All you need to do is select how many locks you would like keyed alike and the quantity via the drop-down on the product page.
For other our other suppliers, we do not currently offer any keyed-alike services at this stage. If you want one key to operate numerous locks, we suggest that you reach out to your local locksmith, who will be able to do this for you once your locks have arrived.
