How does it make a car door open without anyone using the car's controls to open or close, how it works with a relay attack?

Many modern cars have a keyless access system that allows you to unlock and operate your car without using a physical key. Instead، they rely on a wireless connection between your car and a small device called a key fob or car control that you carry with you. Closely، even if it is actually inside your home، the hackers can eventually unlock your car and potentially operate the car without physically touching your key. This technique forces your car's control to emit frequencies، these attacks exploit wireless communication between your key and your car and can be carried out physically without touching your car or keys.

Imagine that you are at home with your key, and your car is parked outside. Criminals with a signal amplifier can amplify the signal emitted by your key, making it appear that your key is right next to your car, even though it's inside your home. Your car, believing the key is nearby, will open the doors and may allow the engine to start when it shouldn't be running.

Two thieves work together in a relay attack. A thief with a device is standing near your car، while the other is standing near your house to unlock the car، and the signal goes to the thief near your house and he catches it. They then transmit that signal to the thief near your car, tricking your car into thinking that the key is there, so the lock will be unlocked and likely accessible.
