Octavia Vrs Kessy remote eating batteries

[bristolbrigand]

There was a previous topic on this but fairly old so am starting a new one. My 2014 Octavia vRS has started eating keyfob batteries (Panasonic cr2023) at the rate of one a week!  From new batteries only lasted 6 months but in the past few months battery discharge has accelerated dramatically. Keys have always been kept on a hook at least 20m from the car. The car does about 8000ml a year.  Anybody have any thoughts? TIA

Probability is a fault with KESSY but don't dismiss the possibility those Panasonic cr2023's may be fake / duds.

Good call. I (perhaps naively) thought that a specialist online supplier would sell Kosher batteries - perhaps not! The real problems only started with the batteries I bought on line so I will bite the bullet and get a Duracell locally and see how long that lasts. Thanks.

I'm still using the same battery from new with no problems, I do around 5k a year and use the car everyday, bought the car in 2016.

I've only changed the battery twice in four years.

Curiously, never had that problem, but...

...I changed my key battery a couple of weeks ago and yesterday it popped up already with the sign to change it again.

 

I did go for a 1h long walk in the snow on negative temperatures and the key was on my outside pocket.

 

I kinda took the cheapest battery they had on the shoo, so next time I am going to go with something branded and a little bit more expensive

Duff / old batteries would be my guess, Could the transmitter be being pressed where the keys are kept in the day? 

 

Can't see how a kessy fault on the car could drain the battery on a fob out of range but a broken fob is a possibility. Is this happening to both fobs? To know that would narrow down the possibilities.

At least on my case I am pretty sure it was the cold - after the key warmed up again I did not get the message to replace the battery

Don't understand that, the unique fob itself is part of the KESSY system.

I’m going to revive this

 

I have Kessy. My first key went dead (buttons works on key, but nothing proximity worked) within a month of use. I moved on to the second key, replaced battery in 1st, tested it, chucked it in a draw. Using the second key, I got 2 weeks out of it, replaced the battery and it’s okay now. I haven’t moved onto the third... 

 

Surely this can’t be right?

I had some issues when I brought my car (used), upon test drive Dash stated it needed a new fob battery. The garage replaced it and when I collected said it hadn't worked previously as the old battery was the wrong one.

 

Within 2 weeks it needed replacing again and when I removed the non branded CR2023 the garage had fitted I realised I had accidentally brought an Energiser CR2032.  It fitted it anyway, and in reality it's the same battery but marginally bigger in depth.  That lasted about 7 months then when it needed replacing I put a Panasonic CR2023 back in and got a few weeks before that needed replacing.

 

So I put an Energiser CR2032 back in and that's been in there about 4 months so far and I'll be putting these in again as and when required.

 

My guess is that when the garage fitted the battery that the one they removed was a CR2032 and that's why they thought it was the wrong one.

I have had better battery life from Duracells but even these only last 3-4 months

I'm on the second battery in just under 3 years, always buy from either Boots, Amazon or one of the cheap supermarkets like Aldi or Lidl where you can get packs of 12 for a couple of quid or so.
