All right, here, instead of using those keys, you should take this extremely convoluted and foreign-looking mobile phone, into which you have to insert all of your keys, type in a special password, and then oh, well, it works on most locks but not all of them, so you’ll only be able to replace some of your keys with it, so now you should carry this new weird mobile phone on your keyring too. Also, it doesn’t work as a phone.
