Keyless Go (Entry) Issue
I am having intermittent issues with the keyless entry system not working on my 2016 C63. I've changed batteries and changed fobs and still having the issue. Every now and then, it just won't unlock/lock when I am next to the car with key in pocket trying to open the door or lock before walking off. It is infrequent (maybe once out of every 25x) but annoying when it does happen and I have a handful of stuff and now need to dig in pocket for key.
I was just in a shop for an unrelated item and they said there was a TSB on it. I've searched and haven't been able to locate and just called my local dealer who said there wasn't a TSB on that. Has anyone else experienced this issue? I assume it's just every now and then having trouble recognizing that the key is nearby?

Very common issue. Had it on my c43 and now on the 63. The inner door panel needs to be removed to replace the sensor and it takes hours to do all 4 doors. I usually try to use the rear door touch pad when the driver door isn't cooperating.

I located this xentry item but it appears to be about a different fob? At least per the picture and the references to a red LED that I don't believe my fob has.
