The cabinet is the easy part; the system is what makes it work. Every hook needs a fixed position, every key a matching numbered tag, and a register that says who has what. Without those a full cabinet is just a locked box of unidentified keys. Buy more hooks than you currently need, because retro-fitting a numbering scheme is far worse than leaving gaps. See key tags, key rings and key holders.
