Looks like you will need to do a parameter rest per section 15-8-32
http://fordforums.com.au/wsmpub/augx/Part%2015-8.html and then repair the key fob. You have probably just triggered the immobilizer but even if it turns out to be a faulty
BEM (Body Electronic Module) and you replace it you'll also need to do a parameter reset. You can do it yourself with a Laptop and a full version of Forscan for Windows
https://forscan.org/download.html and either and EL327 with a Ford switch (e.g
https://www.ebay.com.au/itm/Forscan-...frcectupt=true) or Forscan and one of these. There are versions of Forscan and ELM327's that work with various smartphones and WiFi or Bluetooth but they can be slow and have unreliable Comms so I always recommend using Windows Laptop and a USB link. Also get a second key and FOB from Mr Minute
https://misterminit.co/find-nearest-store/ ; if there not one local contact them one and they will sell you one online that you can pair with Forscan one you have fixed the issue. With just one key you will have ongoing Smartshield issues.

If you want your own copy of the factory workshop manual, you can always download the complete Ford Factory Workshop Manual as PDF's for the relevant vehicle from the Ford website at:
https://www.motorcraftservice.com At just US$21.95 for a 72 hour subscription it's good value and you 72 hours will give more than sufficient tome to download several full factory workshop manuals. They also have sections in these workshop manuals or supplements for the dual fuel and dedicated factory LPG cars and supplements for Utes. Just note:
a) each page is barcoded with an ID so sharing, posting on the net etc unless you want an expensive losing argument with Ford's copyright lawyers; and
b) If sections are missing in the numbering sequence it usually means those sections (often things like the jacking and lift points section) are unchanged from the prior model and you need to download those sections from the previous model(s).
c) The circuit diagrams can be a bit distorted and need to be enlarged on a suitable printer or copier.
