Keyless Entry and Car Theft

Car theft is increasing and thieves have found new ways to gain access to vehicles. Keyless entry is among the most common methods.

The days of taking cars away by breaking windows and wiring them long gone. Now they can hack into the computer systems of vehicles in minutes.

Relay Attack

Since the introduction of the technology known as Push-to-Start millions of drivers have benefited from having the ability to start their car without reaching for keys. Unfortunately, the same convenience can make vehicles susceptible to theft. In particular thieves have been able to utilize a technique that is called the relay attack to steal cars within seconds. This technique makes use of an amplifier to capture and amplify the signal generated by the key fob of your car. It allows thieves to unlock the vehicle and drive off.

Relay attacks are a variation on an older technique called Man-in the-Middle Attacks. This type of attack is employed in cybersecurity to alter and intercept the communication between two entities without either party realizing it. In the case of a relay attack the attacker uses a device to capture the signal from the key fob in your car and transmits that signal to a different device located close to. The second device is able to open the door and begin the engine, effectively taking your vehicle away in a matter of minutes.

In order to carry out an attack via relay criminals need only an affordable, easily accessible device that can detect and amplify the signal emanating from your key fob. Usually, thieves work in pairs, with one holding the relay amplifier, and the other one standing near the victim's house. The thief swizzles the device in the direction of the home of the victim, and then tricks the car into thinking the key is close by.

Some experts suggest keeping your key fob in a metallic container, signal-blocking pouch or Faraday bag when not in use to avoid this type of theft. But it is a straightforward solution that has been shown to be ineffective against modern relay devices. A steering wheel lock is a better option, as it physically prevents the thief from steering the vehicle after it was stolen.

Many car makers have attempted to solve this problem by introducing features, such as secure keyless entry systems which employ cryptographic techniques with time-sensitive codes to defend against relay attacks. However, criminals have been able to develop devices that defeat these measures. This is why the race is on to discover a way to stop relay crime while preserving the convenient nature of keyless technology.

Hacking

A lot of new cars stolen with keyless entry come with keyless entry systems, which let drivers start and open their vehicle without the need for an actual button or key. However, these systems could be vulnerable to a new type of theft. The thieves could use electronic devices that copy the signal of the key fob and transmit it to an accomplice who is holding an electronic transmitter near the vehicle. The thief can then unlock the vehicle and then drive away. This is referred to as relay attack. It can be completed in 20 to 30 seconds according to AAA.

Thieves can often use inexpensive devices to imitate the wireless key fob signal to record it and send it to a partner. Then, when the victim presses their key fob to lock or open the car, the thief can pretend to be the legitimate owner by sending a response to the car stolen lost spare key's system that makes it think a genuine signal is being sent by the fob.

The more sophisticated thieves have designed devices that plug into the On-Board Diagnostics port (OBD), which is located usually beneath the steering wheel. This port permits mechanics to connect diagnostic tools. The criminal can download information from the car's computer and create an empty key fob that matches the car's specifications. Almost all vehicles are vulnerable to this kind of hacking.

Some thieves have used TikTok challenges as a way to teach people to make inexpensive amplifiers that boost the signal from the key fob, making it possible for an accomplice to open the door even when it is in the driveway. This has prompted companies such as Kia and Toyota to update their software which block this vulnerability.

Experts recommend that you keep your car keys stolen in a trunk or space that is far from home, so that a burglar can't easily access the keys. You can also purchase RFID pouches to protect the signal from misuse. Some of these pouches come with metal mesh linings, and are available at a low cost of around $10. Similar to your phone and computer, it's important to keep the software on your car stolen Keyless Entry up-to-date.

Radio Frequency Identification (RFID) Cards

The most recent car key fobs use radio signals to communicate with the vehicle and allow owners to unlock their vehicles and start them without needing to touch the key. These new technologies increase the likelihood of theft. The signal from a keyfob's sensor can be captured if the fob is left on a table near the front door or in the wallet. Then, they can copy it using simple devices called emulators, that are the size of handheld consoles. Once they have it, they can open the car and drive it away in just a few minutes.

The crooks typically operate in pairs. One of them will be outside your house holding a relay amplifier and the other one will hold the device that collects the signal from the key fob. The thieves can then amplify the signal to make it strong enough to evade security systems in your car.

Another technique that is popular is jamming the communication between the keyfob and the vehicle. Thieves accomplish this by using signal jammers that emit the same radio frequencies as a key fob. This muddles the signal, which prevents it from being interpreted by the car, which stops the lock button from working.

As thieves become more sophisticated in their methods, auto dealers need to be on guard to protect their inventory. Dealerships should put up high-security perimeter fences, with cameras and secure entrances to ensure that thieves cannot drive flatbeds on cars at night. They should also train employees on proper key handling practices that include locking vehicles securely and keeping them in a secure location when not being used.

Luckily technology is working to combat these new thieves and stop car thefts. For instance, some car makers are developing key fobs that use active RFID chips with frequency-hopping technology to make it more difficult for thieves to amplify the signal coming from the key. Faraday cages are another way to block signals from a keyfob's signal to the car. Other defences include etching the last seven numbers of your Vehicle Identification Number (VIN) onto the headlights, windows and mirrors to prevent re-sale or re-use of your vehicle.

Theft of VIN

Keyless entry is convenient, but it also opens up new possibilities for thieves to steal vehicles. Your car will unlock doors and start its engine when it detects the signal transmitted by your wireless remote or key fob. If the signal isn't recognised the car keys stolen no spare will lock, but it will not start. This is due to the fact that you have to have the key in your hands to press a button on the fob to start the starter.

This is the reason it's crucial to keep your remote and key fob out of sight even when your car is in a parking spot. Criminals could use a tiny transmitter device to detect your signal and hijack it. He will then be able to unlock your door without touching the ignition or the key.

In certain instances criminals are able to swap out the vehicle's VIN and title to conceal their involvement in the stolen vehicle. This practice is known as VIN switching and is on increasing. Typically, crooks will buy a damaged car at auction or from police departments and then modify the VIN. They then use the legal VIN of a different make and model to get the new title and registration, and then sell it to unsuspecting buyers.

A popular theft deterrent is to have your VIN etched into the windshield of your car. There are several firms that offer kits for this, and in certain areas, the police department or AAA offers this service for free. It might seem counterintuitive to believe that etching can deter thieves. After all, it makes it more difficult for dealers to buy your my car was stolen with the keys in it. However, a professional thief knows that etching will be a significant stumbling block and will likely avoid taking your car.

The NICB offers a no-cost VINCheck online tool to determine if your car has been reported stolen or salvaged but not yet recovered. The service requires an active VIN to perform a search and is accessible on their website. In addition, a wide range of products to deter crime are available for your car that include audible and visible devices that act as a deterrent to criminals. These include the locking of your steering wheel and alarms, as well as window engraving.
