Problem getting by a deep cut

[jeep_thing]

Hi all- So I started with a Sparrows 4 piece pick set and their cutaway cylinder. I had no problem picking it and also not to much trouble opening my own Schlage residential door on first try.

But here's the thing- I can't pick the cutaway cylinder without looking at it, and I believe I know why. The 4th cut is deep, I don't have my gauge handy but I am guessing it is a 6. In trying to set pin 5 I accidentally set pin 4 too high, attempting to get by it without looking.

I am using the shallow hook that came in my set, would the configuration of this key require a longer hook?

Thanks in advance!

I'd say that's what deforest diamonds are for.

If you can pick it using the short hook when looking, you should definitely be able to do the same without looking - it's not like the geometry changes when you have eyes on it.

Maybe try picking without looking, trying to visualize what is going on, and every one and a while check if the picture in your head was correct - and restart when it was wrong?

You can compare the depth of the hook to the key and you'll know for certain whether it's deep enough or not.
