I would have had the locks re-keyed as the guy on the phone recommended, but I just wanted to make sure that I didn’t have any of the previous issues, so I just had the technician replace the locks, And that was great as I decided after the technician was already here. Good thing he had a few different locks in the back of his van. I had him make them all work with one key anyway. So I still have fewer keys and new locks. I can’t say i am disappointed in any way at all. I don’t generally leave reviews, but i just felt like I wanted to do something good being that these guys took care of me!
