Abstract: An electronic cam lock accessible either by PIN code or wirelessly transmitted code from a user's credential has a compact electronics housing that fits neatly and unobtrusively in office furniture, including metal or wood file cabinets. The housing has a rear-extending driver, which may be within a cylinder, preferably positioned where the driver of a cam lock of conventional keyed configuration would be located. One form of the lock is front-recess mounted. In another form the housing is inside-mounted, fitted within the usually one-inch top rail or vertical side rail of a file cabinet, with the electronic access terminal and a rotatable knob exposed for the user. The locks can be connected in a wired or wireless network for controlling access by time or by personnel, or for auditing entries.

Abstract: A cam lock for cabinets, drawers, drug cabinets, credenzas, sliding doors, lockers, mail boxes and other door type applications is compact in size, fits an existing cam lock opening and provides electronic access via a keypad or other electronic access. Using batteries, such as AAA size batteries or smaller, the lock has electronics that release a lock turn knob or handle when the correct code is entered. Preferably a set of electronic contacts is included at an accessible position on the lock housing to allow both master access and power jumping with a common manager's implement, for situations of lost codes and/or battery failure. In a particular embodiment the lock is long, narrow and low in profile so as to fit on the margin of a steel or wood file cabinet, compatible with the cam lock opening already provided.

Abstract: An electronic lock replaces mechanical locks in cam lock, cabinet lock and switch lock applications, as well as other locks for file cabinets, desk and cabinet drawers, access panels and other secure situations that often utilize relatively simple lock mechanisms. In a preferred embodiment the lock is without a keypad, accessed by an electronic key making contact with a terminal.

Abstract: A locker lock fits a standard locker door three-hole door prep, with all electronics contained in a single housing mounted on the front of the locker door and a latch device behind the locker door. The locker lock preferably includes a keypad to allow rotation of a handle or knob, and also includes a manager's override and power jump terminal.

Abstract: A mechanical key and lock cylinder with mechanical bittings include an electronic access control feature, with minimal modification and without affecting or interfering with the mechanical function of the key and cylinder. A small, low-profile memory cell is embedded in a recess or later hole through the key, with one cell terminal grounded to the key and the other having a contact extension. When the key is inserted into the keyway of the cylinder plug, the ground connection is made with the cylinder and the memory cell contact extension engages a spring-loaded contact of a connector unit which extends from the cylinder plug. An insulated wire carries the conductive path out of the lock cylinder. The key remains of very low profile, and the cylinder plug is modified only by a small longitudinal bore from front to rear. Existing mechanical locks and cylinders can easily be retrofitted with the electronic access control feature.

Abstract: An electronic lock device for lockers of similar uses has an input for a user code (keypad or electronic key reader), and a separate input for a manager key. Contacts at the manager key include power jumper contacts, so that when a user is unable to open his assigned locker, whether this is due to a low battery in the lock or failure of the user's key or the user's forgetting a PIN code, the manager key device will open the lock.

When the key is inserted into the keyway of the cylinder plug, the ground connection is made with the cylinder and the memory cell contact extension engages a contact of a connector unit from the cylinder plug. The key remains of very low profile. In another embodiment the key has its contacts on one or both sides of the key blade rather than at the shoulder of the key head. The memory cell device in or on the key head can include a microprocessor, battery and read/write memory.

Abstract: Locks and keys are disclosed with electromagnetic as well as mechanical actuation. Several forms of reverse sidebar are described, avoiding binding of the lock release mechanism by premature turning of the key by a user. An embodiment of a system is described wherein the lock units are in radio communication with a control console, for setting access parameters and monitoring accessing events at each of the various locks.

Abstract: A system of locker compartments at various locations is controlled by a central system processor. A communication system from the central processor to all locations, and all lockers within a location, enables central control of rewritable locker access codes, reservation of appropriate lockers for delivery of orders, and monitoring of status of all lockers in the system. The assignment of lockers and codes can be web-based, and can be done by a vendor, a delivery company or an online customer.

Abstract: An electronic lock device includes provision for setting different bolt or latch extension lengths, to accommodate different door lock situations. In addition, the bolt or latch itself preferably is interchangeable for bolts or latches of different sizes or configurations, including switching a latch for a bolt or vice versa. The bolt or latch extension can be settable via a keypad or ibutton. In the preferred embodiments the lock units include a D.C. geared micromotor, which is also included in other electronic lock units disclosed.

Abstract: A mechanical lock and key includes an electronic access control feature for preventing opening of the lock unless prescribed conditions are met. The lock cylinder, preferably the cylinder plug, is fitted with a small ID or “serial number” chip which is read when a voltage is applied. A connected addressable switch is connected to a solenoid capable of withdrawing a blocking pin, when the switch is activated. The mechanical key has a key head with a battery, microprocessor and database. When the key is inserted into the lock, a one-wire bus connection sends the lock ID to the key's microprocessor, a comparison is made by the microprocessor to determine whether the lock is authorized to be opened, and if so; a code for the addressable switch, determined from the key database, is sent via the one wire bus to the switch, powering the solenoid, withdrawing the blocking pin and enabling opening of the lock.
