How Do Keyless Cars Get Stolen?

The introductions draw your reader into the textual and the analytical space of the paper. They do this by stating the topic of your essay about (i.e. your thesis).

Video footage from front-door security cameras shows burglars using devices that record signals from key fobs left on tables or in the pockets of a purse or bag, and relay signals to the car to unlock and start it.

Relay Theft

Modern cars that are keyless are designed to make life easier for us by allowing us to lock or unlock, and even start the car without needing to insert the key. Unfortunately, criminals are now using this exact technology against us in the form of a new method called'relay theft'.

Two thieves work together to achieve this. One of them is near your home with a device that can boost the signal from your key fob, which is later relayed to another criminal who is positioned near the vehicle. The stolen car key reprogramming signal tricks the car's computer to think that the actual key fob is in close proximity which allows thieves to gain entry and unlock the vehicle. The criminal can then use their devices to begin the engine and drive away.

The good news is that a lot of the newest automobile manufacturers are adopting preventative measures to combat this type of crime. Mercedes for instance, has developed a motion-sensor key fob that will go into sleep mode for 40 seconds after activation to guard against relay attacks. Other car companies have also created ways to protect their owners' vehicles from relay attacks. Kia, for example offers its own faraday bag that helps block the signal of the vehicle. Other manufacturers also offer features that allow car owners to block keyless entry or install an electronic tracking system to protect their vehicle from being taken away.

Professional criminals and Internet thieves gangs can use relay attack tools. They typically target desirable car and van brands. Unfortunately, many car security systems do not detect the crime because a physical break-in is required.

As the increase in car thefts and we must be aware that this new type of crime is becoming more prevalent. While no method can guarantee that your car keys stolen from unlocked house will not be taken away, combining a variety of methods will greatly reduce the risk. You can take steps like placing your keys stolen in metal containers or a Faraday bag to shield the signal or removing keyless entry.

Signal Jamming

It is important to understand how a car is stolen car key. It's not as easy as slamming the window and hotwiring, as thieves can now steal keyless cars using technology that can bypass the car's security systems.

The latest method of stealing a car is called 'relay theft'. It's the use of electronic devices to collect the signal from a car owner's fob, then transmit it to another device located near the vehicle, luring it into thinking the owner is nearby and opening up the door and then starting the engine. It can be done in as short as 60 seconds, according to security experts.

Relay thefts are so prevalent that some manufacturers have upgraded their systems to combat them. It is essential to have the most current security system in your car and to stay up-to-date.

One method to prevent this kind of crime is to secure your key fobs with something called Faraday pouches, or boxes. These pouches and boxes are lined with a metallic mesh that is conductive to block the transmission of electromagnetic signals, making it more difficult for thieves to take your car. They are available at most hardware stores, and on the internet, at a reasonable cost. Experts suggest you test them before buying to ensure they function.

If you don't have one, you can also try locking your car manually. However, always ensure that it's locked before you walk away. You should also look around your immediate surroundings to see if anyone else is still around. If a criminal thinks they've been observed then they'll likely move on.

It is also recommended to park your car in a secure garage or on a street that is not directly adjacent to your home. This will prevent thieves from capturing and amplifying the signal from your electronic devices at home to gain access to your car. Parking too close to a vehicle could also trigger the same issue.

Reprogramming

Modern vehicles come with keyless ignition systems that use wireless remotes to unlock the car and start it. This technology is designed to make it easier for drivers and passengers to unlock and start their vehicles. However it also creates opportunities for thieves. The theft of an unlocked vehicle is more frequent than ever before.

Instead of smashing through windows to gain entry and gain entry, thieves can now employ simple tools and technology to clone the signal sent from your key fob. They accomplish this by amplifying the signal which then overrides the car's computer to unlock and start it. This is referred to as a relay attack and it is the easiest method of stealing a car that has keys-less entry systems.

Relay attacks can happen in a variety of ways, but they generally involve two individuals working together. One person will be near the vehicle in question with a device that can receive the signal from the key fob and amplify it. The other will be near the house and transmit the amplified signal to the key fob, which then signalizes the vehicle to unlock and begin. The criminals will then be able to escape in the car.

Researchers have been able, by extending the range of the key fob's signal to block relay attacks. This is the reason it's so important to keep your key fob safe from your home and place it in a Faraday case, or some other type of blocking device for signals, when you're not using it.

Hacking into the diagnostics port is a different method to steal keys from a vehicle. These ports, which are located in the front footwells of most vehicles allow mechanics to connect a diagnostic device to the vehicle's computer. Hackers have devised devices that can plug into this port, start the vehicle's software, and then program a blank key fob. This method is more sophisticated and requires expertise in electronics. However, thieves who are tech-savvy have already utilized it to steal cars.

Whether they're using a jamming device or a tool for reprogramming that allows thieves to unlock and steal newer car models that aren't covered by traditional security measures. If you're a dealership owner, it's important to give your employees training on how to stay away from these tactics.

Using Transponder Devices

The key fob transmits an alert to the vehicle to unlock and begin. However, thieves can use an cheap handheld device to amplify that signal which allows them to gain entry inside the vehicle and drive off. This is known as signal relaying and is one of the most common methods that modern vehicles are stolen. It can be accomplished in a matter of 60 seconds for the majority of thieves. Most of the time, thieves operate in pairs. One of them will be in front of the transmitter that picks up the transmission from the key, while the other is walking through the walls of your house with the relay amplifier, looking for a faint signal sent by your car's fob. If they find the signal, thieves can clone it and transmit it to a transmitter so that your car can replicate it.

Another technique is to block the signals that the key fob transmits to the vehicle. This is also a common practice, and it can be extremely difficult to stop. This is why it's crucial to keep your key fobs away from view when you're not using them.

Some thieves can even use sophisticated hacking devices to infiltrate the system that locks and starts the engine. These devices are available on Amazon and eBay for less than $100, and a few of them can be used for up to 50 feet away from the key fob. These devices connect to your vehicle's onboard diagnostic port, and then boot up software that reprograms a blank key to unlock and start the vehicle.

If you're a dealership owner it is imperative to do everything you can to prevent these kinds of crimes from happening on your property. Install fences that block all entrances after hours and educate your employees on the best methods for keeping key fobs in storage and returning them at the end of their workday.

Experts believe that a new method of theft will become more popular as more cars are designed to communicate with drivers via apps on their phones. This kind of theft is already becoming more frequent and could get more serious in the future. If thieves gain access to your phone, they can make use of it to reprogram your keys. This would bypass the immobilizer that stops your car from starting when the wrong electronic keys are present.
