A key-actuated padlock comprises a shackle, a case to receive the shackle and a flat, substantially U-shaped spring within the case. One leg of the spring serves as a bolt to restrain the movement of the shackle and the other leg serves as an ejector, urging the shackle out of engagement with the bolt leg. The bolt leg is formed to receive a key to unlock the padlock.
