It’s recommended to have at least two anyway, to still have access to your accounts in case one is lost. That means you can keep one key at your desktop and you’d only need to go up to get your keys when adding them to an account.

Having two in the same house is a pretty bad compromise. Ideally you'll want one of them to be physically somewhat distant (in case of a fire etc.), which makes things even less ergonomic.
