My name is Ray, I own a Hardware store in fort Vermilion Alberta, I took a correspondence course on locksmithing about 20 years ago and do rekeying for my customer and occasionally picking open for lost keys etc,.
I have lost my training books and I now have a local customer who wants to master key about 30 houses , I have pins but have forgotten the principal of setting up a master system.
Would someone help me with a basic explanation or give me some education, I would be happy to compensate someone for a bit of help.
Thanks
Ray Toews
