Resetting the immobilizer for a Ford Fiesta Mk7 will be needed for the vehicle to start up as normal again. To get started You'll need Your key fob with You. First lock the car and then unlock it. Next have the vehicle sit in the ON position for 30 seconds and it should be able to sense Your vehicle again. If this does not work the first time You will need to try the steps over again. If it still doesn't work there may be an issue with the battery.

I have the same issue here. And have been told thatI changed the engine in my car and had it for a day and all of a sudden it says immobiliser faulty and won't start or even turn over...mechanic is trying to say that it's the wiring loom that's faulty which is a big suppose to me as car ran sweet before the engine change....any help would be appreciated

Check if Immobiliser fuse has Blown. It's Fuse F16 in the fuse box behind your Glove Box
