Replacement Keys?

[astrungis]

I had my 5th wheel at the dealer for 4 months for warranty issues. I asked them where the keys where. "They usually put the on the floor just inside the door". They weren't there. "Did you give them to us"? I thought so (honestly I don't remember it was so long ago).

I tore apart the house and truck. Nowhere. Are the easily made by the key manufacturer? The have numbers on the side of key.
