The invention relates to a key (1) for an electromechanical locking device (101), having a key bow (2), with the key bow (2) comprising a light device (75), and with the key bow (2) comprising electronics (70) which are designed to actuate the light device (75) to reproduce at least one item of information in a luminous manner.

An unlocking system including an elevator system with a lock having an unlocking mechanism and a keyway, the lock configured to secure a door of the elevator system and a detection device configured proximal to the keyway, the detection device configured to detect the presence of an authorization device configured to operate with the detection device that is located in proximity to the unlocking mechanism. If the detection device detects a key without an authorization device, the unlocking mechanism is configured to be disabled and may not be unlocked. If the detection device detects a key having an authorization device, the unlocking mechanism is enabled and the lock may be unlocked.

This invention permits (or rejects) access to a secure location by authenticating precision up to 106 i.e. 10 to the power 6 or 1,000,000. Such precision allows highly secure and controlled access thereby paving a new field of finer control and security than the conventional security techniques based on software or hardware. Objective of this invention is to provide an additional high-robust-security wall over existing locks/vaults/security systems. Such new high-robust-security wall will allow existing owners, companies to have a hacker-proof and secure mechanism without upgrading or replacing their existing security systems in place. Another benefit of this objective is to launch new industrial sectors as below: 1. Sector (R&D Firms): Manufacture, Test and Create new alloys based on resonance frequencies needed to identify a unique key. 2. Sector (Manufactures): Mass produce such keys and metal plates for each metal once such frequencies are identified. 3. Sector (Maintenance & Support): Highly specialized Maintenance and Support services for customers utilizing this security mechanism. For example, Support services such as, customer might need help for delivering such keys securely, replace existing keys in event of malfunction of the old key, Support key and metal plate manufacturers by regularly providing updates on new alloys designed by R&D firms. 4. Sector (Private networks): Private networks connecting R&D firms and Manufacturers, and another private network connecting Manufacturers and Maintenance & Support, and another network connecting Maintenance & Support services and existing customers.

A locking key for changing a locked state by being inserted into a key box includes a first base including a metal complex and in which a first pattern groove is formed, and a first pattern provided in the first pattern groove and including a conductive material.

Provided is a locking device that allows a plurality of cylinder locks having different security levels to be locked and unlocked with the same unlocking key. A locking device comprising: a cylinder lock having an outer cylinder, and an inner cylinder that is rotatably fit with the outer cylinder; and an unlocking key corresponding to a key hole formed in the inner cylinder, wherein a projecting part is formed at the back end of the key hole, and a positioning recess part that can be fit with the projecting part is formed at the front end of the unlocking key.

A lock device including a keyway sized and configured to receive a key, a sensor assembly including an optical source and a key height sensor, and a controller in communication with the sensor assembly. The optical source is configured to generate an optical signal, and the key height sensor is configured to generate a key height signal in response to receiving the optical signal. The key is configured to interact with the optical signal such that the key height signal varies based upon the height of the key. The controller is configured to generate a key profile based at least in part upon the key height signal, to compare the key profile to authorization data, to select an action based upon the comparing, and to perform the action.

An exemplary system includes a mechanical key and an access control device. The access control device includes a housing defining a keyway that has a fixed position within the housing. The access control device further includes a root depth sensor assembly, an insertion depth sensor assembly, a control assembly in communication with the sensor assemblies, and an electronic lock device. The control assembly is configured to determine the bitting code of the mechanical key based upon information received from the sensor assemblies, to compare the bitting code of the mechanical key to a lock/unlock bitting code; and to transmit a lock/unlock command in response to the bitting code matching the lock/unlock bitting code. The electronic lock device is configured to transition between a locked state and an unlocked state in response to receiving the lock/unlock command and without requiring rotation of the mechanical key.

An electromechanical lock assembly (1) comprising a lock body (13), a lock core (21) located at least partially within the lock body (13) and selectively rotatable with respect to the lock body (13), the lock core (21) including a key receptacle (23), a bolt operating member rotationally secured to the lock core (21) and configured to move a lock bolt of a lock (3) for locking and unlocking said lock (3), and a programmable key (12), wherein said electromechanical lock assembly is configured to be powered upon insertion of the programmable key (12) in said key receptacle (23). A position sensing device (27) is arranged to transmit position data to said programmable key (12).

Pin tumbler locks are provided that include features for detecting tampering. Tampering may be detected in a number of different ways. As an example, abnormal movement of one or more of the driver pins in a pin tumbler lock can be an indication of tampering. In addition, one or more sensors can be included at the end of a keyway that detect picking or bumping beyond the length of normal key insertion. An electrical sensor can be used for detection.

An arrangement and a method for an electromagnetic padlock (10) are disclosed. A handheld unit (30), which is movably connected via a connector member to a lock fitting (50) to be locked by a padlock (10), is removably attached to a padlock (10) during unlocking and locking. When the padlock (10) is locked, a magnetic sensor (44) of the electronic key (40) detects a change in detected magnetic flux from the attached magnet (31), representing a verification that the padlock has both been locked and locked at a correct location. Incorrect locking procedure, or locking at incorrect locations may generate warnings.
