There cannot be a piece of technology in everyday use that is cruder than the door key. Locks and keys were common in Assyria thousands of years ago. Later, wealthy Romans would keep valuables in locked boxes and wear the keys as rings to ensure they were always handy – and to remind others that they were rich and important enough to own stuff worth securing.
The practice of wearing keys – albeit of a rather updated kind – for convenience and not a little status symbolism is now being revived. Senturion is a universal, wrist-worn key that can unlock or activate an almost unlimited number of devices, from car, house and office locks to show-off gadgets such as electronic swimming-pool covers and gun safes. It takes advantage of digital-locking technology familiar to owners of cars that open and start with the wave of a fob, and of Yale and Paxton digital door locks. Except that one strikingly macho Senturion bracelet can be programmed to open them all – although ideally not at the same time.
A touch of luxury genius was to create the more costly version out of exquisitely cut and polished meteorite, derived from a shower that hit Namibia 100m years ago, after streaking through space for some 4bn years. There’s no reason Senturion should be made of an asteroid and the material has no great intrinsic value. It’s just intensely rare and evocative.
