Slide a flat object, such as a flat-head screwdriver or a paint scraper, under one corner of the magnetic kick plate.
Pull the object toward you to break the magnetic seal between the door and the kick plate.
Grasp the corner with one hand that was pulled away when the magnetic seal was broken.
Slide your other hand under the lifted portion of the kick plate.
Slide your hand in the direction toward the side of the kick plate that is still magnetically sealed to the door while prying the kick plate upwards in the same direction with your other hand.
Continue to slide your hand over, breaking the magnetic seal, while pulling the kick plate off with your other hand until the kick plate has been completely detached from the door.
