Copy your own keys by using the customizer and holding your key up to the computer or mobile screen to check.


  1. Select the type of key you have (Look for code on key. Currently only 4 models available).
  2. Select the grip style.
  3. Set the heights for each notch so that it matches your key.
  4. Check your copied key by holding your real key up to the screen.

This works particularly well on mobile devices where you can pinch zoom the screen because you can check the key fairly accurately - An electronic copy in minutes from your mobile!

I got this to work, but it isn't very user friendly, and I probably would've given up if I wasn't really desperate to find a key maker with a commercial license.

For the Schlage setting the key fits perfectly but the notches are too far apart. From the first notch to the last there is at least 3 mm separation compared to the real key.

lovely, would have made a customisable key if you hadn't already!

does kwikset only have 5? as the 6th doesn't change anything?

I have not tested the kwikset key as I don't have one of those locks. I may have gotten the number of notches wrong, but I can easily adjust that if you confirm that 6 notches are required.

I have no idea if it does have 5 or 6, was just wondering.

I am thinking about deriving a new customiser for UK locks (Yale). One thing I have noticed, is 4 out of 4 UK house keys I have looked at are Yale derived (same key notch pattern) but have the pin notches slightly displaced, so There would need to be a slider for the key-stop placement.

notch height6 for the kwickset doesnt work :(

I thought there were only 5 for some reason.. Let me know if I am wrong and I'll re-enable the 6th. As I don't have a kwikset lock I haven't tested it either so it'd be good if someone could print and test for me. :)

kwickset makes a 5 pin and 6 pin key. I'd be glad to test!

For some reason I can't get the notch depth to go deep enough on the Kwikset version. I was able to print an alternative design that worked in my door but it was a little tight i was hoping your might be a little looser.

I have adjusted the notch height to go deeper just for you. :) I have also added some text and reworked the source.

Excellent I'll give it another shot!

I wondered if anyone would want it to be laid flat for printing so I have now added an option to do that. I also increased the text size and groove width on the back, as you suggested, as well as shifting the notches back a bit to match your picture for the Kwikset key. Hope that helps. Let me know how it prints. :)

Ok, I've printed another copy of the Kwikset version and posted a bunch of photos with what I've found here: http://imgur.com/a/Q4Nbphttp://imgur.com/a/Q4Nbp

Thanks a lot for your help. The pics really helped and I have made the changes. Thanks again. :)

The latest key is pretty much spot on. The text, however, still doesn't show up. There's a few more letters this time. I'll post a photo shortly.

Thanks mate! I've made the text bigger again and also added some guitar grips heads. :-) Was just wondering what printer you were using? I don't have one yet and it's not easy to see example prints around these parts.

I have a Thing-O-Matic MK7 and have been printing the keys at .20mm layer height. Nice to see some more custom grip heads too.

Thanks.. I'll see what I can do and hopefully update it in the next couple of days. It'd be good to hear about other popular key models too. :)

I think Master Lock keys would be cool. It may be possible to determine if the code on the bottom of the lock correlates to the height of the pins in the lock. In theory a replacement key could be made when the origional was lost.

Thanks for the suggestion. I'll look into it.

Isn't the key breaking off inside the lock a bit of a problem?

When in doubt, there's always http://www.shapeways.comwww.shapeways.com and get it printed out of metal or there's always lost wax casting. I've heard stories of people being able to print PLA parts and use the lost wax casting process to burn away the PLA. However, I think it might be a little hard with something this small. I guess we won't know till someone brave out there gives this a shot.

I can see that it would be, but I probably wouldn't use a plastic printed key on a sticky lock or apply too much force.

Cool!!!! Now I have a reason to become familiar with scad!

Neat! You know you can set the default preview rotation so that the key shows on a direct side view? That might help visualize it. See: http://customizer.makerbot.com/docs#rotationhttp://customizer.makerbot.com...

Cheers for that! Much easier to compare keys now.

Is it possible that the key is mirrored? I've got some pretty standard schlage keys and all of the key modes have the groove/relief on the opposite side.

Thanks for the feedback. I fixed that up now. :)
