Maybe just use an rfid coil in the ignition and turn a key to start like immobilizers have done for like 20-30 years at this point.

Better yet use physical contacts in the key and use an on key cryptographic controller to do public key authentication.

That way key material never leaves the key itself after being manufactured making it basically impossible to steal the car without the key.

That also solves the problem of the dealership needing to continue charging hundreds of dollars to replace a lost key.

This is why they did it ya know.

Squeeze every drop out if the consumer you possibly can

New cars fucking suck.

The solution to that is open source tooling to download backup and re-upload your private key material to a set of keys.

Doesn't solve the issue of the key cut though.
