Making my first keys with the X6 (Silca LF37)

Let’s try to make my first key, from what we know.
Silca LF37 – Lock Focus – S0001-S1000 Series AND T0001-T1000 Series
This is a followup to Reversing the X6 Key Cutting Machine

And we will guess the missing gaps!

First up, here’s the profile

The start, !SB0 was the start of the 2 most similar keys I seen, so we will run with that.
Same with the following 0,2
Then 700 for the key width.


Then I will use 229,0,0,280 again, due to being most similar.


Now, the key itself!


So now we have


Now the depths, the 0’s, and so on!


For a final file of

Let’s see if it works!

See the youtube video here to see the testing!

As it turns out, this needed a minor tweak, also, in the original test, I actually duplicated the cut depth, also seen in the video.

This is the final working, and successful file.

For those that don’t want to watch the YouTube video.

There were more dramas in paradise.
As you can see in the below picture, the key does not fit into the jaws properly.
The key is too short, and the ‘handle’ gets clamped.
This made aligning very hard.

I had 2 successes, but due to the imperfect alignment, my third key failed.
That was not going to happen again, so I quickly drew up an alignment block on OnShape, and printed it out.  It was 0.1mm too wide, and 0.2mm too thick.
I simply sanded it a bit to make it perfect, as pictured below.

That block, in hind sight, should have been longer than the clamps, to make it easier to grab, otherwise, works perfect.
The youtube video demonstrates it’s usage.

Grab it from onshore here!
I have made the above fixes to the file.

After using the guide, I was able to cut the remaining 40 or so keys with no failures at all!
