If you are the owner of wild keys which are trying to escape all the time, you may need this: a belt clip made of stainless steel. This should help to domesticate the beastly keys and to hold them on your side.
Note: It is even more useful now since I added a bottle opener to it. As a german and particulary bavarian, I have to open a lot of beers!
The belt clip comes without keychain or beer!
If you don't have a keychain already, I can recommend this one from Amazon
