An electromechanical cylinder lock-key combination includes a cylinder housing and a cylinder core rotatably arranged in the cylinder housing and having a key-way for receiving a key. A plurality of key actuated moveable blocking elements block the rotation of the cylinder core unless a correct key is inserted in the key-way. An optical code reader in the lock reads an optical code element provided on an inserted key. At least one of said blocking elements functions as a bar element barring insertion of the key into the key-way unless a correct optical code element is provided on the key. By using at least one of the mechanical elements already present in the lock as part of the electronically controlled blocking mechanism, in combination with the use of an optical code requiring no moveable parts for the reading thereof, space requirements in the lock device are kept to a minimum.

An optical device includes: a lock having a locking unit and an actuation unit having at least one sensor and a reflective plate; and a key for the lock, configured with an unlocking unit having at least a light-guiding element for transmitting optical signals between the actuation unit and the unlocking unit. The actuation unit is activated to unlock the locking unit after the sensor detects and recognizes the optical signals. As the optical signals that are to be transmitted between the actuation unit and the unlocking unit can not be intercepted easily and also can be encoded, not only it is difficult to forge the key for the optical device of the present invention, but also the structural integrity of the optical device will not deteriorate easily after being used for a period of time. Therefore, the present invention is low in cost and has an excellent anti-theft effect.

The key comprises at least one coding cavity (55) defining a hollow geometry for coding the key. The geometry includes at least one internal undercut (60a, 60b). The lock for validating a key comprises blocking means (21, 22) coupled to a driving part (14) and validating means (25, 26) which are coupled to the blocking means so as to change the state of the blocking means when the key used with the lock has a correct coding. The validating means (25, 26) protrude at least partially into the key cavity of the lock in order to introduce the validating means at least partially into the coding cavity (55) of the key and to sense the inner face of the coding cavity.

A two-dimensionally driven lock and key are provided. The two-dimensionally driven lock has a lock core having sliders and a block. The sliders are movably and rotatably mounted in the lock core. Each slider has a recessed portion and a non-circular positioning portion. The block has protrusion portions selectively received in the recessed portions. The key has positioning dimples identical to the positioning portion in shape. When the key is inserted into the lock core, the positioning portions match to the positioning dimples respectively and the protrusion portions face to the recessed portions. An unlocking method includes inserting a key into a lock core to make the recessed portion and the protrusion portion face and align to each other by moving and rotating the sliders. Therefore, a location of the recessed portion can vary on the slider in two dimensions, and thus making ulocking very difficult.

A light fence represented by aligned apertures in a plurality of wheels permits the passage of a light beam to a sensor to activate an electro-mechanical control for a lock. Such an arrangement avoids the sound-producing mechanical action of the typical tumbler lock and safeguards discovery of the opening combination. Rather than the typical case of a numerical sequencing combination, a novel approach is taken by using visual pattern recognition to align the apertures. The electro-mechanical control of the present invention additionally features optimized energy use, customizable settings, precision positioning, and an expansion of possible combination permutations by including direction of rotation.

A smart entry system that releases a lock of an opening / closing body includes: a transmission unit that transmits a call signal to a mobile key by wireless communication; a reception unit that receives a response signal from the mobile key responding to the call signal; and a control unit that outputs a call signal transmission command to the transmission unit, performs authentication of the response signal when the reception unit receives the response signal, and outputs a command for unlocking the opening / closing body based on a result of the authentication. The call signal is transmitted by a polling system. The control unit includes an output strength setting unit that changes and sets an output strength of the call signal.
