Keyless Go fix-apparently
I posted this on a relevant thread for the C class, but figured I'd put it here for the correct model.
It's fixed for now. Had the problem with a new to me (used) car delivery. CLS550 2014. Lots of complicated failures but after reading all this. I changed both batteries. Had to replace 2025's with 2032's. They are both 3V with the bigger number being fatter and longer lasting.
I just went out with one key at a time and unlocked and locked with the remote buttons. Then tried keyless entry and engine start, one key at a time, with the other far off. They both work now, the car says the batteries are low in both keys, so they've ben in my storage for maybe 3 years, so that very well may be true. So I'll change them out and see if that message goes away.
Solution: Wait. Unlock and lock with the key, and then do the handle/keyless entry method and maybe you will be as lucky as I am. For today.
I put the old skinny batteries in just to see, and one of them was dead as hell. So I put the fat battery back in and it works.
