Prius Prime Keyfob Battery - Will not respond in cold weather

I have made some observations about my own Prius Prime issues in cold weather and wanted to share these with other owners. I am not going to claim everyone else will have the same experiences. I only want to share my own experiences:

1) My car has the feature where you can lock and unlock the doors simply by putting your hand inside one of the front car door handles. In temperatures lower than 23-degrees, these door sensors will NOT function if the key fob battery is less than 90% of power. You can use the buttons on the key fob to unlock the doors, providing the key fob battery is above 70%. In cold weather (Temps below freezing), the key fob batteries will only last 2-6 weeks, depending on where you store the key fob (the colder the temps, the shorter the battery life). Always keep a pack of brand new key fob batteries available for these really cold mornings or you could be stranded.

2) If the keyfob battery is below 70% of it's power, and the outside temperature is below 30-degrees, the car will often not sense the presence of the key fob inside the car. The simple solution in these cases has been to remove the keyfob battery for 10-seconds, then put it back in. After about 30-seconds the car will start. Another option is to put a brand new battery in the keyfob and it again becomes reliable for another 2-6 weeks in cold weather.

I guess the cost of the key fob batteries has to be included in the overall cost, operation and eco-friendliness of the vehicle.

In stormy, snowy weather, I have to turn off all of the outside driving and parking sensors. Otherwise my dashboard gets lit up, and constantly dings with repeated warnings about sensors not being available.

In hindsight, I do not believe this is the best vehicle to own in these extreme weather conditions where temperatures fall below freezing for a large percent of the year.
