Just encountered a huge issue last night. I was out running errands and went back to my car, and the door wouldn't unlock. I tried using my key fob and nothing happened. I ended up using the key inside of the fob to get the driver's door open, but the car still would not start. Infotainment system worked fine, AC worked fine, but car did not detect my key and wouldn't move.

I called the dealership, but they told me very nicely to go kick rocks. I tried using the SOS and call buttons in the car above me, but nothing happened. I called Volvo using my phone, and the rep told me to put my key in my cup holder on the key symbol. I told him that there was no key symbol in my cup holder, but he told me to it anyways and shift to drive. Nothing happened, so he put in a tow request for me. after 30 minutes, I finally get a text telling me that the tow truck is 90 minutes away.

I do some research and I find that one way to at least drive the car is to open up the center storage behind the cup holders, and place the key on the key symbol. Doing so and shifting did allow me to start driving, but I got a "sos" popup and a sos symbol on my dash. I still can't lock or unlock the car, but at least I can drive it. I have have a service appointment Monday morning with the dealership to see what the issue is, but I suspect it has something to do with the new update. I've some minor issues with unlocking my car ever since the update, so I'm thinking it broke something.

TImeline of issues:

1. Updated to 2.3 early in the morning.

2. Car would intermittently not automatically unlock and open when I put my hand on the handle, even though I had my key in my pocket. Unlocking manually with the fob would still work, and the car drove fine.

3. Had major issues charging at EA stations. One station didn't detect my car even after getting reset by customer service, and I had to plug and unplug 6+ times at another station before it would correctly start charging. I chalked it up to EA being EA at the time, but I wonder if it was a symptom of the bad update.

4. Late afternoon, car would not unlock automatically. Fob also did not work.

5. I unlocked the car manually using the key inside the fob. Alarm sounded, and it would not turn off no matter what I did. Alarm eventually went off on its own.

6. Going into the system menu, the "Security Update" icon was red with an exclamation mark. Selecting the icon took me to the updates screen which showed no issues and displayed I was on 2.3.

7. Trying to factory reset the car gave an error that stated the there was no communications with telematics. However, the car had 4G service.

8. It would have taken 2 hours to get a tow truck to me using Volvo Care. I'm in the middle of Chicago, so I'm not sure why it would take so long.

9. Dealership was supremely unhelpful as it this after 5 and their service department isn't open on Saturday. I made an appointment on Monday, and they were noncommittal about providing a loaner.

The 2.3 update was taken down because of bugs. You most probably fell victim to them

Taken down? When? Where does it officially state? I haven’t received any communication from Volvo on this? One of the key feature updates 2.3 consisted of is the first item highlighted in bold below.

Updates in software version 2.3

  • Solution to an occasional issue when unlocking the car using a key fob.
  • Minor graphic updates of the trip meter menu in the driver display.
  • Solution to false “Service Required” message related to Parking Assistance.
  • Ready to drive notifications are calibrated to work better when using Pilot Assist.
  • Improved range estimation accuracy, for MY21 and MY22.
  • Drivetrain optimization adjustments, for MY21 and MY22.

Sorry this happened to you. One thing every dealer should tell people about during the pre-delivery walk-though is the manual key blade and how to use it (and check to see if the fob you're using has a manual key blade!), and the key fob position in console to enable emergency reading of the key.

There is a thread regarding the pulling down of the 2.3 update. Even people on other forums are reporting that their car is unable to recognize the key.

To what I can see, it’s only Polestar P2, that has put out the update. What about Volvo’s stance on the C40, XC40? These two are mutually exclusive with different software deployment mechanisms (making an assumption) with a similar vehicle architecture on all three vehicles. Let’s see what Polestars got to say about this in the meanwhile.

I updated to 2.3 about a week ago and just ran into this issue as well. SOS error popped up and car won’t recognize my key.
I’m definitely going to be more slow on the trigger downloading these updates going forward. Anyone know if it’s possible to roll it back to 2.2?

User accessible way I don't think so. Possibly the dealer could downgrade the firmware but I might be mistaken

Honestly the symptoms here sound like the (unfortunately) typical TCAM hang/crash problem that shows up in the XC40 too, and not necessarily anything to do with the update. @c40chi your problems present exactly like mine did back when I was on 2.2.

The solution is a TCAM reset, which is a little bit involved: pull a fuse and disconnect the TCAM backup battery under the rear cargo floor, then connect everything back together. It’s perfectly feasible to do yourself, but like I said, a little involved.

I took pictures when doing mine - which BTW has not recurred and has only happened once in four months. I’ll post a tutorial when I can.

Obviously I can’t promise this is your problem, but it’s easier to try this than to deal with a service appointment in my opinion.

I keep seeing people posting about Volvo support telling them to put the key in the cup holder when it can't be detected properly, when the actual spot for the key is in the storage cubby. It's really aggravating that they would keep giving misinformation to people in a bind and in need of urgent help getting their cars started. How do we let them know they're misinformed?

I had the same experience as Wixoff with my XC40 running v2.2.

Car would not recognize the key -- exact symptoms as described in this thread. Luckily it was sitting in my driveway at the time. I did the TCAM reset by pulling the fuse and disconnecting the backup battery. Problem has not re-occured since.

I did notice that after I did the TCAM reset that whenever I would charge the estimated completion time for the charge would be WAY off. Actual charge time would be normal but the TOD displayed for completion in the drivers display would be crazy -- i.e. charge would take 2 hours but the estimated TOD would be 7 hours later. It was like the TCAM was displaying the time for a different time zone or something. This went away after the v2.3 update. I suspect that this had nothing to do with the new software and is more likely that the update process reset the TCAM and it synchronized to the correct local time after this reset.

Just tell them directly “write to volvo customer support”!.

Update:

Brought my car to the dealer at 8am, and they told me it would take 2 days to fix. I asked about a loaner, and the rep told me loaners are reserved 3 weeks out. Fuck me, I guess. I call Enterprise and to reserve a rental and get picked up from the dealer. The rep sets up a 10:30 reservation and tells me someone will call me before then. I get a call from Enterprise at 10am, and they tell me that they can't pick me up. Apparently, they outsource their reservation customer service, and those reps didn't tell me I was out of their service area and no pick up is available. Keep in mind that the Enterprise is less than 2 miles away. Fuck me again.

I’ve had the same issue and had the same loaner experience (Bay Area, CA). I drove it in that state for weeks until I finally gave up and brought it in. It really is quite sad how bad Volvo’s customer service is. I’ll never buy another Volvo.

I did what you suggested, and it worked like a charm. Key fob works now, and is property detected. Thank you!

I had a little trouble finding the TCAM backup battery, but I found a picture of the location on the XC40 recharge and it was in the same place on the C40. I had to fold both back seats down, open the cargo floor, unclip the clips on each side under the floor so I could lift the entire floor. The TCAM battery is located under the rear driver's side seat (left).

OK, I posted it, but I guess it requires approval by a mod before it will show up. Keep a lookout here in our cozy C40 section.
I actually saw your tutorial post yesterday but when I hit like it said post not found or something. Odd...wonder what the deal is?

Yeah, I don't know what the deal is. I made the post two days ago, and can see it from my profile, but it's crossed out and says "Awaiting approval before being displayed publicly." I don't swear in it or anything!

I think I'll try to PM the mods - it looks like neither of them has logged in for more than a week ("Last Seen: Sep 12, 2022" for both). I think my post will be helpful because it has some new pictures and experiential knowledge that will make the reset process easier for people, and I see this issue come up every few days.
