can't pour the hot metal into the key mold

I have the tin with the clay and the key's impression but I can't pour the hot metal into the mold... Any suggestions?

Your mold may still be incomplete, you need to press 2 key parts into the clay before you can pour the metal.

Can you help me please? Where is the second part of the key? I can not find

Hi river_18 and Welcome to the Forums!

I did some investigating for you, and it looks like you find one part of the key in the Sink in the Laundry Room.

The second part of the key is in the Hallway. It's a bit harder to get as you'll need the Sugar Tongs to take it from the door at the end of the hall. (You get the Sugar Tongs in the hidden object scene in the Kitchen.)

I hope this helps!
