I received these pictures from my best friend"Bender" He told me that it is hardly for him to believed how the key case important it is for your Car key. Yesterday,he felt so excited that the key case saved his key fob.I asked what was happening? He told me that when he was out of the office and suddenly his Model X car key dropped out of his pocket in the car ran it right over! Fortunately，it saved the key case by the protector shell. Now the car key fob still works!! Want to share with the other Tesla owners. If you also have amazing experience with your key fob,you also can share below.
