Here are some keys you don’t want to lose on the dance floor. For those lucky enough to afford the new BMW i8, they’ll definitely want to match it with this BMW i8 Key Fob. Of course, the high-resolution screen locks and unlocks doors, yada yada. It’ll also display the range left on the existing charge, when to recharge and likely, other dashboard-type stats. Even better, the unit also features user-programmable functions. It does cost $1,000, so it’s not a drop in the bucket. Someone paying $135k for the i8 though, probably won’t worry too much about another thousand.
