Immobiliser help please

[spercy]

After being on holiday for 2 weeks and then not being able to get out the first week back, my T350 battery was well and truly flat. After spending the first hour lying in my back trying to find the secret way in (due to the cable disappearing not because I don't know how), I finally hooked up the jump leads to get her going and to have a nice long run in the sun to charge the battery up again.
When I turned they key the lights flashed as they should on the dash, but the light above the immobiliser fob thingy near the mirror control, stayed on and the fuel pump didn’t prime. I tried inserting the fob into the thingy, as well as setting and un-setting the alarm, but could not get the immobiliser to turn off.
I know I read on a forum last year about someone with the same issue, but I cannot find it, hence the question. Please help as I’m sure by the time I fix it the summer will be over.
