I would like to see a means to lock and immobilize the vehicle, while leaving the vehicle key inside.
A great way to do this would be to have an NFC enabled passive key, say on a rugged, waterproof (100m) watch-like wristband, which is used to lock the vehicle, immobilize it, and temporarily deactivate the vehicle key such that if someone breaks in and gets hold of the actual key, than can't steal the vehicle.
I would use this when out hiking/backpacking/biking/kayaking/etc. - I don't want to take the chance that I'll lose the actual key, so I want to be able to keep it on my body.
I don't want this to be something rechargeable - it should be totally passive. It should be able to survive smacking on rocks, being frozen, getting soaked, etc.
On my Land Rover, this works by first closing all of the doors and windows, and then holding the key up to a particular point on the vehicle within a certain time limit. The vehicle then locks and arms the security system. To open the vehicle, I first press the trunk button, and within a certain time limit, I hold the wristband up to the same point on the vehicle, and it unlocks and disarms the security system.
