The simple design of our INFINI-KEY 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 INFINI-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.
