If you would like to buy a group of locks of any type from this site to operate the same key simply add a suite reference.
Suiting a group of locks means that we will manufacture them to operate off the same key. This could be a benefit if you'd like one key house or all the doors on the front of the house to operate off one key and the back off one key - instead of individual keys for every door!
