It is not a bad thing to add more anti-theft means to the car. A survey in the United States is very thought-provoking. If every car in the world is equipped with 20 different anti-theft measures, then all car thieves will starve to death. What is said here is not that these thieves can't open the 20 locks on this car, but that these thieves don't have enough time to open them unless your car doesn't look at it for a month.

At present, there is no absolutely safe car in the world. Any kind of anti-theft device has the possibility of being cracked. However, with the passage of time, people have more and more innovative inventions in the automotive field, applying anti-theft technology to automobiles. It has also become more advanced with the emergence of a large number of car thieves, and it has also started a game in which the road and the devil compete with each other and have no end.

Car anti-theft mainly has various anti-theft products and original anti-theft devices. Car anti-theft products are mainly divided into two categories, mechanical anti-theft products and electronic anti-theft products. Mechanical anti-theft products include wheel locks, locks and steering wheel locks. Electronic anti-theft products range from ordinary electronic anti-theft devices to mobile phone remote control GSM and satellite positioning GSP. Below we will introduce the characteristics, advantages and disadvantages of each type of anti-theft products.

Mechanical anti-theft products

Wheel lock: As the name implies, the wheel lock is locked on the wheel, making the wheel unable to rotate for anti-theft purposes.

Advantages: The wheel lock is generally very bulky and huge, and it is almost impossible for the car thief to damage the wheel lock body. It is less likely that the wheel that locks the wheel lock will be removed from the wheel to drive the car away.

Disadvantages: The anti-theft performance of the wheel lock depends on the lock cylinder it uses. If the lock cylinder is a circular lock hole, a letter shape, a cross shape or other common keyhole, the wheel lock is not safe. Because these ordinary lock cylinders can be twisted open within a few seconds with special tools.

In addition, the wheel lock is used outdoors, wind and rain, and the lock cylinder is very close to the ground, the lock cylinder is easily damaged. For example, if the car is parked on the mud, after a heavy rain, the sand enters the lock cylinder, and the wheel lock is likely to be unable to open again.

Gearshift lock: There are two types of gearshift locks . One type requires riveting a steel plate on the car body, and a lock body like a normal padlock is fixed on the steel plate.

Advantages: The gear lever can be locked in the parking position to prevent the car from driving away. The gear lock is more convenient to use.

Disadvantages: insufficient security. For most cars, the car thief simply opens the front cover and pulls the gears from the front of the car to hang up and drive the car away.

Steering wheel lock: It is the most used anti-theft tool for car owners.

Advantages: It is cheap, it is not too troublesome to use, and gives the owner a pragmatic feeling after use. In addition, if there is an emergency, it can also be used as a weapon.

Disadvantages: The outer circle and the spokes of the steering wheel are made of plastic with a small aluminum alloy tube (about one centimeter in diameter and about one millimeter in wall thickness). With a one-foot long iron shear, you can easily cut the outer circle or the spokes of the steering wheel in seconds. Then remove the steering wheel lock from the incision and throw it away. The whole process takes only 6~60 seconds! If your steering wheel lock uses a circular keyhole or other common keyhole, it is even simpler. The thief uses a special tool to strongly twist the lock cylinder to open the lock. The speed is faster than you can unlock with a key.

The mechanical anti-theft product is the simplest and cheapest one on the market, the principle is to lock the steering wheel and the control pedal or the handle. The advantage is that the price is cheap and the installation is simple; the disadvantage is that the anti-theft is not thorough, the mechanical anti-theft device mainly plays the role of restricting the operation of the vehicle, and has limited help for the anti-theft, and it is difficult to resist the shovel, the hacksaw and the large scissors. Theft of heavy tools. But if the gangsters use a special unlocking tool or a highly corrosive chemical to erode the lock cylinder through the keyhole, stealing the car is only a matter of minutes. In addition, it is troublesome to disassemble each time.

Electronic anti-theft products

The so-called electronic anti-theft, in short, is to add electronic identification to the lock, unlocking the key all need to enter more than a dozen passwords of the car anti-theft method, it generally has remote control technology, is rapidly developed with the development of electronic technology An anti-theft method.

The electronic anti-theft system adds electronic anti-theft on the basis of the mechanical anti-theft device. In fact, it is to add the electronic identification code to the lock. It is necessary to input more than ten passwords for unlocking or keying. Mainly by locking ignition or starting to achieve the purpose of anti-theft. At present, there are three types of electronic anti-theft devices, such as insert type, button type and remote control type; PLC and iron general are mainstream brands;

Applicable objects: Vehicles that are not equipped with an electronic anti-theft system in the original model, especially those who are more cautious about safety issues;

Advantages: With anti-theft and audible alarm function, when the vehicle owner locks the door remotely, the alarm enters the warning state, and also has the safety warning function of the door not closed, the car-seeking function and the remote central locking function;

Disadvantages: In addition to the slightly higher price, the alarm sounds more falsely, often staged a "wolf is coming" farce, but also easily caused residents' resentment.
