      But does it work with the foil? We found lots of metal containers didn’t block the signal. Hell even a pouch advertised to do it still worked.

      Thick metal containers with over lapping lids worked best.

        I tested with bolt EV, 2019?, model, because while the keys are in my house they would still allow kryless start to my car in the driveway. 2 layers of crumpled aluminum foil worked to fix it from ~15 feet away

    This is actually really helpful it makes your keys be wrapped in aluminum foil and that’s pretty helpful because it makes your keys be wrapped in aluminum foil

      I was really skeptical about this, but after a few weeks I realized my keys were wrapped in aluminum foil and I actually started feeling safer

    At least this one is fake. Not like the Flock Camera one where it turned out that they actually each have about 2.4lbs of copper and 0.28oz of gold.

    Isn’t there a thing where car thiefs use an RF booster to make newer cars think the keyfob is right next to the receiver?

    Personally, I’d want an antenna on/off switch that gets activated by shoving it in the keyfob hole. Seems reasonably secure.

        Heh, it’s on the right track. But as an IT guy and tech nerd, I’d want to go for something like this. I’ve even set mine up for computer logins back when I had an Active Directory test environment for learning.

        Nono, you see that would actually be user serviceable and convenient for the consumer!! You’re fired Smith. Johnson, tell me again about your llm powered brain mounted key fob with ad injection and $20 a month subscription? I love it! You’re promoted!!

      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.

          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.

      Oh god I always hated those cars that start by pressing a button. Fuck off let me turn my key. I like the thing where the car unlocks automatically if you are next to it and all that but for the love of god the press button to start car thing needs to die.
