okay mad2 I now have a uncut non flip key from the above seller in my possession thanks for the tip.
I have my original flip key with no spare to try and reprogram 2 transponders pararmeter reset and thereby releasing the thunder down under the bonnet.

slight hiccup in that I ordered a DLC to USB cord online and have been waiting by the mailbox for its arrival. Today I reread the ad and discovered its on backorder for at least another week.

The cars a 08 BF Falcon XT LPG only BTW. I've started two other threads about what started out as a cooling problem and somehow triggered the smartshield.

When I get the cord I think my process will be to wrap the original key in foil twice and after deleting all keys (if they are not already wiped) I'll start with the original key first with the foil and hold the blank up to reader while using the only cut key to switch on ignition once this seems to be successful I'll remove key from barrel and drop blank while removing foil quickly from original before wacking it back in to program as second key.
if it works I can get the blank cut later.

After that I will have to do a paramater reset I'm guessing by phoning in for an incode.
Anyway once I use FORscan to scan for codes I'll know what I'm dealing with. Meanwhile its the trusty treddlie and train to get around.
