I did some consulting work at a big pharma company. And they solved the whole problem of someone stealing (or more likely losing) a RSA key by keeping all the keys at the helpdesk!
You just called up, said you need the ID, and they read you the number over the phone...
Me: "Hi I'm XXX and I need the RSA key for COMPANY X."
Helpdesk: "Okay... It's on the board here somewhere... Found it... It's down to the last bar. Let me wait until it flips... Okay. Six bars... 643332."
Me: "Thanks a million."
But on the other hand, your garage door works with a rolling keY too, and you're also SOL if you lose your opener (unless you, ironically, have a keypad).
