If you’ve ever taken your car to go surfing, you’ll be familiar with this unique predicament that exists when you arrive at the beach — what do I do with my keys?
One solution is to put them in a dry pocket in your wet suit. This works but there’s always a chance of a big wave ripping the pocket open and sweeping your keys out to sea.
Another solution is to put them in a lock box that hangs off some part of your vehicle. This works pretty well, although the lock could be too small for your car or your fobs too large to fit inside the cavity.
I began a thought experiment about alternative ways I could solve this. Ideally I would like to just lock my key in my car and when I’m done surfing somehow be able to get back into my car.
For reference, my vehicle is a 2017 Chevrolet Cruze equipped with an RKE [Remote Keyless Entry] system where I can push a button on the door handle and get into the car that way.
Because I have a smart key, I knew I would need to put the fob in some sort of faraday cage to block the RF signal or else anyone would be able to simply break a window, push the start button, and drive away.
Inside of a faraday cage [or in my case: tinfoil] I can successfully lock the key in the car. Now how do I get back in?
