Shift lock in a 2005 Mazda 6?

The shift lock in a 2005 Mazda 6 is a safety feature that prevents the transmission from shifting out of Park without pressing the brake pedal. If you are unable to shift out of Park, check if the brake pedal is fully depressed, as the shift interlock system requires it to be engaged. If the issue persists, there may be a problem with the brake switch or the shift lock mechanism itself. In such cases, consulting the owner's manual or a professional mechanic is advisable.
