This unusual key fob design from Joongho Choi and Hyunsoo Choi for Cross Electronics is a delightful departure from our usual keychain locking/unlocking devices. It’s called “Pebble,” and it might help all of those poor souls who manage to constantly lock and unlock their cars via their pocketed fobs.
The design is relatively simple: the pebble-shaped device is comprised of two connected sliding pieces. When the top piece is slid one way or the other, the car receives a signal to lock or unlock the doors or open the trunk.
Of course, if you want the car to remain unlocked and you slip the Pebble into your pocket, you might still be faced with unintentional locking. It’s easy to see how this could happen when the “unlock” position involves the top piece being pushed out further than the bottom piece. But regardless, this slick and modern gadget might be the most attractive method there is for keeping thieves out of your car.
