Get this from Etsy. Great for emergencies. Anyone asks? Emergancy moneyfund maybe? So if I have an accident, become Ill, maybe get swelling or it became painful etc. I'm safe in the knowledge I can remove when away from the KH at work etc. As the locks numbered and the KH has a photo of it. I coukdnt cheat.
My spare key is on a thin gold choker necklace fastened and crazy glued shut around my neck. It's frustrating to have the key that close, and the only way to get it off is to break the chain (in an emergency).
