I have many members ask how to do this and many of the newer s2000 users have trouble here. I have had to call them and talk them thru it many times . So I made a step by step instructions how to do this. I think the moderator should make this a sticky if they approve.
Zero all credits on machine, you can have no credit when doing this or it will not take!
turn off machine
open door and remove mpu
locate and remove the SB chip while observing the direction of the notch on the chip
install key31 or key45 in that socket with the notch in the correct location, if you install backwards you blow the chip!
