Keyless Systems: Even New Cars Are Still Easy to Hack

Keyless systems, known as “keyless entry,” have brought drivers unprecedented convenience in everyday vehicle use. Simply keep the key in your pocket, and the car unlocks itself. The engine starts effortlessly with the push of a button. However, what is convenient for drivers has become an opportunity for thieves. Tests by the renowned German automobile club ADAC repeatedly show that even the most modern cars remain an easy target for thieves using signal extenders. Why are keyless systems so vulnerable? How can thieves steal a car in mere seconds? In this article, you’ll learn how signal extenders work, what the biggest weaknesses of modern cars are, and what you can do to better protect your vehicle.

How Do Signal Extenders Work?

Signal extenders, used in so-called relay attacks, can amplify the radio signal between the key and the vehicle over tens of meters. This allows thieves to steal a car while the owner is sitting in a café or relaxing at home. According to ADAC, thieves do not need sophisticated equipment. A signal extender device costs only a few dozen euros and requires minimal effort to use. The theft process takes just a few seconds, and the vehicle remains fully operational until the engine is turned off.

Alarming Results of ADAC Tests

ADAC tests revealed that of more than 700 vehicles tested since 2016, only about 10% were able to withstand relay attacks. In 2024, ADAC tested 65 models, of which 54 could be illegally unlocked and 49 even started. The only exceptions were vehicles equipped with advanced technologies such as Ultra-Wideband (UWB). This technology accurately measures the distance between the key and the car, making signal extension impossible.

Why Are Motion Sensors in Keys Not Enough?

Some manufacturers attempt to increase security by using motion sensors in keys. These sensors deactivate the signal if the key hasn’t moved for a certain period. However, according to ADAC, this protection is only partial. Before the key deactivates (usually after 5 to 30 minutes), thieves have plenty of time to carry out the theft. Additionally, if the key is in the owner’s pocket and they are moving, the signal remains active.

How to Protect Your Vehicle?

The ADAC test results clearly demonstrate that current keyless systems remain vulnerable, and car manufacturers continue to overlook the risks. Despite advancements in technology, the majority of vehicles are still easily hackable. Therefore, it is crucial for car owners to take steps to protect their property.

One effective solution against keyless thefts is the Pandora Alarm security system. This system uses advanced technologies to protect vehicles, including remote control and monitoring through a mobile app. Pandora Alarm can effectively safeguard your car not only against relay attacks but also against other types of theft, such as towing or misuse of remote start.
