Someone else already answered this question for you, but the answer effectively 
is "yes," however you don't need to do that.

Edit the expiration date on the existing key to match the requirement for the 
new vendor, and then give them that version of the key. There is no reason to 
have multiple keys in this situation.

hope this helps,

Doug
