannot be opened casually.

The security door cannot be opened during the fire, and I analyze the following three reasons:

1. There is a problem with the installation of the security door, or the house settlement causes the security door to not be opened.

2. Anti-theft lock cylinder, lock body, panel or fingerprint lock have potential safety hazards.

3. The fire and high temperature caused the deformation of the security door, resulting in the failure of the security door to open.

Three reasons: the first reason is that you can't open the inside with the key inserted outside The second reason, the lock plate has the function of committing theft, that is, if you go out and twist it a little more, the lock plate will ring, if a thief enters the house, he can only jump out of the window, and the big thing can't be moved. The third reason is that there is a problem inside the lock cylinder!

Fill the hole with pencil ash or wash the cylinder with gasoline.

Equipped with an anti-theft lock, it can resist abnormal opening under certain conditions within a certain period of time, and has a certain safety protection performance and meets the corresponding anti-theft security level.

The full name of the security door is "security door". It combines anti-theft and security performance. According to the provisions of the "General Technical Conditions for Anti-theft Security Doors", qualified security doors cannot be pried open within 15 minutes by using ordinary hand tools such as chisels, screwdrivers, crowbars and portable power tools such as hand drills, or open an opening of 615 square centimeters on the door leaf, or open an opening of 38 square millimeters within a semicircle of 150 square millimeters of locking points.

And the locks used on the anti-theft door must be a special lock for the anti-theft door with anti-drilling function that has been tested and qualified by the testing center of the Ministry of Public Security. The anti-theft door can be made of different materials, but only the door that meets the standard test and receives the safety product production certificate can be called an anti-theft door.

It is mainly reflected in the intelligence of its key components (locks), including various electronic anti-theft locks that have begun to be widely used, such as fingerprints, passwords, IC card locks, etc. With the advancement of technology, in addition to replacing traditional mechanical locks with smart locks, the Internet of Things security door will also be combined with smart home systems with functions such as security, home appliance control, elderly and child care, etc., and can realize functions such as network alarm, monitoring, data transmission and remote control, which are the embodiment of intelligence.

What should I do if the anti-theft door can't be opened from the inside, first, it is due to which the safety bolt button inside the door is loose, and the safety bolt is shaken down when the door is closed, and the lock cylinder can be turned with the original key, but the door can not be opened. Second, there are people Li Zhaobi because someone is at home and has something to do at the door, so he first put up the safety bolt and forgot about it for a while; When the door was closed, the diagonal tongue of the lock forcibly closed the door without shrinking. Third, it is that there are ignorant children and elderly people with Alzheimer's disease at home who accidentally put the safety bolt on at home, and will not open the safety bolt, causing people outside to unlock the lock with a key, because the door lock is hit with the safety bolt or can not open the door.
