First of all, make sure you have a fully working spare car key, especially modern ones with a chip. If you only have one key, get another one now - like today, don't put it off any longer.
A friend at work lost his car key. He only walked a short distance from the car park to the workshop, he noticed it was gone about an hour later. We all searched high and low for ages but it was nowhere to be found. We came to the conclusion that a member of the public picked it up in the car park and took it. Luckily, he had a spare at home and someone took him to collect it, an hours round trip but thank goodness he had a spare.
Some years ago I lost my wallet. Like many others, I used to keep it in my back pocket which is daft when you think about it. Getting cards stopped, driving licence replaced and losing money is a major inconvenience.
I replaced the wallet with a Pacsafe wallet which has a chain and kept it in a front pocket, the ring attaches to the wallet and the clip to a belt buckle though and didn't seem all that secure so I bought a Victorinox Multiclip to replace the Pacsafe chain. Victorinox is a top brand and like their knives it is well constructed, very secure and clips over the belt, it also has a seperate chain for keys.
