Just put a note in the keying / comments box as you check out.
Please Note that in most cases, locks will need to be the same brand to be able to be keyed alike. There are several common key cylinder types, but each are unique and not all manufacturers use the same type of cylinder.
If you are ordering multiple keyed locks and need them all to use the same key, just enter a note in the comments box as you check out. Standard keying of under 10 total locks is free. If you have more than 10 locks or have a large commercial project that requires master keying, please contact us for a quote.
