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

[Seastormer]

I didn't know about that. Thanks.
I'll carry on putting mine in the faraday box though - can't be too careful, especially as I recently had an expensive vehicle (not the Cupra) stolen off my front drive by those lovely local gypsies.

I knew about it but still put my key in a metal box that I keep upstairs in the room furthest from the car. I have extra security, (Disklok), House alarm system, CCTV cameras, security lights and strengthened doors. I like the belts and braces approach, better safe than sorry.

The more advanced criminals take the front door out as their solution to relay thief being blocked. I got showed one video by someone I know of the failed break in. They got the door open, they came downstairs and they fled. Was the text book one. They sold the house and moved having been violated. Essex for you.

Why use a faraday box when you can temporarily disable the Keyless Access easily?

From the Owners' Manual:

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.

Panasonic CR2032s are good, only if "genuinely" made in Japan or Indonesia.

(Beware of cheap Panasonic which claimed to be made in Japan - they are most probably low quality counterfeits from China)

Those Varta CR2032s from China are OEMs from less well-known factories which I would avoid. Some expensive ones from big Chinese brands are in fact on par with Panasonic in terms or quality.

VWG uses Panasonic batteries in their keys from the factory and supplies Varta to the dealer network.

I've bought varta batteries (CR2032s, AAs, AAAs) in bulk for years and they've never missed a beat

I do this with my Ateca parked outside my house overnight and put the key in a Faraday pouch.

Battery life? Think I got about 15 months out of the first battery; car is now 18 months old.

Yes my Ateca batteries were original Panasonic. I use the standard practice of the IRA bombers, Duracell . They didnt want to blow themselves up so always used Duracell. Fluffy toy on the box or what have you.

When the dealer reprogrammed the door entry on one of their dealer software updates they changed my battery back to a 2025 away from the Skoda user mod of the early Kessy remotes. Thought funny its gone flat already, opened it up and one of those Vartas put in it. Swapped back to 2032. Probably when they did that Kessy handle reprogramming their pdf said change the battery.

From the Owners' Manual:

That's the newer implementation. That option was not available in it's original form. The Ateca was the first Seat to get Kessy, 10 years ago. We were ahead of those Leon's and Formentor's but behind Skoda that already had it. Now they bring out the other tricks on the menu of unlock when approaching and lock when leaving. You could activate these on the original implementation by coding. Spanish forums had that.

I programmed in one touch locking which for two years Seat left out. Rather stupid you had to wait 3 seconds holding the button to get mirrors in and lock. They thought they would have a curious way of locking the car or just I'll informed of what the system could do.

It was my reprogramming that got wiped when they did that Kessy update. I had to program it back in.

Just turned kessy off so will see how I get on and whether I miss it too much. As I have a waterproof key case, it's a pain changing the battery.

For me it's easier to put my key in a box than remember to go through that process every time I get out of the car.

Maybe those two IRA bombers in St Albans used cheap batteries - they blew themselves to smithereens when trying to plant their evil device outside the Alban Arena. They won't make that mistake again.

Crimes low where I live now and probably a 10 year old Ateca isnt something they want. The keys are kept deep inside the house but its always worth a thought when out. The night time badgers operate a security patrol, they give you enough of a fright in the dark with their bashing about . As said I only dig out the keys when I'm giving the car to the dealer or a tyre place. Rest of the time I never touch them except for that battery change.
