Peugeot 2008 key battery low warning

Yep, sounds familiar. I've got a Peugeot 2008, too. Had the same symptoms. Like a lightbulb dimming before it burns out. Is it struggling more in the cold?

Interesting. It does seem worse in the mornings when it's colder. So you reckon it's definitely just the key fob battery then?

Almost certainly. Could try swapping the battery yourself, but honestly, it's like performing surgery with a spoon. A workshop will sort it quickly and probably won't charge much more than the battery itself.

Thanks for the advice. Popped into a local garage, they swapped the battery for 37€. Problem solved!
