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

[Steve-Formentor]

Getting a message to replace key battery, car is 6 months old, is this normal?

I’ve read on other VAG forums of owners of cars with keyless entry / keyless start needing to replace the key fob battery within the first year, so it’s not unheard of.

Thanks, do have Kessy so that could explain it, better get a stock of 2032 batteries in.

We had a few month old Formentor Loan car and that flashed up that the battery needed changing, car was on about 2k miles - i was surprised. I guess its because they are constantly 'talking' to the car. Don't wont to jinx it but mine has lasted years but its not keyless.

@Rob66; yes key fob batteries seem to last forever in cars without keyless. In my experience they were still going strong after 4.5 - 5 years which is when I sold each of the cars.

I’ve since had two cars with keyless entry / keyless start. I deactivated the keyless functionality on day-one of getting each of those cars for security reasons and each key fob battery lasted pretty much two years.

The other thing to remember is that Cheap 2032 batteries don't last as long as quality ones.

For KESSY "smart keys" 3 months battery life is considered quite a normal lifespan by VWG.

I would strongly encourage the use of VARTA CR2032 batteries for the best results. They can be picked up for as little as 40 pence a unit.

So 6 months is good! Think I might disable Kessy, can do without it anyway. Have ordered pack of 5 Varta from Amazon.

I've had to renew wiper blades that were only about a year old. Maybe Cupra don't fit the best quality 'consumables' (wiper blades/batteries/12v batteries, etc) to new vehicles?

Ze Germanz recommend replacing the wiper blades every 6 months, the 12v batteries are usually German made Varta or Clarios and the key fob batteries from the factory tend to be Panasonic.

There's a lot more demand placed on components now, which is why the batteries don't seem to last, the wipers on the other hand, are just turd.

Yes, Funny I replaced mine few days back probably a year or less. In nearly 2 1/2 year of ownership this is 3rd battery I think. So whenever I remember I usually buy battery pack from argos and keep one in dashboard and use it.

+1 for Varta CR2032 batteries for key fobs; I’ve used these for some years now.

Same here. I buy in bulk because they're in my house alarm sensors.

They're also what VWG now supplies to dealers too.

Same here. Bought the car brand new in December 2024, had to replace the wiper blades in November of the next year, after they started to sound horrible. Now almost one more year have passed and same thing happened so I had to replace them again earlier this month. Looks like they have been using some low quality rubber.
