Keyless ignition systems seem to use a car to keyfob radio signal handshake so the keyfob inside your house can be remotely hacked from the outside!

I assume from the article that when given any code your car responds with a code return. This is captured and re-transmitted with a high enough signal for the keyfob to return a valid onetime code which is captured and when in range used to open your car. I can't see how this system in these circumstances can ever be secure.

The ever-present tradeoff between convenience and security. Having to press a button on the fob was just too hard, so now you have to keep it in a lead-lined safe for it to be secure.

Pretty much all remote locking fobs were hacked years ago. Including rolling code type. Pre 2014 VAGs are especially trivial, much to annoyance of my smug looking Audi mates, who get REALLY pissed when you keep unlocking their cars

They're just bloody keys! A traditional mechanical lock can be defeated by several mechanical means and some practice; we just accept that.


Why is it such a shock that electronic locks can be defeated with some electronic kit?


And I don't buy into the now anyone can buy the gear to do it argument either, because lockpicks are hardly expensive/difficult to improvise.

Indeed. When you have a tiny 8 bit uP on the remote, it's a bit of a struggle to implement something that can't be cracked in seconds by an ordinary laptop, assuming you even have to go that far. Witness the whole IoT security debacle.
