These car keys are so ridiculously high-tech you won't even recognize them (TSLA)

BMW

Car keys are an important symbol of car ownership and freedom. 

Some companies stick to basics with switchblade-style key fobs, but some others truly go all out. 

These eight keys are like none other.

BMW's futuristic-looking intelligent key fob can do quite a bit more than open doors.

The fob uses a 2.2" touchscreen to show you whether the car doors are locked or unlocked, vehicle service information, pre-conditioning a/c settings, as well as electric drive range information. 

Pretty handy. 

The Jaguar F-Pace Activity Key is the key to have if you hate using keys.

With the F-Pace's Activity Key, by holding your wrist up to the Jaguar badge on the rear of the car, you can lock or unlock the vehicle. And it's waterproof! 

The Activity Key is available as a $400 option. 

Volvo no-key car keys.

If you're lucky enough to be visiting Sweden's Gothenburg Airport and you're renting a car from Volvo's Sunfleet car sharing program, you might be given a completely keyless car.

This new technology pairs cars and phones using Bluetooth technology and a uniquely designed smartphone app.

At the moment, the program is just in testing, but it could be implemented more widely in 2017.
