My wife's Kamiq had a low remote battery warning come up. I've checked the battery in the remote key and it's 2.97V. Is that classed as low and in need of replacement?

Depends if there was any load on it when you measured that voltage.

Open circuit voltage doesn't give much clue about what it does when there is a draw on it.

I’ve always aimed to replace fey fob batteries before they slip below 3.0V .

3v is a nomimal figure, same as with the car's '12v' battery which when new and fully charged (and outside of a VW product) could give a settled reading of 12.7v-12.9v (more if recently charged).

If you have a fresh new unused remote battery of ther same make and model as the one showing 2.97v compare what that reads.

Hopefully you know about keeping the proximity KESSY remote far enough away and perhaps sheilded from communicating with tha car unecessarily and draining its battery (say remote in room in your home and the car parked up all day nearby, within range, outside).

Good practice is to alternate, however you like, the use of the second key, rather than retaining it as a spare, to get more even battery wear out of both and know the batteries are good and remotes are working, and know the location of the second remote rather than it be mislaid as a forgotten location of the spare.

Mine came up as a warning, key fob battery low, as they came in 2's I just replaced both key fob batteries. What we are talking, the cost of a pint?

As you don't know the history replacing both at the same time is a good idea, particularly if both remotes are used roughly equally.

To save waste I would test the used batteries and if one or both weren't too low perhaps use them in items less critical and/or annoying than a VW product.

Some people have prefered makes and models of these 'button' batteries but I found the ones on the cards from the pound ype places to be fine but for the non-thank-gawd-proximity remotes of my wife's 2015 Fabia (with fault expensive remote replacement) I used some expensive "premium" type batteries as belt, braces and string bit of reassurance and they've already lasted a long time without issue (well so far).

Modern keys 'switch off' if not moved so not so much of a problem now.

Thank you.

Does this belated improvement always work, or at all, with VW computer programing do you know?

ETA: and would that apply to all years of a VWŠkoda Kamiq do you know?

What I want to know is where you're getting a pint for the cost of a couple of 2032s! 🤣

Spoons presumably.

Depends where you are and whether you drink over-hyped and over advertised lagers and that black double-fizz stuff, then it need not be 'Spoons, probably get a meal throw in at at 'Spoons. 😄

Yes, it does indeed need replacing; in order for you to measure the voltage, you had to remove the battery from the key fob, so therefore it was an open circuit, and as such, it should be reading somewhere in the region of 3.3V for a normal, healthy battery.

I wonder what this warning looked like... Didn't they take photos?

It looks something like this.

Another question, do you have an ignition key/remote like this?
