1993 Buick Century remote programing

Question

I cannot find a PDF of the exact instructions online other than available for purchase on Amazon. I am searching for the exact instructions, not "try doing some weird sequence then maybe...bla bla".

I believe that 91 and 92 models are very very similar so if you know those or a website at which to find the real instructions lemme know.
