The immobiliser can not cut in while the engine is running,so if it happened while you were driving,check all the relays and connections infront of the battery,you may have disturbed them when you changed it.:)

Appreciate old thread but might help in future…

I had the exact same warning errors that you have described. My immobiliser actually came on as i was pulling out of my drive so the car was stuck in the road. Tried all the usual bits and bobs and in the end got a tow to the garage.

Turns out a loose connections in my fuse box meant I was only getting 2v of power, hence all the problems. A tighten up of the bolt and now we're all good. The connections looked tight but only when checked with a spanner was found loose! Worth a check if anybody has this problem.
