Handcuff key

I have a set of Hiatt best handcuffs marked also with warranted wrought and hard. I am a after a key to suit these cuffs. A tall order I know but I thought there may be someone making repo keys or someone may have some ideas on how to make a key. I have a few pairs of cuffs and find this sight to have a great amount of information on this subject.

thanks Meno
