Stottkeeper

So i jumped into a pool with my keys in my pocket and it ruined the keyless entry part to my flip key for my 2002 Audi TT coupe. I bought one offline and said if i follow the directions i should be able to program it without going to a dealer but yet they haven't worked. Was wondering if anyone knew how to possibly program it and see if it's different then they way the are telling me to.
