How to Protect Your Keyless Car From Theft

While keyless entry systems offer convenience for drivers, they have also introduced a new vulnerability for car thieves to exploit.

Studies have shown that keyless cars are easier to steal compared to traditional car keys.

A Guardian article highlights the issue – and warns that insurance premiums are on the rise because of the growing number of keyless car thefts.

It found that thieves could steal a Hyundai electric car in just 20 seconds.

Here, we look at the reasons behind this increased vulnerability and why a tracker with immobilisation features is a valuable investment for keyless car owners.

How keyless entry systems work

First, we need to understand how keyless car entry systems work. 

Keyless entry systems, also known as proximity entry systems, use a transponder which is usually in a key fob to transmit a radio signal to the car. 

When the fob is within a certain range of the car, the car’s security system recognises the signal and unlocks the doors. 

The engine can then be started by pushing a button on the dashboard.

How thieves exploit keyless entry systems

Understanding that the keyless entry system works by using a radio signal to disable the car’s security, thieves have developed several techniques to exploit this – here are some of the most common methods:

• Relay attack: You’ll hear this term a lot and this method involves using a device that amplifies the signal from the key fob and relays it to the car, even if the fob is some distance away, for example, inside the owner’s home. Once the signal is received, the car unlocks and allows the thief to start the engine
• Headlight hacking: Some thieves target newer cars with keyless entry systems that are linked to the headlights. By cleverly manipulating the headlights with a diagnostic tool, they can gain access to the electronic systems and steal the vehicle
• Signal blocking: For this method, thieves use a signal-blocking device to prevent the car’s security system from receiving the signal from the key fob. This disables the key fob and allows the thief to break into the car using traditional methods
• Code grabbing: This is a more sophisticated technique that involves using specialised equipment to capture the code transmitted between the key fob and the car. The captured code can then be used to unlock the car and start the engine.

UK company TrackerTeam said that relay devices are currently the most common way that thieves are stealing vehicles. Relay devices typically allow a vehicle to be stolen in around 60 seconds if a thief can obtain the signal from the vehicle owner’s keys.

Other car theft threats to consider

• Malware attacks: Although less common, some keyless entry systems are susceptible to malware attacks that infect the car’s software
• Social: The thief may trick the car owner into giving them access to the car, for example, by posing as a mechanic or roadside assistance worker and convincing them to hand over their key fob

Why trackers with immobilisation are essential for keyless cars

While car manufacturers are constantly working to improve the security of keyless entry systems, these systems are still vulnerable to theft. 

Here’s where a tracker with immobilisation features comes in:

• Recovery: If your car is stolen, a tracker allows you and the police to locate it quickly and efficiently. This can significantly increase the chances of getting your car back
• Immobilisation: Some trackers come with immobilisation features that allow you to remotely disable the car’s engine. This can prevent the thief from driving the car away even if they manage to steal it
• Deterrence: Knowing that your car is equipped with a tracker can deter thieves from targeting it in the first place. 

Choosing the right tracker with immobilisation

Since using a tracker with immobilisation features can be an effective way to prevent theft, consider these issues before investing in one:

• Features: Look for a tracker that offers real-time GPS tracking, allowing you to pinpoint your car’s location in case of theft. Immobilisation features that enable remote engine shutdown can be a game-changer. Also, some trackers offer features like tow-away alerts and 24/7 support
• Installation: Choose a professional installer with a good reputation to ensure the tracker functions optimally and remains hidden from potential thieves
• Subscription fees: Most trackers require a monthly subscription fee for the service to function so compare options and choose a plan that fits your budget
• Compatibility: Ensure the tracker is compatible with your specific make and model.

Why use a tracker with immobilisation?

While keyless entry systems offer convenience, they also introduce new security risks so by investing in a tracker with immobilisation features, you can significantly reduce the risk of your car being stolen.

Plus, you’ll increase your chances of recovering it if it is stolen.

Additional security measures

In addition to the measures already discussed, there are several other steps keyless car owners can take to enhance the security of their vehicles.

Physical Security Measures

Using traditional physical security measures can provide an added layer of protection. Steering wheel locks, pedal locks, and gear locks are inexpensive and effective deterrents against theft. These devices make it significantly more difficult for thieves to drive the car away, buying valuable time and potentially causing them to abandon their attempt.

Faraday Bags

Faraday bags, also known as signal-blocking pouches, can be used to store your key fob when it is not in use. These bags block the radio signal emitted by the key fob, preventing thieves from amplifying or relaying the signal to gain access to your car. While it may seem inconvenient, using a Faraday bag is a simple and affordable way to protect your vehicle from relay attacks.

Regular Software Updates

Car manufacturers frequently release software updates to fix vulnerabilities and improve the security of keyless entry systems. Regularly check with your dealer or manufacturer for the latest updates and have them installed as soon as they become available.

By combining these additional security measures with a tracker and immobilisation system, you can maximize the security of your vehicle. The more layers of protection you implement, the harder it becomes for thieves to succeed.
