Electronic barrel comprising a barrel body and a rotary-lock key bit, the barrel body comprising at least one rotor having a common axis with the body and the rotary-lock key bit and freely rotating in said body, a clutch part coupled in rotation with the rotor and comprising meshing means co-operation with additional means matching the key bit so as to drive in rotation said key bit by the rotor under the action of a rotating torque of the key, and locking means for preventing the clutch part from being translated when there is no recognition of an identification code transmitted between the key and the barrel, characterised in that said locking means are further mounted integral in the rotary-lock key bit and the rotor is mobile in translation for thrusting the clutch part towards the key bit when said identification code is recognised.
