I have several padlocked sheds on my property. To keep track of which key goes with which lock, I bought two identical sets of key ID rings, the kind that stretch around the edge of the key head.
I put a ring on the key and the matching ring on the padlock that goes with it. Now I don’t have to test all of my keys in each padlock before finding the one that fits! — Michal Jacot
