How to choose car anti-theft products

Car anti-theft products are mainly divided into two categories, electronic anti-theft products and mechanical anti-theft products. Electronic anti-theft products range from ordinary electronic anti-theft devices to mobile phone remote control GSM and satellite positioning GSP. Most of the electronic anti-theft products use the remote control, so it is very convenient to use. However, the criminals can also easily receive the signal from the remote control, and then copy the same signal to easily release the electronic anti-theft system on the vehicle. Therefore, the advanced scrolling code anti-theft system must be selected, that is, the number of signals sent by the remote controller is different each time, so that the criminals can no longer use the simple method of receiving and copying signals to unlock the anti-theft system. However, advanced and sophisticated electronic anti-theft products will be cracked, and criminals will use the Internet as a decoder or software to sell to car thieves across the country. The car thief does not need much cultural and electronic knowledge, and can easily use the purchased decoder to crack the car electronic anti-theft system and drive the car away (the decoder of the special car system only needs 500 yuan, the decoder for any model only needs Thousands of dollars). Therefore, it is best to use both electronic anti-theft products and mechanical anti-theft products.

Mechanical anti-theft products mainly include wheel locks, gear locks and steering wheel locks. As the name suggests, the wheel lock is locked on the wheel, making the wheel unable to rotate for anti-theft purposes. Wheel locks are generally very bulky and huge, and it is almost impossible for a 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. Therefore, 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 straight 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, the wind blows the rain, and the lock core is very close to the ground, and the sand dust is easy to enter the lock core to damage the mans. 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. Therefore, when using the wheel lock, it is necessary to use a new type of lock cylinder, such as a lock core with a circular key hole; and, there must be a dust protection cover on the key hole.

There are two types of gear shift locks. One type requires riveting a steel plate on the vehicle body, and a lock body like a normal padlock is fixed on the steel plate. The U-shaped lock locks the gear lever in the parked position to prevent the car from driving away. This type of gear lock is rarely used at present. Because the owner is bored on the gearbox, it is easy to cause dust or water in the gearbox and damage the gearbox. The new gear shifter does not require drilling holes in the car body, but it is necessary to change the gear bar of the original car. The gear lock is more convenient to use, but for most cars, the car thief only needs to open the front cover and push the gear block from the front of the car to hang up and drive the car away. Therefore, when using the gear shift lock, it is best to consult the car mechanic. The gear lock to be used can prevent the car thief from pulling the upper gear from the front of the car to drive the car away.

Steering wheel lock is the most used anti-theft tool for car owners. The main reason is that it is cheap, it is not too troublesome to use, and gives the owner a pragmatic feeling after use: I think that the steering wheel lock is locked, and the car thief will steal the car without the steering wheel lock and will not patronize my car. But this feeling is often wrong. Although some steering wheel locks may be anti-saw and anti-scissor, the car thief will not be so stupid to cut the steering wheel lock, they will cut the weak steering wheel and remove the steering wheel lock from the incision. The whole process takes only a few seconds to tens of seconds! If your car is new and beautiful, will the car thief care about these tens of seconds?

Therefore, when using the steering wheel lock, it is necessary to see not only whether the lock is anti-saw and anti-scissor, but also whether the lock cylinder is protected against the universal key, and whether the lock can effectively protect the steering wheel, so that the car thief cannot use the saw to cut the steering wheel. The steering wheel lock is removed from the slit. The steering wheel lock that really acts as an anti-theft, it must protect the steering wheel, so that the car thief can not easily and quickly cut the steering wheel and remove the anti-theft lock. There are such steering wheel locks on the market, for example, the British Autolok steering wheel lock, which can cover half of the steering wheel when the lock is opened. But the price is also very expensive, so the market is rarely available.

The most popular steering wheel lock in Taiwan is a combination of a T-type steering wheel lock or a telescopic top hook lock that fits against the instrument panel and a titanium alloy plate. The titanium alloy plate covers about 2/5 of the steering wheel, and then the T-type steering wheel lock or telescopic top hook lock is locked through the hole in the titanium alloy plate and locked on the steering wheel, so if the T-type steering wheel lock is not released first or The telescopic top hook lock, the titanium alloy plate is also not possible to remove from the steering wheel. Since the titanium alloy plate covers about 2/5 of the steering wheel, the thief cannot remove the steering wheel lock from the front (seat direction) and can remove the steering wheel lock (but still from the back - dashboard direction - sawing the steering wheel). Titanium alloy sheets can be high in strength and light in weight, but they are expensive.

At present, the Singapore-based technology that is popular in China, the armored car anti-theft lock produced in Guangzhou may be the steering wheel lock with the highest anti-theft performance. Its front and rear steel sheets cover the rim and the spokes of the steering wheel, so that the thief can remove the armor lock from the front and back and in any direction without destroying the steering wheel at the lock. This solves the fatal flaw of the steering wheel lock; the steering wheel lock can be easily removed by simply cutting the steering wheel.

For new cars, it is best to use anti-theft products that do not need to be modified or modified. Because in the case of quality claims during the warranty period, the car dealers often use the car has been modified or modified as a reason for refusal. Steering wheel locks with high anti-theft performance should be the best choice, as the steering wheel lock does not require modification or modification of the car.

For vehicles equipped with an advanced anti-theft system, the steering wheel lock with high anti-theft performance should also be used when parking in a less secure place. Because the car is in maintenance, the remote control, the car key are all handed over to the twins. If you encounter someone with a bad heart, it is very easy to copy your remote control and car key.

Compared with other anti-theft products, the biggest advantage of the steering wheel lock with high anti-theft performance may be its deterrent effect on the car thief. Since the steering wheel lock is placed in the most conspicuous place in the car, the car thief will find it difficult to retreat when he sees it, and instead chooses other easy-to-start cars instead of patronizing your car. This point is very important. If the car uses other types of anti-theft systems, such as gear locks or other circuits or throttle locks, but the car thief does not know before the start, enter the car and drill and knock, make the car look unrecognizable, even if the car has not lost The loss is not small. Therefore, the steering wheel lock with high anti-theft performance is irreplaceable for the deterrent effect of the car thief. Therefore, it is recommended that the owner, when parking in a less secure place or parking for a long time, should use a steering wheel lock with high anti-theft performance.
