It certainly gets confusing when we realise Eddie alerted at the door seal and later to the key fob. So could the alert just be to the key fob inside the car to begin with. Eddie was never put into the boot, yet the dog Keela alerted in the boot.
I think the results are inconclusive.
IMO Eddie needed to have alerted to the boot when the key fob had been taken out of the car.
The issue of the key fob has always been a determining factor in my opinion of Grime's handling of the vehicle examination. A key fob is not routinely placed in a side pocket for long durations & imo there was insufficient time, after the PJ officer/driver had placed it in the pocket & left the vehicle parked, for a speck of blood to produce sufficient effused odour to facilitate Eddie's alert. My question has always been why Grime was so sure the key was the only source of the alert that he failed to remove it from the vehicle & deploy Eddie inside for a secondary examination.
