An electromechanical locking mechanism provides a plug with a rekeyable primary lock mechanism such as a tumbler stack, an electromechanical operator such as a solenoid or a motor, and an electronic circuit having a memory, or an electronic memory and an electronic logic stage, controlling activitiation and operation of the electromechanical operator, contained entirely within the plug. Insertion of a blade of a key that is properly profiled and bitted to correctly displace the primary lock assembly relative to a cylinder encasing the plug, and application by the key of electrical power, or of electrical power and a correct data signal, to the electronic circuit, will cause activation of the electrical operator and repositioning of a distal member of the operator relative to the cylinder, and thereby enable torque manually applied to the blade of the key to rotate the plug within the cylinder.

1. A plug, comprising: a first terminal portion;a second terminal portion separated by an axial length of said plug from said first terminal portion, said second terminal portion disposed to support a cam, said plug being perforated by a plurality of radially oriented apertures forming an array;an exterior surface extending between and engaging said first terminal portion and said second terminal portion;a sidebar positioned between said first terminal portion and said second terminal portion to reciprocate between a first location with said sidebar simultaneously engaging said plug and a cylinder surrounding said plug, and a second location releasing said plug for movement between the cylinder and said plug;at least one locking mechanism disposed within at least one of said apertures to move relative to said plug in response to a key engaging said first terminal portion to accommodate reciprocation of said sidebar relative to said plug and rotation of said plug relative to the cylinder when the key while said first terminal portion engages in a selected relation with said locking mechanism, said locking mechanism obstructing said reciprocation absent said selected relation;an electronic logic circuit borne by said plug, generating control signals in dependence upon electrical power and data signals received from the key; andat least one electrical operator comprised of an electrically conducting coil coaxially disposed around an armature within one of said apertures, said sidebar, said logic circuit and said armature being borne by said plug and rotating with said plug relative to the cylinder, said armature travelling in dependence upon said control signals between a first position relative to said exterior surface obstructing said relative movement by engaging said sidebar, and a second and different position relative to said exterior surface accommodating said relative movement. 2. The plug of claim 1, comprising said sidebar, locking mechanism, logic circuit and electrical operator simultaneously experiencing said rotation relative to the cylinder whenever said plug rotates relative to the cylinder. 3. A lock, comprising: a cylinder containing a hollow recess defining a longitudinal axis and a detent extending from said cylinder;a plug rotatable around said longitudinal axis while resident within said hollow recess, said plug comprising: a terminal portion providing an electrical conductor;a second terminal portion disposed to support a cam;an exterior surface extending between said first terminal portion and said second terminal portion;a sidebar borne by said plug to create an obstruction to relative movement between said cylinder and said plug;a locking device disposed within said plug to release said obstruction when a key engages in a selected relation with said locking device, and to maintain said obstruction absent said selected relation;an electronic logic circuit borne by said plug, coupled to receive electrical data signals via said electrical conductor, and generating control signals in dependence upon said electrical data signals; andan electrical operator borne by said plug, disposed within an aperture, said operator having a distal member traveling along an axis transverse to said longitudinal axis, in dependence upon said control signals between a first position relative to said exterior surface by engaging said detent and thereby obstructing said movement in concert with said locking device and a second and different position relative to said exterior surface accommodating said movement. 4. The plug of claim 3 comprising said sidebar, locking device, logic circuit and electrical operator simultaneously experiencing said rotation relative to the cylinder whenever said plug rotates relative to the cylinder. 5. A lock, comprising: a shell containing a hollow recess defining a longitudinal axis and an interior cylindrical surface;a cylinder plug rotatable around said longitudinal axis while resident within said hollow recess;a bar borne by said shell and interposed between said shell and said cylinder plug to create an obstruction to rotation of said cylinder plug within said recess;said cylinder plug comprising: a first terminal portion and a second terminal portion separated by an axial length of said cylinder plug from said first terminal portion, said second terminal portion configured to support a cam;a logic circuit generating a control signal in response to a comparison between a code set within said logic circuit and a data signal applied to said logic circuit; andan electrical operator comprised of an electrically conducting coil coaxially disposed with an armature borne by said cylinder plug and rotatable together with said cylinder plug, locking mechanism, logic circuit and electrical operator relative to the shell whenever said cylinder plug rotates relative to the shell, said electrical operator being electrically operable to respond to the control signal by moving the armature independently of said bar between a first orientation accommodating relative movement between said shell and said cylinder plug and a second and different orientation maintaining obstruction of said relative movement while the armature engages said bar. 6. A lock, comprising: a shell containing a hollow recess defining a longitudinal axis and an interior cylindrical surface;a cylinder plug rotatable around said longitudinal axis while resident within said hollow recess, said cylinder plug comprising a first base and a second base separated by an axial length of said cylinder plug from said first base, said second base bearing means for supporting a cam;a bar interposed between said shell and said cylinder plug to travel generally along a radial plane between a first position engaging both said shell and said plug while obstructing rotation of said cylinder plug within said recess, and a second position accommodating said rotation;a logic circuit generating a control signal in response to a comparison between a code set within said logic circuit and a data signal applied to said logic circuit;an electrical conductor provided by said plug, conveying said data signal to said logic circuit; andan electrical operator comprising an electrically conducting coil coaxially aligned with an armature, said armature, said bar and said logic circuit being borne by said cylinder plug and rotating around said longitudinal axis with said cylinder plug, said electrical operator being electrically operable to respond to said control signal by moving said armature independently of said travel, between a first orientation providing obstruction of said travel and a second and different orientation accommodating said travel.
