A key for an electromechanical locking device,

• wherein a longitudinal axis, a width axis and a thickness axis are defined perpendicular to each other,
• with a key bow and
• with a key shank projecting along the longitudinal axis from the key bow for insertion into the locking device,
• wherein the key bow comprises an electrical energy storage device and/or electronics,
• wherein the key bow comprises a frame in which the energy storage device and/or the electronics is received,
• wherein the frame is rigidly connected to the key shank,
• and wherein the frame comprises at least one grip region which forms a top surface of the key bow for a user to grasp, wherein the key shank comprises a key shank main body, wherein the frame is monolithically connected to the key shank main body, wherein the key bow comprises a housing, wherein the housing is received by the frame, and wherein the housing forms a top surface of the key bow at opposing broad sides intersected by the thickness axis, wherein the frame extends around the thickness axis and wherein the frame forms a free space open on both sides for the arrangement of a housing.
