Common Failure Modes
Liquid spills and physical debris are the primary killers of keyboards. Mechanical switches can develop 'chatter' (registering double keystrokes), while membrane domes lose elasticity.

Mechanical keyboards can last for decades due to durable individual switches. Membrane keyboards degrade faster as the rubber domes lose their elasticity.
