What Does It Mean When Your Key Battery Is Low. This should be done as soon as possible so that your home remains protected. From what I understand the car does not charge the key at all.
When you turn off the engine the battery discharges but keep lights radio heated seats AC or any accessories ON. Also to know is how do you know when your key fob battery is low. The Real Clock RTC battery provides power for the inernal real time clock and calendar.
If your key fob battery went completely dead you wouldnt be able to start the car and could end up stranded somewhere.
It means the battery is one of your remote keyfobs needs replacing. Key battery low the message on the dashboard read. I ignored key battery low alert for about 2 months until the other evening when my smartkey wouldnt work. With an empty RTC battery following message will appear during start-up.
