Everyone has been there. You begin fumbling with every key on your key ring as you attempt to unlock your door. It’s difficult to avoid, particularly if your car, house, and workplace all use the same set of keys. This can be resolved with the use of nail paint.

To mark keys, especially ones that look alike, just apply nail polish to their tops. Sort the keys according to color (blue for home, red for work, etc.). That way, you’ll always have access to the key you need. Just be careful not to leave a mess on your hands by waiting for the polish to dry.
