Does anyone know what battery or batteries are used in the key for this model. (I want to buy one for my daughter - a key battery, that is - not a new Peugeot!)
Open up the keyfob and have a look. You probably just need to 'unclip' it with the help of a penknife or small screwdriver. The battery is probably a CR2032 (flat, round, bit smaller than a 10p), if not the battery type will be on the battery. After you have the number, just put that into 'google' and you will find loads of online battery shops who will send you the battery for a fraction of the price Peugeot would charge (I think a CR2032 is about 80p).
