A wireless communication system includes: a locking and unlocking device configured to control locking and unlocking of a target, the locking and unlocking device including a device-side communication module configured to communicate a first signal having a first frequency band; and a key unit configured to command the locking and unlocking of the target by communicating with the locking and unlocking device. The key unit includes a unit-side communication module that communicates the first signal. The key unit is installed in the target such that a distance between the unit-side communication module and the device-side communication module is within a predetermined distance at which communication between the unit-side communication module and the device-side communication module is possible and that an axis of the unit-side antenna coil of the unit-side communication module is parallel to the axis of the device-side antenna coil.

The present disclosure provides for a lock cylinder having a rotatable spindle with at least one disc and at least one wafer housing rotatingly engaged therewith. A slidable wafer is carried on the wafer housing. A locking bar is operable to prevent rotation of the lock cylinder in a locked position and permit rotation of the lock cylinder in an unlocked position.

A trapped key interlock system is disclosed. A pair of hollow tubular casings located one inside the other and each having a series of elongate slots are used. When the lock is in a locked condition the elongate slots are aligned as inner and outer pairs with engaging members extending through the pairs of slots is preventing rotational movement of the tubular casings relative to each other. The engaging members are biased towards this locked condition. On insertion of the correctly coded key the engaging members are caused to move against the biasing force out of engagement with the slots in the outer tubular casing thereby allowing the inner tubular casing to rotate relative to the outer tubular casing and moving the lock to an unlocked condition.

A lock core includes a shell, a plug within and rotatable relative to the shell between a first position and a second position about a longitudinal axis of the plug, and a lock. The lock has a first locked position preventing rotation of the plug relative to the shell, an unlocked position allowing rotation of the plug relative to the shell and a second locked position different from the first locked position preventing rotation of the plug relative to the shell. The lock is moveable from the first locked position preventing rotation of the plug relative to the shell to the unlocked position with a first movement of the lock, the first movement having a vector component along the longitudinal axis of the plug and a vector component along an axis transverse to the longitudinal axis of the plug
