Chevrolet Cruze sold in India has got Flip Key as standard key. Although these keys are made up of high quality plastic but some times due to heat or general wear & tear, the rubber buttons (Lock, Unlock and Boot) on this key breaks and comes out. There is a big hole left at that place.

You can easily repair these keys by inserting a piece of rubber in that holes and then covering them with a tape. Finally you can insert silicon cover on top to protect the remote circuit from dust and moisture. Silicone covers also protects the key from breakage in case of accidental falling of key.
