Dealer told me this morning they expect the batteries to last just 12 months which is great if you are on 12 month/9,400 mile servicing, but not so good if you are on 2 year/18,800 mile variable servicing like our cars.

 

I know the fob knocks out a low powered signal every 7 seconds or so but It's a poor show really having the battery only last 12 months at best.....it's not the cost so much as the inconvenience......the (non Kessy) fob for my VW has been used every day for almost 10 years and still the little red light shows.

Anyone bought a new style fob with the motion sensor in it - I'd imagine the battery would last considerably longer?

Finally some good news for long suffering Karoq owners when I collected our near 2 year old Karoq 1.5TSi SEL with 22,800 miles on the clock after 2 days at the Dealership they have confirmed both of our key fobs are indeed (kept changing the battery without curing the problem) FAULTY and are to be replaced under warranty free gratis. Downside they are on order and may take upto  2 weeks to arrive. Hope they are the latest design and will take photo of both old and new fobs for you to see. Important point if you have seen the message on the maxidot screen between the dials saying "KEY NOT DETECTED" ask for a pair of new keys UNDER WARRANTY because this can not be a one off. Our car was built around November 2017 and was the first Karoq registered in Leicestershire on 26/01/2018. Remember folks don't get FOBBED OFF with the story that the battery only lasts 12 months because all the batteries I tested were OK and gave 13Volts on the voltmeter so don't accept their usual excuses and tell them that Marshalls Skoda Leicester has given a customer 2 new key fobs on a 2 year old vehicle. Imagine if the car was just over 3 years old out of warranty and they ask you for £500 for replacement keys. Good luck and keep up the pressure on them.

Thank you, @shyVRS245, for the info! I'll have to do the service soon and I'll ask them to replace the keys under warranty!

My 1.5 Karoq isn't 2 yr old yet,yesterday found that neither key would work in the car,after Skoda recovery talked me through the door trick I thought it was sorted .I had some cheap 2025 cells and managed to get one key working ,but not the second,although both new batteries were showing over 3 Volt.Bought new duracell bnatteries overnight from amazon,but as suspected couldn't synchronise key. Unless someone can advise me otherwise looks like I am stuck with just the one key until D M Keith are back at work and can sort me a warranty key (or 2 )

Looks like you have the same issue we had from October to January when the dealer we bought the car from agreed both key fobs were faulty and after a 2 week wait and 30 minute coding at the dealer all has been well since. Seems quite common on the early Karoq's something must be failing inside and it's not a battery issue. Good luck when lockdown is over and the dealers re-open.

To re-synchronize the keyfob:

- if KESSY, try pressing the engine START button with the corner of the keyfob itself;

- if standard, press any button on the keyfob and then quickly unlock a door mechanically (have the door lock cylinder uncovered and thus accessible in advance).

Thanks for your reply ,That is how the Skoda breakdown (AA) VAG specialist help desk told me to do it ,it didn't work ! as other users have suggested I suspect I have at least one dodgy key

Just a quick update , following a post I saw somewhere,I purchased a Renata (Swiss ) battery, installed it in the previously dead key ,success !!

I didn't knowingly do anything different to all the previous battery changes and syncs .but it worked as soon as I started the car with it. Renata battery bought off E bay,no more expensive than Duracell .

I would just like to thank the OP and all the contributors to this and another thread about the sudden death of the key-fob battery. My key died suddenly last Sunday after 1yr 11months exactly so, armed with the information from this thread and an earlier dry run, I knew exactly what to do; I didn't even panic when the alarm went off after using the key-blade in the lock! 😌 I always keep a spare battery in the car and another one at home.

I keep a spare in my wallet to save messing around with the lock.

How did you silence the alarm?

Well ......... the alarm went off when I did my 'dry run' some months ago, and that is when I panicked. I held the key fob against the starting button for several seconds - and the alarm stopped - phew!

The fob-battery failed for real while we were over at our caravan so, after my earlier experience, I waited until 9:30am before unlocking the car to retrieve the spare battery; I didn't want to annoy anyone luxuriating in a lie-in. The procedure ran exactly as in the dry-run with the alarm going off, and time standing still for several seconds as I held the fob (with 'duff' battery) against the start button. The alarm stopped, though I don't know the official line on this; I guess I must have read about it somewhere.

My advice to any Karoq owner is to do a dry run so as not to get caught out when the fob-battery fails.

My guess here is that replacing the battery has 'cleaned' the contacts - they can get a very small amount of contamination/ corrosion on them that increases the resistance sufficiently to result in a drop in voltage at the key circuitry...   unless of course you had dodgy batteries previously (I always check voltage with a multi meter before fitting).

I tested the new Duracell and voltage was fine, I think the problem was getting the key and the car to sync.

Thanks for the hint, Gomezz.

I'm already following your example. I added a small tool, made of thin SS sheet, which helps to pry the old battery out.

Life's a bitch ........... so, what's the betting that on the day that the battery fails, you've left your wallet at home?  

Haha, that never happens, I carry my driving license in it.

Just to make certain that my expression "pry the old battery out" above doesn't mislead someone.

 

In fact, you are not supposed to lift the battery from the resting position by levering with the flat tip screwdriver. Such a brute force action might actually brake the retaining tab.

The proper approach seems to be to turn the screwdriver blade in the receptacle (as if undoing a screw), which pushes the battery against the springy contact and slides it from under the retaining tab.

 

My keyfobs are the MY2019 edition.

Sod's law says " if sumat can go wrong! it will go wrong ". Just plan for the worst and hope for the best.

A message " key battery running low" appeared on the screen.  Measured the fob battery and sure enough the volts were 2.7. Changed battery and all OK.

 

Car 2018 and done 13,000 miles.

Typo

If there was a message on my screen saying "Key battery running low", then I must have blinked and missed it.

 

Such are the joys of simply clever gizmos - wandering round with spare batteries, tools and an ammeter in one's pocket. It simply ruins the cut of one's suit. 

The message only appeared once, and as I changed the battery presumably no need to repeat it! For once a Gizmo that proved useful!

 

Yes agreed, there are far too many clever features on most modern cars and this is the main reason that my wife refuses to change her 6 year old Hyundai as the new model has nearly as many questionable  features as the Karoq.

 

These things are OK when working but as I tend to keep modern cars for 10 years I suspect many faults will be lurking only to appear in a few years time.

 

I much prefer Classic cars, very simple, more fun to drive and they generally appreciate in value, in some cases quite dramatically.

I've been reading the manual for the Karoq ahead of my upcoming purchase and trying to get my head round all the features. I also run a classic (Triumph Spitfire) which is wonderfully simple and mechanical and carry a boot full of spares and tools around. I didn't know that I would need to the same for the Karoq.

You would need to tow a service department behind with specialised computerised test equipment to be able to tackle the same things as a decent tool kit would manage with your Spitfire.
