A park lock system for a shifter of an automatic transmission, according to one embodiment, includes a blocking member pivotal between a locked position to prevent movement of the shifter and an unlocked position for allowing movement of the shifter. At least a portion of the blocking member may include hard magnetic properties, such as having a permanent magnet coupled therewith. An electromagnet may have a core member proximate the magnetic portion of the blocking member to cause the blocking member to move to or remain in the locked position when the electromagnet is de-energized. Accordingly, when the electromagnet is energized, the electromagnet may be configured to generate a magnetic field in repelling polarity to the magnetic portion that causes the blocking member to move to the unlocked position.
