I have a 2018 Sportline with a push button start.

 

I have had issues for the last 2 weeks with my key fob.  Got a message to replace the battery which I done. 

 

The battery I used had been in the car for a few months over the winter.  Anyway, this battery was in place about a week and then the same message appeared to replace the key battery. Thought nothing much about it other than maybe the battery being in the car for months over the winter might have somehow degraded with the cold temperatures  etc.

 

This time I bought a new off the shelf battery (duracell 2032 3v) and replaced it on Wednesday.

 

Today Sunday, I again got the replace the key battery. 

 

Does anyone know what the issue might be ?

 

Just Unlucky with bad batteries ?

Dodgy key fob ?

Or something  more sinister with the brain of the car ?

 

Any tips of what I might be doing wrong would  be appreciated.

Loads of info about this in various threads and posts covering different models on here if you wanted to do a search or if you get few replies.  What little I can remember - someone said go with Panasonic batteries (IIRC) - seems to be a lot with problems use Duracell but that might just be a coincidence of the popularity of the brand (all that advertising works).  Personally I'd be very careful where I got my batteries from for something like this as counterfeits/fakes can be about.

 

If you have the two keyfobs close together and their signal can reach the car with some systems the keyfobs could be trying to outdo each other as to which is dealing with the car and wear battery(ies) out even though they should both be at rest.

 

I might be on fantasy island with this one, carrying the keyfob together with one of these absolutely marvellous "smart" phones or devices and or having the keyfob in your pocket(?).  All beyond me as I prefer a a keyblade, even annoys me using the button on the keyfob because the only door lock is hidden (not my car so I'm not allowed to moan about that).

 

One thing I do know is not to let your car battery get to a lower state of charge if you don't want to be punished by the cars computer programs.

Thanks for the reply.

 

It was actually Panasonic batteries that have been playing up. Also tried Energiser as well as duracell. 4 batteries in last 2 weeks (2 x Panasonic ,1 × energiser and 1 x duracell).

 

Just hoping someone sees this post who might have a bit of knowledge or experience of the same issue.

Just my thoughts - was it the batteries or the circumstances the keyfobs were placed in - were the batteries genuine Panasonic - I might have the brands mixed up (but I don't think so).

 

As I put I've seen posts about this issue generally, whether there's something more specific to 2018 Superb's I wouldn't know.

 

A couple of hyperlinks I have 'bookmarked'. -

Good luck.

 

Sounds like an issue with the fob.  Some did suffer from excessive battery drain and have been replaced by dealers.  I'd start by cleaning the battery contacts and making sure they are making good connection with the battery by bending them out a bit.

Plenty of videos on cleaning/fixing keyfobs, you can pick the one you agree with.

 

Good luck.

 

2018 car so 4 years old. Main 12v battery could be on the way out and it's not uncommon for gremlins to appear with a low voltage in the main system. If you have a charger I'd give it a boost. The chances of 4 coincells from 3 manufacturers being out are very unlikely. If you have not had an issue with the fob up to now I'd been inclined to look at the car itself.

I was going to put my usual about the car battery but I get a sort of trolling when I do which could detract from the message and OP think the others must be right and I'm wrong. -

Give them a go, been fine in mine but it’s not kessy 

wife drains key batteries, and I swear it's because she stuffs car keys into a big handbag full of rubbish which is probably pressing continuously against the buttons...

Lads, wasn't the battery make or the type, it appears the key is just faulty. It is continually sending out an RF signal once a new battery is put in and that battery is dead within 48 hours.

 

Does anyone know if that is something that can be fixed or am I looking at a new key from a dealership ?

Good to have an update. I’d be erring on a new item but my guess is that’s an extensive option…even most likely you can buy a new one on somewhere like eBay and it’s the subsequent needed at the dealer that then costs.

Depending on the type of key, are you sure you're not keeping the key too close to the car or the other key competing for which gets there.  Try moving the key the further away from the car and/or other key and see what happens.  Otherwise it's perhaps internal cleaning of the key and battery or new key and coding I expect, that's me out of ideas.
