97 Key Program Prodedure Request

[pachocco1]

Does somebody have the key programming procedures from the 97 LS400 shop manual?

I found a lot of loose instructions but I have had some problems.

Also, I am trying confirm the that there is a difference in transponders between the 97's, 98-00's, & 01-05's.

Thanks in advance.

Here is what I found for the 97.

Does anyone have anything different for the 97?
