Sure thing. First rule: keep the lock simple enough that only a proper key or code works, but make the pins or tumblers double‑check themselves. Use a split‑pin design—if one side misaligns it’ll jam. Then add a secondary cam that locks out when the lock’s closed but slides out when you give it the right torque. In practice, give yourself a small, hidden lever in the case that lets you twist the cam out without the key. Test it against a screwdriver, a lock‑pick set, and a bolt cutter. If it still resists, you’re good. If it opens with a simple tool, tighten the spring tension or change the pin geometry. Keep it tight, but give yourself a fail‑safe that only you know how to trigger.
