How it works

Your key moves in. Nothing is reprogrammed.

  1. 01

    Open your old key

    The circuit board and the blade come out whole. No soldering.

  2. 02

    Move two things

    Your circuit board and your blade go into the new housing.

  3. 03

    Close it up

    To the car it's the same key, so it unlocks and starts first time. No dealer, no locksmith.

It'll come with the tools you need and a step-by-step video for every stage.

Will it fit?

Questions

Fair questions.

Does it need programming?

No. Your own circuit board and blade move across, so to the car it's the same key. No dealer, no locksmith.

Will the remote still work?

It's designed to. The signal goes out through the leather top and the woven back, and the end your ignition reads isn't enclosed in metal. Every prototype is tested for remote range and first-time starts on a real Polo before anything ships.

How much will it be?

The price is set once the metal prototype passes its tests and the parts are quoted. Everyone who leaves their email gets 20% off at launch.

When can I get one?

Pre-orders open for the waitlist once the metal prototype passes its tests. You'll see the delivery date before you pay anything.

My key is different. Will you make one for my car?

Not yet. Comment your car on TikTok: the keys people ask for most get made next.
