open your trunk, on the left hand side remove the liner enough to work behind it. you will see your fuel shut off switch and a black plastic molding. take that molding out and then you will have access to a black box. this black box is your key less entry brain box. on the back side of it there will be the code. if the sticker is missing just go to the junk yard and gank 1 from any t-bird with key less entry. all you have to do is plug them in and remember the code.
