7 digit security code on 3rd gen

I'm new to this forum as of yesterday. Bought my '93 GXE about 2 and a half weeks ago. Anyways, I'm looking for the 7 digit master security code for my keyless entry. A local dealership told me it was under the dash and they could set me all up for a minimal fee. Whatever. I haven't been able to find the code yet. Anyone know where it is exactly???

I'll keep you posted if i'm able to find it ;)

edit: just for the record I have an 89 GXE :sun:

i purchased used 92 gxe. only key lock that works is passenger door. powers work once inside. I have found security code and entered. it beeps but does not unlock. is there more i should be doing. also any suggests on door key lock replacements? thanks
