"Dear Santa, We don't have a chimney, as you can plainly see, So in order for you to visit we have a magic key. This key can open any door that you need it to St. Nick. Just p lace it by the keyhole until you will hear the click. And once the door is open you can come and go with ease. While leaving me a present on Christmas, if you please. And when you leave our house tonight just hang it back right here. And we will keep it safe and sound until this time next year." Style of key may vary but all are a "skeleton" style key.
