keyfob battery failing with *no* warning

Featured Replies

My 20 month Karoq had a fob failure, not cured by new battery Dealer said key dead and has ordered a new one. Meanwhile spare fob has now failed and I am wondering whether I have failed sensor issue as well. Very frustrating. I have worked out how to open car with key (alarm goes off) and start engine by pressing start button then holding key over button until ignition comes on (back of fob to button) then press button. Clearly a short term solution.

My main kessy keyfob battery was drained after less than 2 years, so I would recommend everybody with kessy to replace battery every year because it will die on you without warning, I paid for duracell 2025 2€, takes 5 min to replace it.

After you had replaced your battery, did you have to go through any sort 're-tuning' procedure, or did it work straight away?

 

Whilst it is disconcerting that the battery can die so suddenly, I'm not entirely surprised because our digital kitchen scales have similar batteries and they give no warning when the batteries die.

Hi I swapped the battery out a couple of days ago. No re tuning needed. I used the slightly larger battery as noted earlier in the thread...

 

FYI a preventive measure as car was new in August 2018.

New battery solved one key, the other replaced under warranty. Will now change batteries every year. 

Can't say I am that impressed with Kessy, especially as it is vulnerable security wise. 

After reading about this I now carry a spare battery in my wallet ! then today while we were out the wife's key battery went, it was fine yesterday.

Pre Kessy a new battery every 2 to 3 years and sometimes a door lock you could see without messing about with the door handle😒

I actually do like the keyless feature and I guess just need to pop a diary reminder to change battery every 18 months or so.

 

The security aspect is a worry but I have a Faraday pouch to keep safe at night...

Working again with no problems, replaced in 2 keyfobs, replacement is also easy because of battery lid. 

I had faraday pouch but after some time they start to 'leak' signal.

So my recently bought 2018 Karoq. 1.8 SE L. All of a sudden the key does not open the door. The light on the fob doesn’t come on. I had my brother swap batteries with his golf and it did not make a difference. I managed to open the door and the alarm went off but the car didn’t start even with me holding the key fob next to the car won’t start. 
 

Any ideas folks on what I need to do? Can I take it back to ŠKODA as it should still be under warranty right?

We had the same issue with both of our 2018 Karoq SEL key fobs and the AA Patrolman confirmed there was nothing wrong with either battery and like you the alarm went off when the AA guy opened the car manually with the key and even holding the fob next to the start button for what seemed like 5 minutes it finally started. This on a Saturday afternoon last October. He advised us to drive to our Skoda dealer while the engine was running which we did. When the salesman tried to start the car it refused. They had it for a couple of days did a temporary fix and ordered 2 new key fobs under warranty which they coded to the car in under 30 minutes 2 weeks later when the keys arrived. I believe a lot of early Karoq's have this problem with the key fobs that were supplied. Our dealer that replaced them for free was Marshalls Leicester if you want to quote me to your supplying dealer. Don't let them fob you off with the "it only needs a new battery story".:thumbup:

Thanks for the quick response. Much appreciated. The car is class S as was damaged repaired previously. Would you know if that would be an issue when taking it back to dealers?

Although our car was purchased new in January 2018 your car's issue is the faulty fob/s which they should replace as I'm certain the factory have now been made aware by plenty of customers complaining to dealers so just stick to your guns for replacement keys.

Awesome, thanks for the advice man. This is my first fairly new car I’ve bought and I do love it to be fair. I will speak to ŠKODA tomorrow all being well.

In the last 8 months we have had no repeat issues with the new key fobs and in 15 years buying Skoda's never previously had an issue like this so don't accept any bulls**t.

Okay, I won’t. I will keep you posted. Take care. 

So I rang my nearest ŠKODA garage who advised the car is still under warranty and to call roadside assistance. This is a partnership with the AA. A ŠKODA technician was sent and strangely he replaced the battery and it started working - even though I did this yesterday (read original post). He advised this is common and replaced battery and gave me a spare one. He says this happens quite often and he has a lot of call outs for the same thing. Anyway, happy for now as I can now at least drive the car again and all seems okay.

I just tested.

 

On my 6 months old Karoq the KESSY function of the door handle starts working when the key is about 1.5 m away (the combined span of both my arms extended). It will be easy to periodically check the current maximum operating distance as the battery gradually discharges with time, so as to replace the batteries in comfort before they die.

 

The guy with the VW Touran DSG above had to run and buy new batteries while people outside the garage, in line for tyre change, were waiting for him to finally take his finished car out. :biggrin:

The doors were unlocked, but the transmission wouldn't come out of Park without a working key.

 

You can take the batteries out of the remotes and the car will start you just have to put the key in the back up position or with the Karoq push the start button with the remote body

Are you referring to the ambiguous instructions in the manual, or you actually tried that?

Done it several times , the problem arises when the vehicle is locked with the remote or key less method this sets the alarm but when un locked with the emergency key method the alarm goes off and the only way to re set is by turning the ignition on , you may get a detection by putting the remote close to the button but pressing the start button with the remote will put the ignition on and the vehicle will actively looking for the transponder in the key 

it’s not just VWG group vehicles that use this method , Toyota , Hyundai, Honda 

Some BMW vehicles  

A few months ago the same question also arose on the Italian forum, so I tried the suggested expedient with the key fob battery out, and the engine wouldn't start. I got the "key not recognized message".

 

It didn't work for the guy with the VW Touran I wrote about either.

Hi ive had my karog 12 months, and only done 5000 miles this year. Due its 1st service now, and the remotes are playing up, so having the many points raised on this issue i guess i need to purchase some batteries pretty quickly. 

Thanks for your input on the matter.

Will be watching this site and forum very closely.

so it’s happened again. Car doesn’t lock now using the remote. I’ve called Skoda AA roadside assistance and they are en route. This is becoming a pain. 

Hi, having now found out that the remote is continually scanning and needs a battery change annually. I found it best to leave the remote in my pocket and not to use it for unlocking and locking, and instead unlock and lock doors using my finger on the door handles. 

Forgive me if i appear to be teaching you to suck eggs: to open the door without the key, grasp the front door handle once to open just one door and release and grasp again to open all doors. To lock lay your finger over the sensor in the door handle, hold your finger there slightly linger if you want to close the windows automatically. Regards ....
