Master M1 Bump Key Template

[Billy Neel]

Hey guys just wanted to share this template I made. I'm sure some of you can make a bump key without a template but this template is for the rest of us guys that want to make sure they are doing everything correctly. I have made about 3 bump keys using this template and they all work properly. I hope this template helps you as it helped me. Good luck.

How to print template properly:

1.) Just print it. You don't have to resize it or anything. The proper dimensions are already set correctly. (Print ready .pdf )

After printing the template all you have to do is cut out the template and paste it to the blank key. Then cut out the key using the template as a guide. You can use a file, dremel, or lishi cutter to cut out the key.

I'm not sure whether or not this is a false positive, but according to virustotal.com one of their analyzers showed it as being a potential malware site.

Not to mention the fact that using a paper template sounds like a rather imprecise way to make a key. I don't know, maybe others have had great results, but for me, a reasonably precise digital caliper will run you like $10 at Harbor Freight, and depth/spacing info is all over the Internet.

Thanks for the heads-up abou the potential threat, btw.

Definitely a false positive. Mega is just like any other file sharing website. It all depends on the content you upload. The file is safe. Anyone can check and verify.

Templates for me is the best method and I've been making bumpkeys for a long time. This template isn't for you. Stick with your calipers.

Okay, just to clarify. The virus analyzer I used didn't have an issue with the file being hosted by Mega, but by the link itself.

I can assure you it's safe.

If you are a locksmith perhaps you will recall this was the accepted way to make Chicago K4 keys back in the day. It seems a strange way to make a key but it is an accepted technique in the trade, just not used much these days.

Learn something new every day. Lock work is a small part of what I do professionally (and I'm fairly young), so I don't know this technique first- or even secondhand.

Probably since I come from a family of machinists, I'm obsessed with precision, so I don't know that the paper template technique would work out for me. Maybe off some card stock...but I think I'll stick with a micrometer.

Ahh, ok I didn't know that either. I simply saw a post I thought a little strange by someone with no other posts and thought it might be a good idea to scan the link just in case.

Anywho, I apologize if I was incorrect.

If you know much about Chicago or Junkcunc/American double-sided wafer locks you would know that the wafers are so close together that an ordinary code machine is almost useless, the cuts are blended together. Thus a file and a template was commonly used or tryout keys.

Great patent drawing, Cledry.

Some patent drawings are especially cool.

Reinventing the wheel. Why not just go and make an original key, all 7's? Just take and blank, set up the Framon or HpC and go for it. You end up with a perfectly centered set of cuts. Don't forget to make the extra cut on the tip of the key. This is one big thing I have found in purchased keys. The tip is not cut "on center" and thus the first pin does not "jump" on the center with the rest.

To make the last cut over the card or spacing block set, just count the turns and make one more cut like the last one. Master is .125 between cuts, so it should be about 2 and 1/2 turns after the last cut. OR SO.

My 2 cents worth.
