Sophisticated car theft technology
As automotive technology continues to advance, most new cars use wireless smart keys and push-button start instead of traditional metal keys.
The smart key system sends a short-range signal so that when the driver approaches the car, it automatically unlocks the doors. This saves the driver the trouble of having to pull out the key while his hands are full. But the technology also makes things easier for thieves.
The wireless key will continuously emit a signal even when not in use. At this time, even though the key is kept indoors and away from the car, thieves can still easily steal the car without any effort.
Thieves can use high-tech equipment to steal cars.
They would use a handheld device that could pick up the short-range signal from a smart key in a home or parking lot, then relay that signal back to a transmitter that could replicate the signal.
Officials have called on automakers to mitigate the security vulnerabilities and warn owners about the risks.
Although in Vietnam, thefts using such high-tech devices are not common. However, in the world , in countries like the UK or the US, every year there are thousands of car thefts related to high-tech devices.
How to avoid high-tech thieves
A simple but effective way to deter high-tech car thieves is to use signal-blocking key fobs. They are lined with a conductive metal mesh that blocks the transmission of electromagnetic signals.
These bags are inexpensive, and you can also buy boxes that do the same thing. But experts recommend testing them out to make sure they work.
Simply place your smart key inside and approach your car. If the doors don't unlock automatically, the signal is being blocked.
It is important to remember to use it whenever you leave your car and don't forget to keep all of your car's smart keys inside your pocket.
Owners can also try the traditional solution of using a physical lock. The lock is a disc or long bar that clamps onto the steering wheel, making it difficult to steer. There is also a version that locks the gear lever to prevent the car from moving while in gear.
Physical locks will make the car look more secure.
Some police forces recommend using them to make your car look more secure. The reason is that thieves may be deterred from trying to get past the second lock and instead turn their attention to an easier target. The downside is that it takes extra time for the driver to attach or remove it.
For many cars, owners can disable the wireless setting so that the door cannot be opened remotely. For Ford, Honda, or Audi models, this can be done through the touchscreen menu.
Some other manufacturers will allow direct key manipulation, like Toyota, which can temporarily turn off the signal by holding down the key's lock button while pressing the unlock button twice.
If done correctly, the key's indicator light will flash four times. Then when you use it again, simply press any button and the remote unlock feature will be re-enabled.
This method will vary depending on the make and model of your vehicle, so consult your vehicle's owner's manual for the exact procedure.
If buying a used car, some experts also recommend reprogramming the key, in case the previous owner kept one of the smart keys.
