What Is Tesla Passive Entry?

This article explains how Tesla's passive entry feature is vulnerable to thieves who use relay attacks.

Tesla's system offers car owners passive entry by using a mobile phone key fob instead of a traditional key fob.

It offers the Tesla Mobile App which can be used to locate car owners and open the vehicle without touching a key.

However, thieves are able to use relay attacks to fool the entry system and gain access to the vehicle.

Other brands of vehicles are also vulnerable to these types of attacks, but they do not offer passive entry like Teslas system does.

Model 3 owners should expect this vulnerability in their cars, as thieves can redirect communications between their phones and vehicles in order to fool the entry system.

The decision to purchase the 2023 Genesis GV70 will ultimately depend on your specific circumstances and preferences.
