Security of keyless entry

I watched "Crash and Burn" movie (really bad, not recommended) on Netflix a couple days ago. It is about car thieves. They use IPhone-sized handheld wireless device to unlock and start any newer car that had keyless entry in a matter of seconds.

Does such technology actually exist?

Re: Security of keyless entry

Does it exist? Technically, yes, but you won't be doing it with an iPhone.

What you will need is something that will transmit in the freq range of the RKE system (not done by a stock iPhone), you'll need to know the format of the security codes, and you'll also need to either get lucky or have plenty of time so you can get the right code transmitted.

If you have that kind of time and money to waste on pulling this off just to accomplish stealing a mass produced vehicle, you're more likely to either just buy one yourself or just beat the owner with a pipe until you retrieve one of the real keys.

No reason to get all Hollywood Hacker fancy about it.

It doesn't call the car itself. It calls a module installed in the vehicle.

As manufacturers expand the vehicle management capabilities to smartphone applications (as some new vehicles have the ability to be managed via the phone), this will become possible, but will still require cracking the authorization codes or the owner's password. Regarding our Grand Cherokees, though, the only thing you can do with a phone is connect to the audio system via Bluetooth. You can't start it without doing some serious hacking. Considering how easy it is to carjack, you're better off just liberating the key from the owner.

There's an app for that.

Re: Security of keyless entry

I'm sure each vehicle uses a unique security encryption key so this sort of thing is probably not possible. Anyone read any articles about this? I'm sure researchers have tried it.
