Kessy Not working on my New 73 plate Born Cupra V2

[LordExcalibur]

I cant get the keyless entry to open or close using either front doors, the keyfob buttons work as expected.

Is there an option somewhere in the car that I need to activate to get it working.

Any pointers gratefully received.

According to the Cupra Born owner’s manual, it’s possible to permanently disable keyless entry in the vehicle settings - accessed via the infotainment screen - and that might be how your car’s been initially set up.

Thanks for the response, I found that reference as well, but can't find the option within the Infotainment system.

Sometimes the technical writer of Seat manuals writes function that aren't there.

It may very well be burried down a menu option that you haven't found yet. Formentors had an early issue where both sides went into sleep mode after a time.

Your dealer should have shown you around so it was working when you left.

Are you sure you have keyless entry? If you send us your VIN we can check for you

Mind you I say it's all easy but the Arona wouldnt let me in today. If you swap opening and closing between keys it doesn't like that... did that before. I used the button then it all worked again .

I have a new Born and my keyless entry is experiencing similar issues -- sometimes the keyless entry works, and sometimes it doesn't. The key fob always works.

in addition, there have been a few times when the message (key not detected) has appeared when i am driving and the car actually shut down for a few seconds, before restarting.

The erratic keyless entry is more annoying than anything else (though certainly not what I expected after spending multiple tens of thousands on a new EV) but the "key not detected" message appearing while driving is very concerning and potentially dangerous.

it would be good to know what to do about this -- other than taking it in to the dealership for a systems check (which I guess i will need to do). However, i wonder if this isn't related to similar problems i had with our VW golf -- that could mean that it is a software issue or a firmware issue. The VW garage never did find the cause of the fault I had with the Golf.

One reason I changed from the Golf to a Skoda Kamiq was the Golf's problem, but guess what! The problem appeared in the Kamiq as well. And, now in the Born. I'm certainly leaning toward it being a basic software/firmware problem which would permeate the VW ecosphere.

Any suggestions or thoughts?

The key not detected is likely to come up when the remote battery is week so bringing that upfront under the dash area or wherever they say is the fix to that if it's the weak battery one. Mine got me this year in an Irish Ferry queue to get on the boat... lane 1. Would not start. I pulled the key out of my bag on the back seat and stuck it up front. Bought a new battery in Ireland the next day at great expense over Amazon. Some people keep a spare battery on them tucked away I then found out. I've done that now. That was the Ateca. The Arona was the other one. All my problems have been down to weak battery on the Ateca and multiple key working on the Arona where it doesn't take too kindly to swapping keys between lock and unlock with different keys on the touch handle.

They do change the design so might have engineered a gremlins in.

changing the battery on the remote key made no difference to the problem, so i doubt it's the battery.

Wiped the baby bite off them . Duracell ones are coated with baby bite so they don't swallow them. People moan they don't make good contact till it's rubbed off. Other people won't buy Duracell for that reason. Failing that a dealer issue. I stick them across a meter when I taken them out or put them in.

thanks for your suggestions. the battery i currently have is an Energizer and latest info on them is that they do not have such a child-proofing on them.
The issue continues, with intermittent failure to recognise the key as being in the car, even though it it. There is also a delay in recognising the key sometimes, as if the car was 'thinking'/processing information for a few seconds (maybe three) before acting.

So, wondered if perhaps it is a wi-fi receiver issue, rather than a transmitter problem. I don't know how I could tell that, though, so will probably need a check at the service point.

An addition issue that cropped up yesterday was that the Qi charger (which had been active) suddenly stopped and there was a message that the charger was not functioning. Despite best efforts over the day, the Qi charger never did start to charge again.

More glitches in the electronics -- not a good sign for what essentially is an electronic-centric vehicle. :-(

Sounds like you have a list for your dealer to look at. The fully broken things are better rather than intermittent .

before I rant my car does have Kessy ...

But what a waste of technology and effort. I can now save time by not having to press a button!

However I have to keep my key in a Faraday pouch so I have to remove it and replace it each time I go to the car or drive anywhere. The keyfob batteries dont last half as long. Thieves love keyless cars.

Oh but I have a start button!! Whooppiieee Doooo!!

The very reason I got Kessy turned off by the dealer on collection day.

Agree on Kessy (keyless entry / start) being a rather pointless feature (IMHO of course; there’ll be some owners who like it). My VW has keyless entry / start; it was part of the standard spec - if it hadn’t been, I would never have paid extra to have this feature.

It should be possible to either temporarily or permanently disable keyless entry function on your Formentor - screenshot below is from the June 2021 edition of the Formentor owner’s manual. I can’t permanently disable keyless entry on my VW but I can temporarily disable it each time I lock the car, which I always do.

I seem to remember reading somewhere that the latest generation VAG keys go into sleep mode if they’re not moved for a specific period of time - sorry, don’t know where I read it or what that specific time period is, although it should be in the owner’s manual somewhere. If so, then that probably means it would be unnecessary to keep your key fobs in a Faraday pouch.

 

[Cupra306Form]

Thanks SRGTD I'll have a look at the manual. There's actually so much tech that it takes ages to get round to reading up on more after I've grasped the basics!! I will turn it off, it's totally pointless. Far more hassle than pressing a remote. No way would I risk leaving my keys out of it can be stolen easily with a signal booster, so this might be the answer for me.

The new cars have technology to prevent relay theft.. you're wasting your time with a Faraday pouch. (The technology works).

The cars have 4 additional receivers as subsystems on the body control module which monitor the true distance between the vehicle key and the vehicle (atleast in the UK, not all markets have this)

Ah thanks, do you know from which model year that was introduced please? Mine is a 72 plate, so either a 2022 or poss a 2023 MY.

Since launch on all MQBevo vehicles with KESSY (for the UK, unsure on other markets.)

This is taken from the Self Study programme for the A3 8Y but it's applicable to the other brands.

The system measures the distance between the ignition key and the vehicle. This is done by measuring the time a signal takes to travel in the gigahertz frequency.
. The function “Open with convenience key” is only possible and permitted within a defined distance. There is no communication between the key and the vehicle outside the defined area. The technology is called RSAD UWB. This stands for Relay Station Attack Detection via Ultra Wide Band.

At Audi, RSAD modules are referred to as “control units for break-in protection”. These are control units 2 - 5 for break-in protection (J1192 - J1195). They send UWB signals. The distance between the sender and the receiver is determined using the signal travel time and stored in the ignition key.

Put simply, the system measures the time between sending the signal and receiving the response. The time measured is referred to as the time of flight (ToF). If the time measured (a few nanoseconds) is multiplied by the propagation velocity of the radio waves (almost the speed of light), the result is the distance between the vehicle and the key, correct to within a few centimetre

The onboard supply control unit J519 is the central locking system master on the Audi A3 (type 8Y) The entire control system for the central locking functions (including the RSAD control system) is located in the onboard supply control unit.

The entry and start authorisation control unit J518 communicates both with the onboard supply control unit J519 and the four control units for break-in protection J1192 - J1195 via a sub CAN.
J518 also performs the usual tasks:
> Reading in the signals from the capacitive sensors in the door handles
> Activating the entry and start authorisation aerials
> Wake function for the onboard supply control unit J519 via a discrete wire
> Activating the warning lamp for ignition and starter button K267
> Reading in the button signals from entry and start authorisation button E408

The electronics for the UWB technology are only present in the ignition key of vehicles with PR numbers 5F1, 5F4 or 5F8.

However, the UWB distance measurement is not automatically used on these vehicles in all cases. If a vehicle is simply locked with the remote control, no UWB query is made.

On vehicles with UWB distance measurement, the central locking system sends signals in the following frequency ranges:
> If the vehicle is locked or unlocked via the remote control, the key sends its signal in the UHF frequency at either 315 MHz or 433 MHz, depending on the vehicle and country.
> If the central locking system is operated using the convenience key functions, the four aerials (R137, R138, R200, R201) communicate at a frequency of 125 kHz.
> The communication between the four control units for break-in protection and the ignition key takes place in the UWB frequency at either 4 GHz or 6 GHz (frequencies depend on the country).
