    Security Backup Battery/ Red Flashing Light

    Is there a backup Security battery on a 2012 Mazda 6?
    If so does anyone have a part number or location of the battery.
    I read on a different site that when the backup security battery goes bad the red light (Car symbol with a lock starts flashing on the dash) flashes when the car is turned off.
    My car starts fine, but there is the red flashing light when it's parked.

    Thank You

    The red flashing light while parked is just indicating that the theft deterrent system is active

    Should be in your Owner's Manual
