I have previously purchased a Kensington combo lock for my Latitude 5501 and it did not fit. It was also listed as compatible so I tried it out and it fits the hole and locks. This is a one key lock, not a combination, so be careful where you put the key. One thing that impressed me is how small the lock head is. I'm used to big, awkward things dangling from the side of my laptop, but that's not the case here.
