Here’s an idea for a lock in a modern-futuristic game.
A chemical lock: this lock requires you to put a specific chemical compound into. This chemical can be as simple as table salt (NaCl) or as volatile as azidoazide azide (C2N14) which explodes even when you do absolutely nothing to it.
This could lead to some funny moments where your party is completely stumped by a lock that wants “dihydrogen monoxide” but nobody realizes that the lock just wants water.
