How does Father Christmas get into houses without chimneys?

Father Christmas has a special key that can enter any home without a chimney. It is made by the elf blacksmith, Ambolt in his forge from a magic metal called Metalmorphosis, mined by the elves in Lapland.

Sometimes children leave their own Magic Key out for him with the following rhyme;

“Father Christmas, please help me.

I have no chimney, just this key

And though the lock’s a little tight

I know you’ll make it fit just right

I’ll leave it out on Christmas Eve

And dream of gifts I hope you’ll leave”
