Learn How Smart Keys Compromise Your Car's Security and What You Can Do About It

In today’s fast-paced world, smart keys promise convenience and ease. However, this modern technology carries significant risks that many car owners don't consider. Keyless car theft has become an alarming trend, reports show a 150% increase in vehicle thefts involving smart keys over the past few years. Understanding these dangers and how smart keys can undermine vehicle security is essential for every driver and vehicle owner. This post explores the risks related to smart keys and offers steps to enhance your car's safety.

The Rise of Keyless Car Theft

With smart key technology gaining traction, keyless car theft has also surged dramatically. Thieves have developed a method called a relay attack, which takes advantage of the signals emitted by smart keys. This technology allows them to unlock and then start vehicles without ever needing the physical key, circumventing outdated security measures.

Here's how it works: a thief uses two devices—one close to the original key (often near the owner's home) and another close to the car. The first device captures the signal from the smart key, while the second one relays it to the car. This manipulation tricks the vehicle into believing the key is nearby. According to the Office for National Statistics, incidents of keyless car theft jumped by 36% between 2020 and 2021, highlighting just how prevalent this issue has become.

It’s critical for car owners to be aware that while smart keys offer convenience, they also introduce vulnerabilities that can compromise vehicle security.

How Smart Keys Work

Smart keys use radio frequency identification (RFID) technology, connecting wirelessly with a vehicle when within its proximity. When the key is close enough, it automatically unlocks the doors and starts the engine. However, these wireless signals are susceptible to interception, making them attractive targets for thieves.

The continuous broadcasting of signals from many smart keys presents an additional risk. Estimates suggest that nearly 40% of all vehicles manufactured in recent years are equipped with this technology and few owners know how easy it is for criminals to exploit these signals.

The Vulnerabilities of Smart Keys -- Your Car's Security

Even though smart keys provide valuable convenience, several vulnerabilities put vehicle security at risk:

Signal Interception

The wireless technology behind smart keys can be intercepted effortlessly. Thieves can buy inexpensive tools online that amplify signals emitted by smart keys, effectively bypassing traditional immobiliser security protocols. A study from the automotive security firm CXO revealed that more than 40% of keyless vehicles have outdated software, making them easy targets.

Lack of Physical Security

Traditional keys require physical contact, meaning they can’t be used without being present. In contrast, the electronic nature of smart keys relies solely on wireless signals, making it simpler for thieves to steal a vehicle without needing the key to be there physically.

Vulnerable to Hacking

As automotive technology evolves, so do the tactics used by criminals. Hackers can exploit software weaknesses in smart key systems, gaining unauthorised access and even tracking vehicle movements. Reports indicate that keyless entry systems can be compromised through methods that require minimal technical skills, making it crucial for vehicle owners to act. Mobile key solutions offer reliable security upgrades to mitigate the risks posed by this new smart key technology. 

Practical Tips to Enhance Vehicle Security

While the vulnerabilities associated with smart keys are alarming, there are straightforward steps that drivers can employ to strengthen their vehicle's defenses against keyless car theft:

Use a Faraday Key Safe

A Faraday key safe is an excellent investment for blocking electromagnetic signals. By storing your smart key in a Faraday pouch when not in use, you can make it near impossible for thieves to capture its signal. Research shows that vehicles equipped with this simple protective measure experience a 80% reduction in unauthorised access.

Opt for Aftermarket Immobilisers

Installing an aftermarket immobiliser provides an additional layer of security. These devices make it extremely harder for thieves to start your vehicle, even if they successfully bypass the smart key system or get hold of your keys. Mobile key solutions offer the industry leading Can-Phantom immobiliser system -  This system uses the existing buttons and switches of your vehicle to operate and blocks the starting of a vehicle until the correct sequence of buttons have been pressed. (like a pin number for a bank card)

Implement GPS Trackers

If your car is stolen, a GPS tracker can aid in a fast recovery. Many modern GPS trackers offer real-time location data, which can be invaluable to the police when trying to locate a stolen vehicle. Statistics indicate that vehicles with GPS tracking systems have a recovery rate of over 80%, significantly increasing the likelihood of a successful recovery.

Be Mindful of Key Placement

Where you keep your smart key matters. Avoid placing it in locations that are easy for thieves to access, such as entry tables or kitchen counters. Instead, store it in more concealed areas, like a drawer or away from windows, to minimize the risk of signal interception.

Stay Informed about Vehicle Security Trends

Remaining updated on the latest developments in vehicle security is important for any car owner. By following news about automotive technology and theft prevention measures, you can better protect your vehicle.

The Role of Automakers in Enhancing Security

While motorists have a pivotal role in safeguarding their vehicles, automakers must also prioritize security. This includes developing advanced software features that can identify unauthorised access attempts and improving encryption methods used in keyless entry technologies. With a focus on better designs and security upgrades, manufacturers can help protect customers from keyless theft.

Final Thoughts

Being knowledgeable about the vulnerabilities of smart keys is essential in today’s automotive landscape. With the rise of keyless car theft, it is crucial for car owners to remain vigilant. Although smart keys enhance convenience, they also introduce significant security risks. By staying informed about security news and implementing measures such as aftermarket immobilisers, installing GPS trackers and using a Faraday key safe, you can eliminate the chances of becoming a victim of keyless car theft.
