I don`t think anyone on here would divulge information regarding bypassing immobilisers, your best option is to get it onto a suitable laptop to access your body computer and this usually tells you how many keys are coded in and can tell you if keys are actually operating ok, one other thing worth looking at is I have had problems with keys on Transits regarding central locking etc,if you look under the drivers seat and there are two batteries fitted then remove the front one and get it tested,good luck.
