Abstract: An energy storage device and electrical component are secured under an access cover by a lock. A handle has a key portion that operates the lock. Removal of the handle from an electrical disconnect isolates the component electrically from the energy storage device. The lock is located such that the handle is removed from the disconnect to operate the lock.

Abstract: An electronic key for wireless operation of a lock, in particular motor vehicle lock, with a housing shell (12) for at least partially accommodating circuit electronics for wireless operation of the lock, wherein the housing shell (12) has a battery compartment (14) for accommodating a battery for supplying power to the circuit electronics, a battery compartment cover (16) for covering the battery accommodated in the battery compartment (14), an emergency key (24) which has a key stem (26) insertable into the housing shell (12) and is intended for mechanical operation of the lock, wherein the key stem (26) is movable between an insertion position, in which the key stem (26) is fitted on a key shaft (30) of the housing shell (12), and an end position in which the key stem (26) is securely accommodated in the key shaft (30), and a seal (22) which is arranged between the housing shell (12) and the battery compartment cover (16) and is intended for protecting the battery against environmental influences, wherein

Abstract: Provided is an electronic lock which achieves improved productivity while maintaining the performance of waterproofness for an internal electronic circuit of an insertion portion for a mechanical lock. Specifically provided is an electronic lock provided with a portable machine (1) which contains an electric circuit that locks and/or unlocks a door by communicating with the outside wirelessly, and a mechanical lock which is attachable to and detachable from the portable machine (1) and mechanically locks and/or unlocks the door.

Abstract: The invention relates to a motor-vehicle key, comprising a key housing (2, 3), in which an emergency key (5) is stored. The key housing (2, 3) has a cover shell (2) and a divided base shell (3) which is configured as two base-shell sections (3a, 3b). The emergency key (5) is fixed to one of the base-shell sections (3a) by its key head (7), whilst the other base-shell section (3b) has a shaft recess (8) for the key shaft (9).

Abstract: A bitted substantially rigid extension adapter is provided which may be applied to an existing operating key thereby forming a control key assembly. The extension adapter is provided with fasteners for secure attachment to an operating key. The extension adapter may be made of metal. The bitted portion of the adapter may activate one or more control tumblers in a removable locking core housed within a locking mechanism. The adapter and key, when combined, may be used to remove the locking core from the mechanism.

Abstract: The invention comprises a two part key which replaces a conventional key in a conventional lock cylinder for purpose of temporary use wherein one of the parts is a plastic or similar material insert which replaces a portion of the conventional key and a short conplementary key which permits operation of the lock in conjunction with the insert. The insert being secured in the cylinder by means of the cylinder locking pins and being removable only by means of a special installation and extraction tool.

Abstract: A mechanical magnetic key operated door lock structure particularly adapted for use in hotel locksets. An occupancy indicator is incorporated in the lock structure to indicate that the lockset is locked from the inside, thus insuring privacy for the hotel guest. In addition, means operable from outside the lock structure is provided for changing the combination of the lock so that a newly arriving guest may be provided with a key having a different combination from that used by the previous guest.

Abstract: A conventional keyed, pin-tumbler lock has an abutment portion formed on the key axially adjacent one of the key notches at the side thereof axially inward of the lock cylinder which normally axially obstructs that lock pin when the key is properly inserted in the lock cylinder key slot to prevent normal withdrawal of the key from the lock cylinder while still permitting free rotation of the lock cylinder by the key in its normal locking and unlocking movements. A key removal member is axially insertable into the key slot adjacent the key within a key axial recess and has a leading angled surface portion terminating axially in a raised surface portion which progressively move and ultimately retain that particular pin from its key pin notch and the key abutment portion obstruction, thereby permitting normal key removal from the lock cylinder.
