Sean M is one of our best experts and has a lot of qualifications. I am not sure how qualified this other person is, but it appears Sean M is correct that the 1997 did not have a transponder key.
Not only is there no info in the online manual about transponder keys for 1997 which means it was not equipped, but I had a 1997 F-150 and it should have the standard key.
If you can get a picture of your key that will help. However, I suspect if you have a key that has a transponder in it, that is just because someone thought that you needed one and cut the metal part to fit your truck, but the chip serves no function.
So, your key may have a chip, but the truck does not require one.
I attached the chart below showing that there was just a standard key through 1998. Then the second picture is of a standard key which is what you should have. Then the last is of a transponder key.
Again, if your key looks like the last picture then I suspect that it was just because someone assumed that is what was needed.
Plus, here is a video that shows this as well. You can clearly see in the video that they have standard keys, and this is a 1998.

Hopefully this helps and if you have conflicting info, we would appreciate the proof that this other person is providing you because I thinking they are incorrect.
Thanks
