2018-01-22 Key Fob Sleeve
Twice I’ve gotten back to my car to find the windows open. Other BMW i3 owners have reported seeing this happen as well. It happens when I accidentally press and hold the unlock button on the remote while the fob is in my pocket with other things.
Some people recommend buying a $20 cover for the fob, but it’s more fun to design my own and print it in TPU.
The car generally unlocks when I touch it with the key fob nearby in my pocket, so I don’t often need to press the buttons. If I do need to press the buttons, I can pop it right out of the cover, since the TPU is flexible.
