Key Fob issue

[RenGentMan]

My 2018 Sport Key Fobs have slowly diminishing functionality. They used to give me a Low Battery Indications, replaced batteries on both Fobs several times, then over the last several months, neither will now start the car without pushing Fobs into the Start Button, but still at least locked and unlocked the car, but now won't even do that that, locked the car manually and then won't respond to any input at all. Anybody else have this issue?

Yeah, this is a known headache on these cars. It's almost never the fob batteries. The battery in the car, the one under the hood, is probably dying. Even if it tests okay, a weak car battery messes up the key fob communication first.

Get your car's main battery tested and most likely replaced. That fixes it 9 times out of 10.

Many thanks for the suggestion, I will do it today before I get locked out again!

There's no battery under the hood of the G80!
