Hello,
I have a DS7 E-Tense 4x4 2020 300HP, Rivoli pack.
I’ve a question regarding the key fob, how much range do you have for lock unlock?
Because I need to be at maximum of 4 meters away from the car for the key unlock/lock to work.
I’ve tried already to change the battery and i don’t have any key case.
Keyless function is working ok. No problem on that.
Anyone else had this issue? Thanks!
Welcome to the community, @Mare_Manica !
4 meters doesn’t sound alright.
I haven’t done any extensive tests really, but 40-50 meters are no problem for me.
I have the same 2020 DS7 300 E-tense.
Does both of your fobs get the same result?
Hello, thanks for info and welcoming!
yes both fobs are having the same problem. I think it’s a receiver problem on the car, but i don’t know how much it would cost (or how should i search for it).
It is funny because sometimes is working (but hardly working) if i throw my hand around or put it to my head (maybe i’m like an anthena haha).
I think you’re right, it certainly sounds like a receiver problem.
Well, putting it to your head is not as crazy as it sounds. It’s actually a known fact that your body acts like an antenna if you do. (https://www.carthrottle.com/news/science-behind-why-your-head-can-boost-car-key-fob-signal)
I have no idea what the cost would be to have the receiver replaced. However, if it were me, I’d probably leave it as is if it’s expensive because I use the keyless all the time anyway.
The receiver has been changed twice on my DS 4 E Tense in the last 9 months.
Technician commented it’s a know issue, with no fix apart from having it changed, luckily my car is still under warranty, apparently they are not cheap to change ?
I’m finding if I press the fob buttons it works from a good distance, but if I use the keyless entry feature I have to be almost at the door for it to open.
Check the condition of the small 12V battery in the armrest. It’s responsible for this function.
Checking the battery at the engine bay wouldn’t hurt either.
If they’re not charged, these could be the symptoms.
I’m in a bit of a debate with DS regarding the 12v batteries.
The main one under the bonnet has been changed 4 times, the one inside (under the arm rest) has been changed once.
I’m currently waiting for the car to go in for its first service, they’ll be checking the batteries again to see if they’re holding out or still depleting.
The main one was changed about 3 weeks ago (4th replacement), the smaller one a few months ago (2nd replacement).
My local dealership are finding that their testing equipment is seeing the battery health on the main battery as failing every time they test it, but I’m not having any errors, or starting issues ect.
I just find it a bit odd that they find a fault but I don’t see any issues ?
How would you go about testing the main one ?
I bought a tester but if I’m honest I’m not sure if the tester is :
A: Faulty
B: Not compatible to test a 12v battery that’s still fitted to the car (even though I can select, "In the Car " & “Out Of The car”, plus I can select battery type, amps ect ect.
OR
C: I’m just not doing it right ?
I always test by using the earthing bond on the cars body and the positive terminal with the battery in the car as I don’t really fancy taking the battery out or fully disconnecting it from the car..
Right now, the most important parameter for me is the internal resistance of the 12V battery. This gives me information about the current battery condition.
I don’t have the same problems as you, so it’s hard to offer any advice.
In my post, I just wanted to point out that the condition of the 12V battery also affects car opening.
Hello again, sorry for very long waiting time, i just got used to it in the end.
Thanks however for your time writing all!
I was wondering lately if is any chance of measuring on my own the trunk battery? Maybe this is the case of having this small range though.
Also you saying that we have 3 batteries? I don’t know about any under the armrest.
So for me there are: 1 on the engine side, 1 on the trunk
It’s worth knowing whether this problem occurs always and everywhere, or only locally?
Hmm sometimes is working from like more 2 3 meters. But nothing more or somewhere else no
Yes, but after the vehicle has been sitting for a while (12–24 hours), you need to open the trunk and wait about an hour. A voltage below 12.3V indicates an undercharged battery; anything below 12.1V means it is discharged.
In general, this battery needs to be replaced every 2 to, at most, 3 years.
Ok, can i do that with my own multimeter? And where exactly because i’ve opened the trunk and that … lid? And i see some electrical wires but nothing like some + or - to put the multimeter on haha
You can do this using your own multimeter, provided it is in good working order and gives accurate readings.
On the 12V battery, the red plastic cover indicates the positive (+) terminal, and the black one indicates the negative (-) terminal. The actual terminals are located underneath these plastic covers.
In any case, the polarity doesn’t matter when measuring voltage; at most, the result might show a negative value, but the magnitude itself will still be correct.
I’m not talking about the front engine one. On the back in the trunk first you have that big cover, then a smaller one with some small handles, and beyond that where you have like the key for wheels, on right side you have a cover. Beyond that i thought it should be the baterry, but i cannot see any terminals
Neither do I.
I’ll look again but nothing that seem like terminals were spoted :d
