I recently installed a front & rear dashcam (FitcamX) on my 2022 E450 Wagon.When the front camera was installed without the rear camera, all was well with the world. When I finally got the rear camera cable run, the keyless go intermittently stopped locking / unlocking or starting the car. I can usually unlock the car with the buttons on the fob, and I am instructed to put the key fob in the marked spot in the cup holder to start the car. When I unplug the rear camera, everything works, plug it back in and you don't know if it is going to work or not. Sometimes yes, sometimes no, sometimes one or the other works, sometimes nothing does. When the car and dashcams go to "sleep", I have a better chance to get into the car, but then everything powers up and it becomes a crap shoot whether the car will start with the fob in my pocket.
The rear camera wire runs along the passenger side of the car next to the headliner, through the grommet and into the tailgate. This sounds like interference between the energized cable and the antenna system for the keyless go, perhaps the cable is inadequately shielded, but the cable is too short to be run along the door sills and back up into the tailgate.
I would prefer to keep the rear camera, but if I have to make a choice, the camera goes, I hope it doesn't come down to that.
Does anyone in the group have a suggestion or two?
You could try pulling the cable from the current route and temporarily run it in the middle of the cabin across the seats to see if it is the cable somehow interfering.
Where do you have the power taped for the camera? Is it possible with the added camera you are overloading a power circuit?
The power comes from the front camera though the cable, but, I do not think that is a power problem. I think it it\s an interference problem. I would agree that running the cable directly might solve the issue, my wife would not agree with that fix as an acceptable outcome since it would infringe on her space. It would also be ugly.
Does anyone have any idea where the keyless go antennas are? And how I can avoid them? Maybe ideas how i could increase shielding? If indeed that is the problem

Running the cable directly is not a solution, but rather a test. If the problem persists after doing that then it's not likely an interference issue. If it goes away, then rerouting the cable may be the solution provided you can find an alternate route. Maybe you can get a longer cable.
My question about power is specifically the front camera. All dual camera setups have one camera, typically the front, provide power to the second camera. When adding the second camera the draw from the first camera will increase. It's a long shot and I doubt it's the issue but it's another thing to look at. If the front camera is drawing power away from the keyless go circuit, it could create unexpected behavior. Ideally, you tapped into an auxiliary power circuit aka the cigarette lighter port. Or another power only circuit and not something that has some critical functionality.

I have this same problem before with a Papago unit purchased from Staples back in 2017. I ended up just buying a second dashcam for the rear as well.
It is better that way, as if something happens to the front one and for any reason stops recording, you have the rear seperate and might still be recording so you don't lose both footage. I use a Blackvue in the front and Thinkware in the rear now.
As for the power test. Good suggestion. Could try using a dashcam battery first and not use the 12V connection to see if there is still any interference.
A friend suggested putting a ferrite choke on the cable to reduce interference, will let you all know if that works.
Wouldn't that reduce interference on the cable with the choke which is the camera? Not sure it will help the keyless go from getting interference from the camera. Have you verified it's interference from the cable?
Yes, before the wire was tucked away I ran it to the rear to see how the image looked. Had no problem at that time, only after the wire was in its final position,

I wonder why the camera cable is not shielded which should prevent most interference. Is it possible you punctured the outer jacket when installing it. Have you pulled it out and inspected it for any damage?
I don't think that the cable was damaged at all, perhaps just not up to USA standards? in order to lose the shielding, it would have to be pretty substantial damage to the wire.
Thank you for this post. I've had issues with my keyless go in a 2021 E350 sedan. The issues started when I installed the dash cam, but I never thought of the back camera wire being the issue. Something to look into!
I added two Ferrite Chokes to the rear camera wire, one at the front and one next to the camera. Guess what? Keyless Go is now back to working 100%!
I bought them on Amazon, search Ferrite Ring Core, I got 20 in 4 different sizes for $7.99.
I have 18 more if anyone else needs some.
Really glad to have this behind me!
Picture of the rear cam with the choke on the wire. Almost looks like it came that way.

I'm glad you got it working. I didn't expect those to work but the proof is in the pudding as they say. Maybe they prevent the cable from leaking a signal that inteferes with the keyless signal. Hopefully this will help others with similar issues.

yes, most radio stations have terrible reception when the camera is connected
it's not a big deal as i hardly listen to the radio (and if i do it's via an app) but if this solves it cheaply then why not...

I understand what you mean now. Yes I get those too, worth a shot.
Adding two Ferrite Chokes, one at each end of the back camera seems to have solved my keyless go issues. 3 days without issue after having trouble almost every drive. Kudos to all contributing to this thread!
Really glad this worked for you as well, my Keyless Go has been working since I put the chokes on a week ago. I had one time where the car wouldn't lock or start, but it was right under an intersection of power distribution lines, I wonder if that had anything to do with it.
