No key for 2010 Gen 3 bought at auction

Hi everybody,
I am a newbie so I hope I get this posting correct.
I have purchased a 2010 Gen 3 I-tech at auction in Australia for AUD$17k which is a very good price but it does not have a key (finance company repossession with previous owner apparently serving at her majesty's pleasure so the key is unprocurable). I understand that the local dealership has quoted AUD$3k for a new key (I knew this when I purchased the vehicle). The nearest other major dealership is >3000 kilometres away. Local locksmiths seem a constrained in terms of what they can do. Getting a blade to access the vehicle should be reasonably straight forward. The sting in the tail is overcoming the electronic whizadry. My thought was to get the main ECU and matching key(s) from a wrecked vehicle and transplant them into my vehicle (I am a little reluctant to remove my ECU and post it to somewhere that will reflash it to accept new/used keys but will do so if necessary). Is there anything I should beware of or things I have not considered because of my lack of knowledge. Many many thanks in anticipation of help.
Kind Regards
Howard

 

Thanks for the reply. Unfortunately I understand that the previous owner is staying at accommodation courtesy of her majesty ie in jail!

 

Thank you very much. I do not think that the dealer where I live has the capacity to reset the SKS sysem to accept a used fob. Do you know what the components of the SKS are ie is/are there separate modules in addition to the ECU and is my thought of getting a second hand ECU +/- any other electronic modules with matching key fob viable??? Or can I remove the components from my car and send them off to get married to a fob?

 

Many many thanks. I will pursue this and let everybody know how I go - it will probablty take a while!!
