Universal Door & Lock System is a complete, modular solution for building interactive doors in Unity. It supports three door types—animated, physics‑grab, and push doors—plus four lock types: key, keypad, dial (safe), and lockpick. The system includes a player interaction raycast, inventory and pickups, UI prompts, and fully working UI minigames for keypad, dial, and lockpicking. Everything is configurable from the Inspector and designed to be easily extended with new lock or door behaviors.
