Thanks.

I cleaned up the key blade and noted where the plastic head stopped on the blade so I wouldn't allow any putty past that point making the blade too short to fit in the tumbler.

I mixed a small amount of the putty and rolled it out like dough until it was half the thickness of the plastic head. Then I placed the blade on the putty, folded it over and pressed it in. I folded the remaining putty over two more times and shaped the face with a razor blade as the putty started to harden.

I used snips to cut a traced outline and then sanded it as it cured. I used a dremel to grind the hole. Once the putty is completely cured, it's like a rock, so I did all the shaping while it was still kind of rubbery.

I also rested the key blade on 2 utility knife razor blades to allow the blade to be aligned with the thickness of the putty as it cured. I didn't want the key head to cure crooked.
