The modern BMW keys aren't cheap! They contain sensitive electronics, breakable buttons, and wireless transmittors -- all of which can get damaged, making for a costly potential trip to the dealer for a key. This nylon webbed key protector is designed for the newer "square" keys, but can be used on any key for some extra protection. This key fob wears the authentic mark of a Genuine BMW accessory, the BMW Roundel logo, on the front, as well as the distringuished BMW motorsport ///M logo on the crease.
