Keyless Go/Entry Occasionally fails
Ever since I bought my 2015 E400 Cab, it's had occasional fits where the keyless go and entry just fails and I have to use the 'old-fashioned' way to enter and start the car. I've never bothered to troubleshoot, as it's been infrequent and it resolves itself after a brief time. My key fob battery is fresh, and the aux battery is still healthy, but has anyone else experienced this or any ideas what's the root cause? I was prepared to troubleshoot today, but everything is working normally now. It's starting to feel like my old Land Rover RRC...

My "touch the handle" to unlock doesn't work now and then, maybe once every 2-3 months. I haven't noticed a pattern.
The Keyless Start button stopped working one day when I was using Xentry. Then I got it working again, only to fail shortly after and never work again. Xentry has always said nothing is wrong with it, btw.
My guess is they just die. Knowing electronics as I do, I'm surprised they last as long as they do.
