Monkeys are fun to look at. Now they can help you decipher one key from another. The Fred Monkeys key caps come in several colors so that you can easily determine which key is for what door or lock. You can also give a key to your children so that they have a way into the house in the event that you are not home. It is also fun for them to have the colored key caps for bicycle locks and school locker padlocks. The six designs give you the option of making up to six keys look different. The hardest thing about these is remembering what monkey face and color you put on what key. Labeling the back of the key cap with permanent marker is a good idea as well.
