Two steps on your way upstairs, and the handoff is done. Here is exactly what it looks like.
Every membership ships with a Faraday pouch. Slide the fob in, press the flap shut, and it stops transmitting. It can't be picked up, relayed, or used to open or start the car while it's in there.
There's no prescribed spot. Pick whatever is most convenient for you.
Tucked between the spokes.
Quicker to attach on your way out. Every lockbox ships with felt pads you can place anywhere on the box, so it never sits hard against your paint.
Your keys stay in your lockbox until it is your turn for your car to be washed. Once your service is complete, the keys go right back in, and the lockbox goes right back where you left it.
