    The Acura Smart Key came apart completely when trying to remove the battery lock, unlock, truck, and hold buttons all fell out. It was difficult to try and then figure out how to get all the buttons and other parts assembled back together again. The design should really have some plastic hooks to hold the outer key button assembly and battery/electronic assembly together. Did anyone really tested this design with several end users to make sure this did not happen at all.
