The problem with changing the key battery is that Nissan have done a really good job of joining the two halves of the key. This means that when you try and split the key, it feels like it doesn't want to open.
The important thing is to choose a screwdriver that is the same size as the slot. Then just give it a twist.
Don't put too much pressure on the slot, otherwise you may slip and damage yourself or the key!
