19 Keys is a British game show that aired on Five in late 2003. Across 20 episodes broadcast on weeknights from 10 November to 5 December, contestants competed in a quiz format where correct answers unlocked numbered keys leading to prizes. The show combined general knowledge questions with a strategic element of choosing which key might open the next reward.
