It clearly states in the description at the top of the page: "Includes lock bracket, lock and keys for security".  Guess what -- NO, IT DOESN'T.  After the package arrived, and I saw it wasn't as advertised, I went back to look at the item's page again.  There, it says the lock is optional.  I may be partially to blame for expecting an included lock.  Had I read the whole page, I would have seen it wasn't included.  However, when it's stated at the top of the page highlighting the product's features, well...you just assume you're going to get what's advertised.
