The invention relates to a device (23) for actuating the locking mechanism of a lock, more particularly a furniture lock, said device comprised of a fixing unit (1) by means of which the device (23) can be fastened to a component, more particularly a door and/or window sash, at which the lock is also arranged, and comprised of a handle (27) which is pivoting mounted about a rotary axis at the fixing unit (1) and through the rotation of which the locking mechanism can be manually actuated, and comprised of a power transmission unit (8) which can be torque-proof coupled to the handle (27) to transmit the power applied on rotating the handle (27) to the locking mechanism, wherein the power transmission unit (8) is not coupled torque-proof to the handle (27) until a release code is entered and authenticated, and wherein the entry of the release code is effected by way of electronically picking-up at least one position of the handle (27) relative to the power transmission unit (8), and wherein the entry of the release code is accomplished by electronically picking-up of at least one position of the handle (27) relative to the power transmission unit (8), and wherein the device is comprised of a coupling mechanism through which the power transmission unit (8) can be torque-proof coupled optionally to the fixing unit (1) or to the handle (27).
