There are products out there like this already (in Skymall, most likely), but are any of them made with such care? And do they have the same strength of spring the Switchkey does?
Basically it keeps your key safe in its little box until you hit the button, at which point it presumably zips out like a switchblade. Sure, why not? They’re made by hand in Canada, you’ll have to contact them about prices and such.
