Glad to hear it worked for you! I keep a couple of spares around myself. I keep one on my key chain as well ( just so I always have a '3D' example to show off! ). It's sometimes easier to show it than it is to explain it.

First successful Key I've made was with this!

It was a Schlage lock, I measured my key with calipers, and figured out the code. After plugging them in, I downloaded the file, and mirrored the model. I had to also adjust the slot angles in one of my preferred editors (I couldn't figure out how it worked in customizer); Printed it. Bingo! worked perfectly.

Now, I can print one for my son to use, and won't be so concerned if he loses or misplaces it. Perfect for making spare keys for my wallet too.

I think this is pretty neat, but it's making me a bit paranoid for the people using the customizer. I know that in practice someone's not going to go through these 56 remixes, track people down, 3d print their key, and break into their house, but it's kind of off-putting in a pleaserobme.com kind of way.

Maybe thingiverse should have a way to have customizations default to private?

Instructions

Warning! - this is for printing a PLASTIC key. This key is optimized for printing at 0.30mm layers, and is only 7 layers thick!!! Although it works fine - it is plastic - and can / will break off if you are not careful! With that in mind, you simply need to enter in an appropriate code for your key, and select the style of key you want to print. You may want to have a nail file on hand, to remove any extra bits of plastic first. Leave the code number blank, to generate a random key. I would love to see copies that anyone prints - however - BEWARE - you might not want to post a working copy of your house key - someone else might print one too!

If you hold the key in your left hand, with the blade pointing to the right, the KeyCutCode reads from left to right. 0 for no cut up to 9 for a maximum cut. You can switch to the 'top' view in 'customizer', and hold your key in front of the screen while you adjust the values. It may take a couple of prints to find just the right match, fortunately it doesn't take long to print, and doesn't use up a whole lot of your filament. You might want to print your first try using the 'straight' key header, to save even more time / filament!

Tried it with a Kwikset lock but no luck. The key could not be inserted in the lock due to the grooves being slightly too narrow I think.

You can determine the key cut code by measuring the depth of each of the cuts on
an existing key. The Kwikset Classic key which is the most common in the US, has
5 cuts that you will need to measure. Start on the left side of the key. Take the measurement of the depth of the first cut using calipers. The measurement you just took correseponds to the 1st number of the code. You do the remaining 4 cuts the same.You can use the following chart to find the code for your key, you are only concerned with the "depth" part of the chart.

It's pretty much a guessing game for now. If you hold the key in your left hand, with the blade pointing to the right, the KeyCutCode reads from left to right. 0 for no cut up to 9 for a maximum cut. You can switch to the 'top' view in 'customizer', and hold your key in front of the screen while you adjust the values.

How do you determine your key's "KeyCutCode?"

mb20music on Feb 23, 2013 said:

You measure the depth of each of the 5 cuts (for Kwikset keys) with a caliper, this will give you the cut code of an existing key. Going from left to right.

Oops, didn't use 'reply' - see the new post above!

Why is there a "B":on the back of the key?

Belfry on Feb 22, 2013 said:

Think of it as a form of advertising / branding. It's the Belfry 'B'.

I made a couple of changes, to remove some items showing up in 'customizer'. I think it's in good shape now.
