Good day,

Please advise if there is a chronic problem or does my car have a problem?
After starting the car I am advised to change the battery in the key.
I have changed it twice (new battery) and yet it still suggests I change the battery.
Does something require re-setting? I cannot find anything in manual.

Regards,

The problem would be unique to your key and car; it has not been reported as a recurring problem.
