This article shows how relaTesla Passive Entry: What Is It
y attacks by thieves can compromise Tesla's passive entry system.
With Tesla's approach, passive entry is possible without the use of a standard key fob by using a cell phone as a key fob.
It provides access to the Tesla Mobile App, which allows users to identify their car's owners and start their car without using a key.
However, relay assaults can be used by thieves to trick the entry system and enter the car.
While other automakers' models are equally susceptible to these attacks, their systems do not provide passive access like Tesla's does.
Owners of Model 3 automobiles should be aware of this issue since thieves can trick the entry system by rerouting connections between their phones and vehicles.
By needing the key fob to be close by in order to unlock the car, Tesla's Passive Entry system defends against Bluetooth relay attacks.
The key fob sends out a low energy signal that is challenging to imitate and is outside the Bluetooth signal range for the majority of devices.
Therefore, the conventional lock-and-key method is no longer necessary due to this technology.
Additionally, it makes it possible for drivers to control their vehicles without a physical key or an app key fob.
