Found a key and alarm fob on Wandsworth common, Bolingbroke Grove side, yesterday. If you’ve lost it send me a message. Won’t attach image as I’m thinking is safer that way to ensure is returned to right person.
I have a suggestion for solving lost items: https://www.gearhunder.com/wallet-tracker/
This small tracker can find small items within a certain range, especially keys and wallets. If you don’t usually remember where you put the key, you can use this gadget to help you locate it quickly.
