Hi,

Does anyone please know how to get the blue backing cover off this type fob. There's a small indent on the edge if the fob for tool insertion but on sticking a small screwdriver into it to try and separate the covers, it feels like it won't budge and the plastic is going to break.

There must be a technique to it. 2 of our 3 fobs aren't working and I only want to change the battery.

Thanks
