> Adding in a stick of metal that can be trivially bypassed does nothing to make the car more secure. Everyone can use a flipper zero to unlock a car. Not everyone can hotwire a car. Keyless ignition means criminals have a vastly larger recruitment pool of people they can offer money to do something stupid (like stealing a car for them).

> Everyone can use a flipper zero to unlock a car. Not everyone can hotwire a car. You live in a tech bubble if you really think this is the case. Attacking a lock cylinder is a lot lower-skill of an attack than a cryptographic attack. Recent car theft epidemics have shown this, e.g. #kiaboys

  > You live in a tech bubble if you really think this is the case Everyone can operate a flipper zero with a custom firmware which provides a three step process: * Select car make. * Press button A to unlock doors. * Press button B to start car. > Attacking a lock cylinder is a lot lower-skill All "recent" cars (as in everything from about 2000 and up) have an immobiliser. It's even mandatory in some countries since about 2000 [1]. Meaning the key "talks" to the car when you turn it in the lock cylinder. Locking picking the lock or hot-wiring the car isn't going to start the car. And that's not even taking into account the car alarm will go off if you just lock pick a lock on it.

    In the grand scheme of things, very few people have flipper zeros. Few even know what they are. Meanwhile, I think a pretty high percentage of households have a screwdriver. > All "recent" cars (as in everything from about 2000 and up) have an immobiliser You mean some kind of wireless communication protocol that can be hacked with some kind of handheld SDR device? Why is a keyless entry trivially bypassed but an immobilizer transponder, gee, that's just impossible to hack. Everyone can operate a flipper zero with a cusom firmware which could bypass a transponder. So then all you need is the flipper zero and a screwdriver. Wow such better security for the hassle of having to actually stick the key in the hole every time. I'll still take the keyless option. If someone really wants in my car, they're getting in. If they really want to steal it, they'll steal it. Requiring the thief to have an RF hacking tool and a screwdriver just isn't that much higher security in the end IMO.
