Car anti-theft

★Car theft prevention should be remembered

1. It is always better to have anti-theft measures than none. Adding a lock to the original car's anti-theft function is because car thieves are more afraid of trouble, and multiple protections will only make them give up in the end.

2. When purchasing a car, the anti-violence lock design should be an important factor in considering the car.

3. There is a saying that people who install car alarms seem to be far more interested in remote control door locks than anti-theft! However, the role of anti-theft devices cannot be ignored. It is worth noting that on rainy days and in noisy environments, you should pay more attention to the short beeping of the anti-theft device.

4. It is best not to install an anti-theft device on vehicles with electronic chip anti-theft.

5. GPS anti-theft effect is better, but the cost is higher. Currently, the most popular GPS systems in my country are anti-robbery and anti-theft systems, which are car anti-theft systems with network alarm functions. When a GPS system is installed, if the car is stolen or needs rescue, the system will automatically or manually send an alarm message.

★The secret of car theft tactics

1. The steering wheel lock cannot be locked. Many car owners like to use a steering wheel lock to lock the steering wheel, but such a lock is useless to "experienced" car thieves. The steering wheel lock is very strong, but it only requires a saw blade to cut four gaps in the steering wheel. The "anti-theft system" was destroyed.

2. Master key vs. marble lock. The pinball lock is very popular. The so-called pinball lock uses multiple pop-up pins in the lock to jam the bile so that it cannot be linked with the trigger switch mechanism behind it. But the master key almost solved everything. The hard homemade steel piece was forced into the keyhole, causing the lock cylinder to rotate and pry the lock open.

3. The anti-theft device does not prevent theft. Some people are complacent about installing an anti-theft device that is so sensitive that it will sound an alarm even when other cars are passing by or raindrops fall on the car. Little do they know that this will give car thieves a clue. First they tap the vehicle, causing a very brief alarm, and then slam the window...the anti-theft device vibrates again, picks up the alarm, and stops the alarm. The characteristics of anti-theft devices that are sensitive to raindrops and thunder are fully exploited, and some car thieves specialize in rainy days to commit crimes.

4. Copy the car owner’s identity. Generally speaking, top luxury cars are not just in vain, and of course it is also reflected in their anti-theft systems. Otherwise, if millions of cars are easily stolen, insurance companies may blacklist such cars. But a Mercedes-Benz and a BMW were still stolen, and the many mysteries set up by high-end technology and the many checkpoints set up were so vulnerable? The answer is no. If someone obtains the detailed personal information of the car owner through the dealer and prepares a legal key, it will be difficult for anyone to prevent it. (Jiang Yunhua Chen Wenjia)

Review of the anti-theft capabilities of mainstream models

The anti-theft capabilities have become one of the selling points of cars. Do you know the anti-theft capabilities of your car?

Although as the saying goes: "A key opens a lock." In fact, the problem of mutual door opening rate is still unavoidable until now. Regarding the mutual opening rate of the door locking system, my country's national regulations specifically stipulate that the keys used in the door locking system of each model produced by the manufacturer should include no less than 1,000 different combinations, that is, there must be no mutual opening among the 1,000 keys. Development happens. Nowadays, domestic cars, especially mid- to high-end cars, such as FAW-Volkswagen’s Audi A6, Shanghai GM’s Buick series, and Guangzhou Honda’s Accord series all meet this standard.

Domestic cars currently on the market include Audi A6, Passat B4, B5, Santana 2000 Era Superman, Santana Century Rookie, FAW-Volkswagen Bora, Jetta new interior series, and Hongqi series; imported models include Skoda Euro Asian and imported Honda, Volkswagen Beetle, Nissan Style A32, A33 and some models of Mercedes-Benz, BMW, Cadillac, Volvo, Opel, Ford, Toyota and Jaguar all come with computerized anti-theft systems.

■Xia Li The original car does not have any anti-theft measures: this kind of car is probably not a pleasure for car thieves to steal. Because to steal this kind of car, you usually only need to prepare tools such as a screwdriver and iron wire. You can easily use the gap in the door to lift the door lock button to open the door, connect the ignition wire, and your car will change ownership!

■Elysee, Picasso electronic electromagnetic digital response anti-theft system. The Elysee and Picasso have electronic electromagnetic digital response anti-theft systems that can automatically control the unlocking and locking of the anti-theft function. Compared with the keypad anti-theft system, the car owner does not need additional operations.

■Pario and Sienna series models of Palio and Sienna adopt FiatCodeⅡ anti-theft system. This system consists of four major components: key, key sensing unit, body computer, and engine computer. With the code II anti-theft system, even if a car thief is equipped with an identical key, it will not pass the inspection of the body computer, and thus will not be able to run the engine computer and drive away.

■The original anti-theft device of the Bora car uses each sensor to transmit the pulse signal that conforms to the original design to achieve the purpose of legal activation. When the car's internal monitoring computer does not get relevant information, it will default to illegal start, and the control unit will order the electronic ignition system, starting system, and fuel supply system to stop working, cut off fuel, and cut off power, making the car unable to start.

■Passat, POLO If a thief uses an illegal key (including a key prepared according to the original factory key) to start the car, the system will automatically lock the engine control unit and prevent the engine from starting. Even if the thief connects the ignition switch by himself , the result remains the same.

■Zhonghua Each key has a transmitting chip inside. When the key is inserted into the ignition switch, the chip transmits a signal to the transceiver coil, which is equivalent to an encrypted password. If the anti-theft controller identification code is incorrect, it will immediately instruct the engine computer board to cut off the fuel supply and ignition system, making the engine unable to start.

■The anti-theft security system equipped on the Audi A6 represents the world's most advanced intelligent anti-theft technology at the end of the 20th century. Its anti-theft security system includes: engine electronic anti-theft starter, steering column anti-pry protection lock, anti-copy password electronic chip key, anti-theft alarm device, door lock and trunk anti-pry protection system, fuel tank cap, car door and trunk, remote control opening Devices etc.

■Toyota Camry and Vios The new Camry 2.0, 2.4 and Vios GXL-i and GXL-s models are equipped with relatively advanced anti-theft systems. The anti-theft system installed on Camry 2.0 and 2.4 not only meets the general anti-theft function, but also uses an advanced smart password car key in the anti-theft system. Even if the car key is copied by others or the traditional car theft method is used, the car will not be able to be stolen. Start the vehicle. The Vios GXL-i and GXL-s models are equipped with the advanced TVSS electronic anti-theft system (referred to as Toyota Safety Protection System). When the car is locked with the keychain-shaped remote control, the TVSS system is activated at the same time. If the door is not opened with the remote control, the engine will not start and an alarm will sound.

■BMW 21-digit password can be adjusted independently. Since 1995, all vehicle systems have been equipped with smart anti-theft locks. This anti-theft lock uses the principle of a radar transceiver. Its characteristic is that a helical antenna is installed outside the ignition and a microchip is installed in the keyhole. When the key is turned, the antenna becomes a converter and supplies power to the microchip to display the password sequence. , if the order is met and the authorized identity is met, the door can be activated.
