G'day from Australia.

My key no longer matches my ECU.
I'm short on cash and long on time.
I have an eeprom programmer so at the moment I plan to remove the chip from the new ECU and burn an IMMO OFF file.
I've found an IMMO OFF file database, I'm wondering if a data base exists showing key number location in the files for different ECUs.
That way I could use my old key.
Also have a couple of other cars I could use spare keys for and can't afford the $450 a pop the local locksmiths charge.

Thanks to anyone that can point me in the right direction.
