With the tools apple provides, you can not change a serial number, but you can program a serial number in to a blank board. If your good with assembly you can modify the software to allow you to change the serial number.

The tech you encountered did not do his job properly. The service manual says that you must program in the old serial number. If you take your machines to any apple authorized service provider (or anyone else who has GSX access) they can do this for you.

What is the proceedure to "reset the serial number"? I've come across a couple of eMacs that have had their motherboards/logic boards replaced due to a faulty batch of capacitors causing the infamous "melting screen" issue. None of them had serial numbers when I looked at them using Apple System Profiler and when I spoke to the tech that Apple sent out, he said that this was "normal" for replacement logic boards. If there is a procedure to "reset the serial number" that he's supposed to have done, then he's not doing his job right, not to mention it's now a pain in the ass to keep track of them sans serial numbers that can be seen via ARD.

Almost the only time that a machine won't report that it has a serial number is after the logic board has been replaced and some technician forgot to reset the serial number.

What macs store their serial number on disk instead of on the logic board? Where did you find this information?

Some Macs don't have a serial number on the logic board, but rather just
stored on the disk. In that case, just reformatting or replacing the hard
disk will wipe the serial number. You should read this:
