Cobra Key Holders are a small plastic loop and tab that allows you to hang your keys on the Cobra Keyboard's individual locks. When an Access Key is inserted into a lock on the keyboard, the Key Holder is released allowing you to demo your vehicle. When you are ready to return your keys to the keyboard, simply push the tab up under the lock until it clicks, then remove your Access Key. When the vehicle is sold, the loop is easily cut with wire cutters to release the keys. When you need to hang a new set of keys on the lock, use a new Key Holder and insert the loop through the keyring and into the tab, then push the tab up into the lock to fasten to the key board.
