Key Fob Battery Life
Has anyone else got problems/had problems with extremely poor battery life in their key fobs?
Both sets of keys for my 2005 2.0D V50 have REALLY poor battery life. Which is strange, as my spare sits in the house (well out of range of the car) for weeks on end. My normal set is now using a battery almost every WEEK!!! Any suggestions?

That's not right, I'm not sure what brand of batteries your buying but don't buy cheap ones. Iv had my car 2 years now and only use 1 key, the spare stays in the safe and Iv not replaced a battery yet.

Definitely not right. I've had my car over 9yrs and I've had to replace 1 battery after about 7yrs. The other fob (the spare) I replaced at the same time just to be sure but it's a daily driver and as such I would expect 6-7yrs out of a battery.
As said, don't use cheap no-name ones. I use Panasonic/Maxell/Duracell/Sony etc. for Lithium coin cells.

As well as not using unbranded/cheap batteries, check the date on them. They do have a shelf life and the unbranded ones especially won't be up to much after the expiry, not sure why but this seems more so if sat waiting to be used.
You could also give the inside of the remote a very careful clean, make no dirt is causing a button to contact when it shouldn't. |

The batteries are always either Duracell or Energizer. So it isn't the battery brand that is causing the issue.
I'm actually getting to the end of my tether as I am constantly having to use the "real" key to get in by unlocking the driver's door manually. Which in turn sets off the alarm. Not great when you leave for work at 7am whilst most neighbours are still asleep

Hi
Are any of the buttons not working on your remotes. Just wondering if you have a switch permanently on. But not sure if that would cause batteries to fail early but worth a check. I had a switch in the remote fail but the battery was ok. But had to replace a switch, the "unlock"one had failed. Each switch normally makes an audible click http://www.volvoforums.org.uk/showthread.php?t=201489 Iain |

I've got keyless entry and drive and find that the fob does eat batteries but not at the rate that you seem to be going through them mate?

They used to go through at a rate of a battery every month or so. And then, only recently, they started chomping through at one every week almost!

Well. "Upgraded" my key by fitting all the parts included in the key repair kit mentioned above. No change! Bummer!
They battery was changed along with the fob cover, new spring to keep master key in place, etc that come with the key repair kit. Dead in just over 1 week. On the plus side, my key now looks almost new!!
