SenautoQuicksand Key Fob Cover Case Keychain for Mini Cooper F54 F55 F56 F60 F57 2014-UP (Pink)

Why are people worried about their keys scratching?? Never thought about it...had my car for 7 years and there's not a scratch on the key fob.

Does this fit older model key fobs?

Does it have to be taken out to start the car?

Is it a hologram? Or is there glitter inside?
