Is Using a Car App More Secure Than a Key Fob?

With the increasing use of key-fob signal interception to steal cars, many car owners are wondering if using a car app on their smartphone would provide better security compared to using a traditional key fob. The answer is both yes and no.

Relay attacks, where thieves intercept the signal from a key fob and use it to gain access to a car, have become a common method of car theft. In response to this, some car manufacturers, particularly those of electric vehicles, have developed smartphone apps that allow car owners to lock, unlock, and even start their cars remotely.

At first glance, using a car app might seem like a secure alternative to a key fob. However, it is important to consider the potential risks. Smartphones can be hacked, and if your app data is compromised, it could expose sensitive information such as passwords, PIN codes, and even the car’s VIN number.

Recent tests conducted by internet software organization Mozilla revealed that many car manufacturer apps, including Hyundai’s, performed poorly when it came to privacy and security. These apps collected excessive amounts of personal data, required users to grant permission to sell their data, and offered little control over how the data was used. None of the tested apps met Mozilla’s minimum data security standards.

While using a car app to lock and unlock your car may provide some security advantages, it’s important to be cautious about the potential risks associated with data privacy and security. It is advisable to stay updated on the latest security measures and consider additional security measures such as car alarm systems or steering wheel locks.
