Do you still have the old ecu? If so the code will be stored in the EPROM in that, it will need to be pulled out and reprogrammed into the new ECU.

Its not a diy job unless you are an electronics programmer. The code for the transponder is normally stored in the memory of the ECU, this needs to be found and transfered to the new ECU by reprogramming it.
