In lots of "flip key" styles, the hinge system is a point of failure. The metal blade can snap off the fob, leaving the owner without any way to turn the ignition.
5. De-programming
On rare events, a key might lose its "sync" with the automobile's computer system. This typically requires expert diagnostic devices to re-link the transponder to the Engine Control Unit (ECU).
