Also, if you change the locks that are different from the neighbor's locks, it will also attract the attention of the thief, who thinks that the house is rich. The best solution is to leave your original anti-theft lock (also known as a decorative lock from the developer) on the back of the door.

Add a remote control lock, this remote control lock is installed in the inside of the door, can be installed above, below, top, or bottom, only the back of the door can be installed, can be installed anywhere, there is no lock hole outside, thieves come to steal things, the chain can not be found, let alone open, usually go out, close the door, as long as the remote control can be locked, it only takes 1 second, more convenient than any lock, (fingerprint lock to open the door also takes about 4 seconds) remote control distance can reach 5-10 meters. The price is also cheaper than the fingerprint lock, it is a good choice, our home is installed with one, imported from South Korea, followed by changing the window, changing the window is just for the sake of beauty and sealing, and anti-theft has little to do with it, If you want to prevent theft, you can install an invisible anti-theft window, which is both beautiful and can pass the requirements of the property, This is all installed by my own family, Share your own experience, I hope it will help you, Hope.

Both of these are okay.

First of all, consumers should ask the seller to present the test qualification report of the relevant department when purchasing. The regular security door is marked with FAM, and the product packaging will indicate that the implementation standard is GB17565-1998. Marked with other implementation standards is the metal door, these products are playing "edge ball", avoiding the country's strict regulations on anti-theft doors, according to the enterprise standards of their own production.

Compared with the anti-theft door, many metal doors lack reinforcing plates around the door frame, door leaf and lock, the thickness of the steel plate is thin, the quality of the lock is poor, and the safety performance is not guaranteed.

Secondly, it is necessary to carefully check whether the lock is used by the public security department to test the special lock for anti-theft, and at the same time to see whether the lock has an anti-drilling function The lock is the most important part of the anti-theft door, so the mechanical anti-theft lock also has industry standards, which is mainly reflected in the anti-technical opening. Anti-technical opening refers to the ability to resist the use of special tools by a lock technician to open the lock. The security level is the level specified according to the different regulations of the technical indicators of the mechanical anti-theft lock and the degree of anti-vandalism ability.

Mechanical anti-theft locks of the normal protection level are indicated by the letter 'A'. The high protection level is indicated by the letter 'B', and it is recommended that users choose Class B anti-theft lock. Now there are many multi-directional locks for anti-theft, and its advantage is that not only the door lock is locked, but also the upper and lower crossbars can be inserted and locked, which greatly increases the anti-pry performance of the door.

Also, don't be greedy for small gains. When buying, it is not only necessary to choose a good quality lock, but also to install it appropriately, if you choose an inferior lock, the installation does not meet the specifications, and you do not pay attention to maintenance during use, it is likely that there will be a "stuck lock" or even a situation that cannot be opened. Some brands of anti-theft doors are equipped with an inferior lock, and ordinary anti-theft doors are expensive because they are equipped with a good lock.

The core thing of the security door is the lock cylinder, once the lock cylinder is damaged, the security of the door is lost. Next, let's take a look at how to buy a lock cylinder, right? 1.

Look at the "teeth" of the key. The more teeth, the deeper the teeth, the more complex the arrangement, the more difficult it is to open, and the better the anti-theft performance. 2.

Pick the lock and weigh two, one than the weight and the other look at the lock cylinder. The heavier the weight, the better the quality of the lock cylinder, the more beads inside the lock cylinder, and the better the anti-theft function. 3.

Choose the lock cylinder to see the color, than the color to see the workmanship. The lock cylinder of good quality is treated with electroplating, with smooth surface and bright color. Among them, the color of dark yellow is the copper core, which is relatively strong and has good anti-theft performance, the color of the lock cylinder is dull, and the color is gray and white with bubbles is zinc alloy, and the anti-theft performance is average.

4.The key is rotated and inserted into the lock cylinder is stuck in poor anti-theft performance, after the key is half inserted, rotate clockwise or counterclockwise with 5 to 7 minutes of force and continue to press the key into the lock mouth, the key that is stuck indicates that the lock cylinder has poor anti-theft performance, and the anti-theft effect is good when the lock cylinder is inserted smoothly in the semi-rotating state.

1. Quality requirements, the thickness of the steel plate of the qualified anti-theft security door frame should be, the thickness of the door body should generally be checked in the weight of the door body, generally more than 40kg, and the internal structure of the door body can be checked by removing the cat's eye, doorbell box or lock handle, etc., and the thickness of the steel plate of the door body should have several reinforcing steel skeletons, so that the front and rear panels of the door body are organically connected together to enhance the overall strength of the door body.

2. Process quality, pay special attention to check whether there are welding defects, such as open welding, unwelding, missing welding, etc. Look at whether the fit between the door leaf and the door frame is dense, whether the gap is uniform, whether the opening is flexible, and whether all joints are dense.

3. Lock inspection, qualified anti-theft doors are generally used by the public security department to pass the anti-theft special lock, at the same time, there should be a thickness of steel plate at the lock for protection. Now there are many anti-theft special locks are multi-directional locks, and its advantage is that not only the door lock is locked, but the upper and lower crossbars can be inserted and locked, and the door is fixed, which can increase the anti-pry performance of the door.

4, brand assurance, brand is the symbol of product quality and service, brand mainly refers to the product brand and dealer brand, in the market to buy anti-theft doors, it is best to buy in the regular large-scale home building materials city. When purchasing, you should also pay attention to the "FAM" mark of the security door, the name of the enterprise, the implementation of the standard, etc., and the door that meets the standard can be both safe and reliable.

1.Attention should be paid to the choice of home anti-theft locks, and try to choose locks from regular manufacturers, and the quality and safety are guaranteed.

2.Anti-theft lock deadbolt (bolt) its extension length: A-class anti-theft door extension length should not be less than 14 mm; Class B should not be less than 20 mm.

The shell of the anti-theft lock is generally made of steel plate with a thickness of not less than 2 mm or a material with a certain strength, and the fold and opening should be welded firmly or stamped as a whole.

3.Safety seems to be ineffective, but in fact, safety is the greatest benefit. It is best to install electronic alarms in households with conditions and place them within reach to give the alarm.

4.The lock cylinder is the core of the anti-theft lock, all the anti-theft locks have only one lock cylinder, as long as the lock cylinder is opened, all the lock points are opened. Special attention should be paid to check whether there are welding defects, such as open welding, unwelding, missing welding, slag inclusion and other phenomena It is reported that mechanical anti-theft door locks are divided into ordinary protection level (class A) and advanced protection level (class B).

Hopefully, the following answers will help you. In the face of a wide variety of products on the market, it has become difficult for consumers to choose a suitable smart door lock, and the following are my experience suggestions. 01 Lock cylinder level Whether it is a traditional door lock or a smart door lock, the lock cylinder is an important part of ensuring home security.

According to the national safety standards, the lock cylinder is divided into three levels: A, B and C, of which the A and B lock cylinders are less difficult to unlock and have poor security, and the C level is the highest level of safety specifications. Therefore, when choosing a smart door lock, it is very important to choose a lock cylinder above grade B. 02 Material selection When buying a smart door lock, the material is also a part that everyone can't ignore.

Generally speaking, the outer panel material of the smart door lock is mainly composed of rust steel, zinc alloy and copper material, zinc alloy is currently the most used material type for smart locks, with the characteristics of easy processing and easy molding, and the hardness and strength also meet the requirements for locks. 03 Multiple functions It is recommended that when you choose a smart door lock product, choose a door lock with alarm function, such as: low battery alarm, hijacking alarm, password error alarm, forbidden test alarm, anti-demolition alarm, etc., which is equivalent to adding another anti-theft door and increasing the security of the smart door lock.
