Harmed Key Shells: Plastic cases typically break or the rubber buttons wear away, exposing the delicate internal circuitry to moisture and dirt.
Circuit Board Failure: Dropping a key or exposing it to water can harm the internal components, leading to a failure in the remote locking or transponder signal.
Battery Connection Issues: Sometimes, a “dead key” isn't due to a dead battery, but rather the battery terminals inside the fob breaking away from the circuit board.
