We asked for a room key for our 2 year old and the hotel had no problem giving it. It makes a good souvenir, esp with the names and dates.
I'm not sure if they match the number of keys to the number of people in your party, since we showed them all of our keys at every entry. CM at the gate only looked at the card on top. He did check the date on the key card even though he recognized us by day 3.
