Query: READ CAREFULLY

This is only the key NOT the lock!!! This can not be used as a stand alone product. In order to use the key you must already have purchased the locks. Make a sure you read carefully. I found the descriptions confusing!!I gave this particular product two stars, because the key and key holder set is unnecessary. I suggest buying the starter set, to determine if the locks work for you and then you can order more locks. This lock key and holder is only if you want an extra key.On a side note, I did go back and order the locks (the package of four, which doesn't come with a key) and I love the concept! It works wonderfully, was easy to install and required no drilling! My husband was also very impressed.
