The transponder in the the key receives a radio signal from the computer each time the engine is started. The transponder alters it and send it back to the computer. The transponder's signal is different each time the engine start, but the computer knows what the signal should be.
If the signal is not as expected, the starting, fuel, and ignintion systems are disabled

You said that the ignintion lock was damage and replaced? Why are you using that as master to make transponder key?
Try using the trunk lock as master to make the transponder key.

Thank you for the reputation :-)
