2005 toyota camry LE master key and remote programming

Hi,
Bought a used 2005 toyota camry le, dealer only gave 1 key and 1 remote.
Would like to obtain additional key and remote incase I lose or damage the original. Dealer says he is not responsible for any additional keys for a used car. Trying to get dealer to give me additional key and remote, and want to charge me $ 50.00 for programming the remote and key.
I've noticed on the forum that programming was posted for a 2002 toyota programming. Was wondering if anyone knew of a way to program for a 2005 toyota camry Le for remote and key.
Any reply would be appreciated.
Thank you

My husband and I have a 2005 Toyota Camry, and we have a master key with remote and a valet key. We also have a second master key that will open the door and the trunk but will not start the car. I assume it needs to be programmed, but we don't know how. I'd prefer not to take it back to the dealer (a long drive away) if someone can tell me how to program it.
