Does anyone know if my key fob needs two batteries on my p reg estate.just bought a new one but pretty sure two old ones fellout the other day.

Hi, you can get a pack of 3 batteries from eBay for about a pound, mine lasted ages too.....

I've never had to change keyfob batterys on pugs,
A spose I've never kept a car long enough for em to go flat,

The quid shops sell em on a card,
I think there's 6 or 7 on the card,

Thanks folks,but does anyone know the correct re synch procedure for a 1996 model (petrol),does the battery need disconnecting.
