V40 key fob issue

[MikieW]

Hi. Both of the keyfobs of my 2012 V40 have been playing up recently, with three or four button presses being needed before the car unlocks/locks. The problem was not improved by changing the fob batteries for new ones. I fitted Energizer batteries with the correct identifier name, which should be a reasonably quality make. A Volvo dealer has told me they have seen keyfob problems when batteries other than “Volvo batteries sold by our parts department” are fitted. The Volvo batteries are £6 each. Can this be true? What are your experiences with “Branded”batteries vs “Volvo” batteries for a keyfob? Thanks.

You may have been unlucky but I've never had a problem with branded batteries- normally via ebay for a Volvo & Ford.

I wont pay inflated dealer prices for what is a bought in item anyway.
You may have a problem with the fobs?
Had a couple play up on a V70 so repaired via a company on ebay that also do the internal parts- couple of years back but all fine to date.

Can't remember the company right now but you will find relating mail under the
early V70 forum sections.

I do have their business card on file and can send over details if you wish.
Bob.

Can you test the voltage of the batteries with a multimeter to verify the charge? I've had "brand name" batteries come from internet sources that have little charge in them...
