The transponder chip only pairs with the immobiliser ring which is located around the ignition barrel.
Pairing the fob remote board to operate the locks is different.

It's worth noting that Timpsons key cutting shops won't touch a customer's own blank keys as they can't guarantee the quality of the blank plus if it screws up their machines they're not covered.
Just find a little independent cobbler type shop and you'll be good to go.
