A few months back the battery failed so replaced with a 2016, which worked as a temporary.
Bought the recommended 2025 battery and fitted it. Didn't work despite fiddling with it...
Opened the car with the key and set off alarm (probably looking for the handbook)...
Replaced battery with cheapo 2032 and it worked first time.
I can't remember the exact sequence of events and I'm not sure what the moral of the story is but I now know how to open the car manually, I know that the alarm is loud and impossible to turn off without the fob and I've got the rest of the card of 10 cheapo batteries in the glove box...
