One day the inevitable happened, I reached for my keys and the ring with the remote was gone. Staving off the panic, I assured myself that it would turn up. Luckily, the lawn service at my apartment came across it a couple days later... after they ran it over with a riding lawnmower.
Staring at the mangled corpse of my absurdly costly key fob, I resolved to solve my key loss problem once and for all. With the simple hack I describe here, I haven't lost a key since! (Though I have yet to replace the remote.)
This project was made proudly at the i3 Detroit hackerspace.
