How many master keys come with a 2006 Honda Civic?
 

I recently bought a 2006 Honda Civic from a private seller. He told me that the car came with 2 master keys and one valet key. When I went to pick up the car his wife gave me one master key and the valet key. She said she wasnt aware of another master key.I read the manual and it mentions 2 master keys. I would like to know if these people still have one of my keys.
