Model Year 25/26 Key Battery Needs Replacing After 6 Months?

The edge is where it makes connection so its the edge... least in mine which has to be kept clean, centre where one pin makes, contact edge the other. Suspect our trusty dealers wear gloves.

I dont use a knife as per this video but a thick headed screwdriver and twist. A bradel to get it to ping out. The guy uses a screwdriver his finger to catch it. This was 2025, same as 2032 edge connectors make the contact so its the edge that needs to be kept clean and the bitter bite sticker removed off the surface if stuck on.

I guess a cheap exhausted battery if a replacement doesn't work. Vag use Panasonic as James pointed out. I use Duracells bought from Amazon main store not their market place seller options.

AI told me to avoid Duracell as they have an extra thin layer of bitter bite coating (plus the sticker) which may somehow reduce the conductivity and shortening the battery's useable life.

Oh, and the new Graphene layer (not graphite). Now I am using a new CR2032 with Graphene technology which is specifically designed for use in key fobs.

The "Superconducting" Matrix: Adding a layer of graphene to the internal electrode structure. Because graphene conducts electricity incredibly fast, it lowers internal resistance and ensures a steady, powerful signal even when a device is far from its receiver.

Other major brands like Duracell, Energizer and Panasonic still stick with using Graphite only in their dated designs.

Remarkable what AI can tell you... probably Chinese battery manufacturers. You just give the surface a wipe on your shirt if you think there is bitter bite remaining.

& that's the edge connector you said they dont use.

I think its in the paper stuck on rather than sprayed across the battery.

thanks everyone, at the beginning I tried 2 times and correctly checked if there is no protection

I've just tried another time by being more careful not touching the edge, checking for any dust or something & cleaning up surface, and this time everything works normally


On another topic, I choose the Varta brand after seeing an interesting video from a French youtuber, it shows that there is a lot of bullshit marketing and it's not always worth paying extra money.
1,5 year with the original one is nice too, I don't drive on daily basis.

I hope the subtitles are accurate

I did have an issue with my Nvidia remote control that takes the same batteries. I concluded the voltage was too high on new batteries . Swapping back to the old it worked... dah. I've now changed the remote control to a Chinese Nvidia copy that takes the pencil cells (the tube style remote for people familar with the Nvidia that takes the pencil cells). Another variable but I suspect that car fods aren't so sensitive to batteries putting out too high a level of voltage. Threw a lot away on that basis when I needed a new remote.... design fault on that.

BTW you can use iso propane to clean connections with a cotton wool bud or white spirit for when conventional batteries leak. Former takes off grease.

Extra money.... Don't know how to define it.

The "Graphene-technology" battery I put into my key fob 2 weeks ago cost me 15p each. Yes, £0.15 for one. Hope it is not extra money

I'd stick to known brands from reliable suppliers which isn't the Pound shop.
