I haven't gotten the spindle out yet but the first key looks like this and they are both the same part number. Should be a standard hardware store item.

My atlas parts manual says its a special key, I tried a few different sizes and none seat right. I wonder if the two models use different keys for that. Is the spindle cut all the way through where the key seats?

This is from my 101.21200 aka Atlas 3950. Part number is 106749
The keyslot in my spindle does not go all the way through.
If you have a key that's close just file to fit.
