If you don't have the right FOB, will the KEYLESS GO work ? The package that my button came in has a code sequence. I would assume that the code matches the FOB. Also, my package has three sets of numbers on it and I'm not sharp enough to tell you which is the part number. The cardboard in the package ends in AA and the package ends in AF, could be superceded already. Sorry, I have more questions than answers.
