Chastity device discussions and reviews discussion

Ok so maybe I have overlooked or just down right missed it but have not been able to find a thread discussing this so if hear goes. My girlfriend and I have been thinking about getting a more secure lock for my device ( cheap brass lock on it now not secure at all ) at first I was thinking about getting an abus lock but after talking and deciding that we might want to put the key on a necklace we decided that if possible we would like to find an antique style pad lock with an ornate skeleton key or at least a decorative lock and a decorative key. After searching Google I wasn’t able to find much. So I’m wondering if anyone here knows where we could find something like this we have looked at list locks but they seem to easy to pick any advice or info would be greatly appreciated thanks in advance
