Well that’s why i don’t like keyless vehicles, it’s easy to stole it with some wireless signal emulator
Im the end the principle is same like wireless garage door opener, some thieves can hijack it very easily like no effort

Do you not know what rolling codes are?

Isn’t that what the Flipper Zero is for ;-) Kia notwithstanding it’s not that easy. But the relay attacks have been around since at least 2018 and I suspect years longer.

For garage doors… Yeah, it’s been a thing

Because you can sit something there, monitor the rolling codes, then inject so it has a real one.

For a car, you have to follow them around while they lock/unlock repeatedly. And that’s only if people are using the button and not proximity. If they’re just using proximity, you’re going to have to be standing right next to them.

I think most of the wireless attacks aren't trying to be so sophisticated. They target cars parked at home and use a relay attack that uses a repeater antenna to rebroadcast the signal from the car to the fob inside and vice versa, tricking the car into thinking the fob is nearby. Canada has seen a large spike in this kind of attack. Faraday pouches that you put the fob inside of at home mitigates the attack.

So does not leaving your keys by the front door… not that I follow my own advice :-)
