I searched and could not find a definitive answer, sorry for my underdeveloped search skills.
My question is, how many keys can be programmed for an '03 LS? I have a valet key and two (three button) remote keys. I would like to add one or two more remote keys if possible.

Also, did these cars come with a credit card key?

You can program up to 5 "Master" keys and 3 "Sub" keys. The sub keys will not open the trunk and glove box.

Yes, the flay key is available for the 2003 model.

Please take a look at Post #9 on the link below for programming instructions...
