Key Fob not Working/Engine not Stopping

I’m looking for some suggestions regarding an issue that has recently started with my 2022 DS4 E-Tense.

The keyless entry has stopped working completely. The welcome lights still activate when I approach the car, but the doors don’t unlock. Even pressing the unlock button on the key repeatedly does nothing. I have to press the door handle itself and then keep pressing the unlock button—sometimes several times—before the car finally opens.

I’ve tried my second key and it has exactly the same problem.

More worrying still, on three separate occasions the engine has refused to switch off when I press the stop button inside the cabin. A message appears saying something along the lines of “cannot stop as key not present” even though the key is in my pocket. The engine does eventually stop after repeated tries.

Any thoughts on what the issue might be would be greatly appreciated. I’m planning to replace the batteries in both keys, but I’m not convinced that’s the solution as it seems unlikely that both keys would fail in the same way at the same time. This makes me think the problem might lie with the car rather than the key(s).

Sounds to me as if the receiver in the car is not detecting the fob.

I own a 2023 E Tense DS4 , I’ve had issues with the keyless entry & welcome lights from day one when I bought it new last year.
So far my car has had two new sets of keys, a new receiver, countless updates and some sort of module.
Also 4 new main 12v batteries and a new smaller 12v that sits inside the car.

The issues I was seeing are :
Walk up to the car the welcome lights may or may not come on.
The locks may or may not open.
Walk away from the car, the see me home lights may or may not come on, it did not matter if it was night or day.

The cars alarm would not arm itself when walking away, it would give two beeps indicating what I thought was the doors were locked AND the alarm being armed.
I have since found out that this is NOT how the alarm system works on pre 2024 models.
The two beeps only indicate the doors are locked.
You set the alarm by locking with fob, this is indicated by the two beeps PLUS the side indicators flashing.
You dont see the side indicators flash if just walking away and hearing the two beeps for the locks.
2024 onwards the the alarm is auto activated when walking away, no press of the fob is required.
it took nearly a year of back and fore the service department for them to clarify how the alarm functions on pre 2024 models.

They still cannot work out why the keyless entry and welcome lights are intermittent.

Theres a case still open with DS to try and find a resolution.
However, I’ve a sneaky suspicion theres not actually a fault.
I was reporting a fault because I was only going on how the DS manual said these functions should operate, however after doing lots of research, speaking with other owners and talking in depth with DS master technician from different dealerships they suggested that I look at a Vauxhall manual for a PHEV, my DS operates EXACTLY as the keyless entry & welcome lights do on a pre 2024 Vauxhall.
Bearing in mind the DS, Vauxhall, Peugeot all run on the same platform.
The DS manual is very vague on some instructions .
My son also has a Vauxhall Astra 2022 PHEV, both his car and my DS operate exactly as his manual says.

With yours though theres clearly a fob/receiver issue on the central locking if approaching turns on the welcome lights but not open the locks.

Are checking to see if its all doors ?
Only asking because you can change the settings for all doors to open or just the drivers door.
Also I’ve never seen the message key not present.
Obviously the car isnt seeing the key.
Certainly try new fob batteries first.

Sorry for the long reply but I’ve been dealing with this exact issue for over 12 months.

Thanks for your thoughts Jactac, I’d read in previous posts that you’d had endless problems with a similar issue :disappointed_face:

When you say that your “DS operates EXACTLY as the keyless entry & welcome lights do on a pre 2024 Vauxhall” what exactly do you mean as you’d earlier said, and I’m definitely paraphrasing a little here!, that the operation of your welcome lights and keyless entry is very hit and miss?

I have now bought and fitted a new battery for one of the key fobs and it does seem to have made a difference with the keyless entry working again as I approach the car, but it’s obviously early days and time will tell! I’ve not actually driven since the battery change but hopefully the issue of the engine not stopping because the key is ‘not present’ when it is will also have been resolved.

All the above said though, I’m still open to ideas as to what’s going on as the battery change might not actually be the solution it currently appears to be!!!

You can turn off the engine by holding the start button for a longer period of time.

If both keys don’t work after replacing the batteries, only reading the error codes will help. Does the passenger side keyless entry work as well?

:+1:t2:

Hi Andrew - when things weren’t working none of the four doors or the boot would open ‘keylessly’. However, post key fob battery change and for the time being, they once again are. Hopefully that continues to be the case :crossed_fingers:

Hi,
Had the exact same issue last Friday.
My car stopped communicating with the fob, almost all functions was gone
Pressing “lock” it did something, sounded like the Central locking engaging and disengaging.
Boot was able to be opened.
Display showed “no key present” even though I held it in my hand…
Anyway - theres a spot on the steering wheel column with a symbol like the RFID symbol. If you hold your fob against that symbol you can start and stop the car even without battery in it.

I replaced my battery without any success. After that I disconnected the two batteries, let it sit 10 minutes and reconnected.
After that everything started working again.

As a side not - when this happened I was parked beside a Volvo XC60, I know that Ive had trouble withe the keyless before when parked beside the same car. I wonder if theres some overlap in frequencys or something similar that makes the DS behave like this…?

So I’ll try to explain it as easy as possible.

DS manual says something like.
On approach the welcome lights come on in zone C then the locks open in zone B.
Which mine does but a lot of this depends on how long the car has sat undriven, or if the car has been approached with fob in hand but the doors not physically opened.
The system shuts down these features if certain parameters havent been met.
The manual doesnt explain it very clear.

Example.
The DS manual doesnt explain that the alarm is only set by using the fob to lock the doors.
It doesnt explain that the two beeps only indicate the locking of the doors.
I would wager that many owners think the alarm is set when they walk away and hear the two beeps, but on pre 2024 models the alarm is only set if you use the fob to lock the car.

If you walk away without using the fob you’ll hear two beeps and the doors lock, and thats it, but if you press the lock button on the fob BEFORE walking away and you’ll notice the indicators flash at the same time as the two beeps.
The flashing of the indicators is the signal that the alarm is now active.
If you press the lock button AFTER walking away you’ll see the indicators flash but this hasnt set the alarm, it’s the “find me” feature that flashes the indicators for you to find your car, in a dimly lit area.
None of this is clearly explained in the DS manual.

The Vauxhall manual explains it in detail.

Another thing to look for is if you lock using the remote, BEFORE walking away, you’ll see the full set of lights come on when you later approach the car, not just the DLR lights, if you dont lock using the fob, the next time you approach you’ll only see the DLR’s light up.

By full set I mean the DLR’s , the DS logo mirror puddle lights, and the full matrix headlights with the little pink leds, all doing the fancy dance thing.

Again this is all explained in the Vauxhall manual, it’s not in the DS manual.
Well, when I say it’s not, it’s actually sort of explained but doesnt make clear that it’s year of manufacturer dependant how they all operate.
The thing is these two features, apparently the keyless entry & welcome lights both slightly changed how they operate from 2024 onwards.
Pre 2024 the features a mix of being activated manually with the fob and part automatic when walking away, 2024 onwards, walking away set everything.

The thing that threw me was my car was purchased and registered in 2024, but it was in fact a late 2023 build model, so that threw me when I was looking at how the features should operate, it also didnt register with my local dealership so they kept thinking the car wasnt operating as it should for a 2024 car.
A “new” car could be sitting in stock for 12 months, so if features are altered on they operate on later build cars it can lead to misinformation on cars built earlier but registered later.

Thats what my dealership has now told me, along with DS UK Technical.

The manual for my sons 2022 Astra PHEV, is so clear in explaining it all, so I looked at that and found the two features on my DS 4 E Tense worked exactly per the Vauxhall manual.

If you had the two manuals side by side, you could follow the Vauxhall manual easily and see how these two features work, but if you tried following the DS manual for the same two features , it falls short of explaining it correctly but also gives you the sense that something isnt working correctly because of the way it explains the features.

One minor point - unlikely, but just in case - my previous car started to get inconsistent remote locking behaviour even after changing the batteries several times. It turned out that the supermarket brand batteries, even though brand new and not really cheap, just were not good enough - and swapping to new Duracell fixed it.

It’s worth knowing the car’s production date, as this increases the likelihood that the manual will be accurate for a specific vehicle. This doesn’t mean, of course, that it’s clearly written.
Unfortunately, even in the available sources, DS described it incorrectly, which may be misleading if the car was standing in the DS yard for i.e. 12 months.

Thank you for this Fredrik, it sounds a promising way out of the problem if the stop issue raises its head again :+1:t2: …..would you be able to post a photo of the RFID like symbol on the wheel column you speak of as I’m not exactly sure what you mean? No problem if you aren’t able to.

I’m guessing you mean the two car batteries - again, are you able to give detail/provide photos of how you do this? As above, no biggie if you aren’t able to as hopefully it’s a bridge I’ll not need to cross! :crossed_fingers:

Thanks again Fredrik.

Thank you Andrew :+1:t2:

Disconnecting batteries.

  1. E-tense has two batteries, one under the hood and on in the armrest
  2. Always remove the negative of the armrest battery first. Open armrest, remove rubbermat, press the four clips and remove the lid by placing a finger in the dedicated hole. In the end of the now visible rectangular connector theres a purple lever that you push out in the direction from the connector. Remove the connector from battery negative and let it rest on the side.
  3. Car is still “alive” as the batteries are connected in parallel.
  4. Open bonnet, locate battery on the right side. On positive pole theres a connector with a red lid (+). Flip the lid open levering it from the left side towards the right. When lid is somewhere near vertical the connector should be easily removed by lifting it straight up. I always place something isolating between the connector and battery, the rubber mat that was removed from the armrest works as a sufficient isolator.
  5. Wait 5-10 minutes
  6. Reconnect by doing everything in reverse, start with the positive under bonnet (will spark as theres some current draw immediately when its connected).

Thats about it :slight_smile:

Good instructions.
Have you ever charged your 12v batteries ?
If so do you disconnect them or trickle charge whilst still connected to the car ?

Brilliant, thanks once again Fredrik :+1:t2:

Never charged the 12V batteries in this car. They were replaced maybe half a year ago.
Disconnecting them when charging might mess with the battery management module?

Yeah, my dealership gave me conflicting views on this.
One technician said trickle charging whilst connected is fine, he even suggested what charger to buy, another said to disconnect first, a third said never charge the 12v batteries whether in or out of the car, he said they get some charge from the traction battery when that gets charge and the rest when the engine is running, so there shouldnt be a need to trickle charge.
If he’s correct, in theory if the traction battery is charged just once per week the 12v batteries are also getting a charge.

Also read that the 12V battery gets charged by the traction battery charger. Dont know where i read it or if its true?
My car is always used at a minimum 2x43km per day and some more in the weekends.
Also charging at work 98% of the work days, would be surprised if my batteries had low charge :slight_smile:

Now it’s standing at the workshop again and apparently they wont look at it until the 27th.
Will contact the CEO/Owner and ask him why no one replies to my request of them taking my car back…

My 12v batteries have been changed 4 times under warranty, the last time was a few months ago, so far all is ok :roll_eyes:

Similar issue, I found mine worked so long as you approach, get in and drive. Sometimes the handle needed pressing to unlock but it usually would. Previously its had the batteries replaced along with the ‘receiver’.
I booked the car in for other warranty work and they decided to go back to the keyless problems, two weeks now waiting for ‘a new computer’. Meanwhile the problems it was booked in for have not been looked at. I intend pulling the 2 attempts at repair card!
Oh yeah and the brand new 208 courtesy car is riddled with faults too.
