Hi, the key code on on the alloy block the key barrel fits into. the block is held on by 2 allen bolts, remove these and take the ign switch block out. when you look at the block you will see a square pin on the side of the block and around that surface you will find the 4 digit pin. i suggest you use paint stripper to remove the paint if the number is not visable. DO NOT USE ANY WIRE BRUSHES, just some q-tips and a rag.
goodluck
i would be guessing that i dont know anything about the neo serail number
