How to Unlock the Handle Without a Key on a Toro 1800 Power Curve
- 1). Unplug the Toro's power cord from the wall.
- 2). Use a screwdriver to loosen the screw on the underside of the Power Curve's control panel, beneath where the handle key would normally be inserted. Take out the screw.
- 3). Twist the lever arm mechanism to the right to the "On" position with a pair of pliers. Leave it in this position. This will keep the handle unlocked until a new key can be obtained.
- 4). Replace the plastic panel piece on the bottom and replace the retaining screw with the screwdriver.
