This item is no longer needed as I replaced the lock on a new post. This is a key and cylinder removed unused from a new post from the popular bobi series. Three keys are included. I removed this because I replaced the handle with a non-key type when I purchased the post. For those who have problems with their keys, or those who want to switch to a key type, how about it? bobi bobi post bobi bobipost Spare key Bonbobi POST Sekisui Design Works
