I’ve got mixed feelings about Master Lock’s dialSpeed electronic combination padlock: it looks awesome, but I have fond memories of securing my old locker with one of the old-fashioned Master Locks, you know the ones with a key hole in the back that teachers could open with a master key? Come to think of it that whole aspect of them kinda sucked. Anyway, dialSpeed strips off the clunky dial and replaces it with a fancy touchscreen. In place of numbers, it is unlocked by a series of swipes. On top of your regular combination it also supports up to three guest combinations

If you are worried about forgetting the combination, you needn’t be – Master Lock has an Internet-based combination vault to handle that responsibility for you. Of course, it being electronic means that it needs a battery. The lock runs off a CR 2032 battery, which is good for around 5 years. When the battery starts to die an indicator lets you know that you need to change it.
