The Nite Ize Infinikey Key Chain not only keeps your multiple keys handy, it allows you to isolate and remove any one of them without having to struggle with a stubborn split key ring. Just slide the key you need to the narrowed top. The neck of the Inifini-Key keeps your other keys from following - and unlock the simple carabiner clip to remove. The carabiner can also be used to attach the Infini-Key to a belt loop, backpack, or second key ring, keeping your keys secure and handy wherever you go.
