One is the digital chip, and the other is a separate remote control. Its basic principle is to lock the car start control system or lock the car's motor, circuit and oil circuit, can't start the car without the chip key, the digitized password has a very low code rate, and the chip and car key should be used at the same time. ,Indispensable. It really plays the role of vehicle anti-theft, and the safety is quite high. The same model, each car has a matching password, and the performance is very guaranteed. However, there is a disadvantage that if the key is lost, it is more troublesome. The rematch may have to wait for a while, because it is necessary to contact the manufacturer directly through the service store, and it may be re-allocated, and the cost will be higher. Experts suggest that it is best to use the chip together with the remote control, which will increase the anti-theft performance of the car.

Steering wheel self-locking anti-theft: simple and sturdy. According to experts, the advantage of this steering wheel self-locking anti-theft device is that it is more convenient to operate and does not affect the appearance of the car itself. The possibility of using the car is relatively small, there will be no loss, and the anti-theft performance is better. However, for those who are more skilled in stealing the car, the anti-theft performance is not as good as the anti-theft of the chip. The disadvantage is that if it is damaged, it is more troublesome to repair, the workload is larger, and it takes more time, but the cost is not very high. Generally, it can be fixed for several hundred yuan.

Mechanical add-on lock: deterrent effect. There are two types of mechanical mounting locks, which are T-locks attached to the steering wheel and added gear locks. The average car owner will choose to use this. Experts believe that its advantage is that from the outside of the car can directly see the lock, generally in the case of easy to be found, the car thief will not go to the exclusion of a car lock, you can see this mechanical anti-theft The device can act as a deterrent to stealing a car thief. And even if the key is lost, it is more convenient. This lock can be replaced between 100-200 yuan. The disadvantage is that the anti-theft performance is general, the lock performance of the original car is not as high, and the configuration and principle of the lock is almost the same. Regardless of the model, if the car thief will open a lock, then all will open. .

Oil circuit dark lock: targeted. The anti-theft device is mainly an anti-theft system designed by a professional for a certain vehicle. Its principle is to change the line of the original car through a switch control circuit in the car. The advantage is that the anti-theft switch can be set in the place that the owner wants according to different consumption requirements of different levels of people, there is no universality, more targeted, and it is not easy to be discovered, the cost is small, and there is no loss. problem. The disadvantage is that for car thieves who understand the principle of this brand of oil circuit, the removal will be more convenient, of course, this involves a technical problem.

GPS network security: The name is loud but not practical. The GPS satellite positioning car anti-theft system belongs to the network anti-theft device. It mainly relies on locking ignition or starting to achieve the anti-theft purpose. At the same time, the GPS satellite positioning system can also transmit the alarm information and the location of the alarm vehicle to the alarm center silently. Experts reminded that the name of this anti-theft technology is very loud, although it has the function of anti-theft, but it is not very practical to use, and the price is expensive, the actual function is not big. Alarms are often issued by satellite positioning when the vehicle is in danger, and foreign countries are quite developed in this technology. For example, foreign satellite positioning is accurate to every 1 mm, while domestic technology can only detect 100 meters. The difference is obvious.

Other ordinary anti-theft devices: low security. The principle of this type of lock is to control the circuit of the original car, including the door, by retrofitting. However, the anti-theft performance is poor, the cancellation takes only a few seconds, and there is universality, and the overall anti-theft function is easy to fail. Experts remind all car owners not to abandon the safety of vehicles in order to facilitate the convenience of the map. It is said that it is an anti-theft device. In fact, it only functions as a remote control. Although it is a bit convenient to use, it is easy to falsely report failure.

Some systems add a security feature that turns on the internal car lights when the system is disarmed, allowing safe access. The zone disturbance sensor can alarm any movement in the car, and even if the car battery is de-energized, it can be armed with a backup battery retention system. There are many factors to consider when purchasing a car anti-theft system. If necessary, consider adding a car reversing sensor.

Frequent false positives, severely disturbing the people, may be too high sensitivity at the factory, and it is not excluded that some car owners think that the higher the sensitivity, the higher the artificial height. Car owners who have found similar problems can go to 4S shop, car beauty company, car service center, and ask professionals to reduce the sensitivity; the owner can also choose two-way alarm, the alarm will ring, and the remote control will vibrate or send out.

In addition, installing an alarm can also bring a series of drawbacks. In the process of installing an alarm, it will inevitably move to the oil circuit, which may affect the line and thus reduce the performance of the vehicle. Therefore, many auto manufacturers have clearly stipulated that once the vehicle is equipped with an alarm, no claims or warranty will be awarded even if there are related problems within the warranty period.

In general, for owners who have installed car alarms, try not to adjust the sensitivity of the alarm too high to avoid unnecessary disturbances.
