A magnetic coding free pin type lock cylinder structure includes: a lock cylinder housing (101), a lock knob (104) disposed within the lock cylinder housing (101), a lock cylinder front end over (102) and a lock cylinder rear end cover (103). Pin vertically moving grooves (114) and pin horizontally rotary grooves (113) are provided on an inner wall of the lock cylinder housing (101). An unlocking hole (116) for a magnetic coding key (115) is provided on the lock knob (104). A plurality of pm vertical sliding grooves (112) is provided on an outer wall of the lock knob (104). Free pins are provided in at least one of the plurality of pin vertical sliding grooves (112), and the free pins are big pins (107) or small pins (108).

A bumping preventing arrangement (10) for a lock device (38, 52, 68), the bumping preventing arrangement (10) comprising transfer member (12, 46, 64, 74) having a magnet (14), the transfer member (12, 46, 64, 74) being movable along an actuation axis (18) between a locked position (16) and an unlocked position (36); a plurality of electric conductors (20), each electric conductor (20) enclosing the actuation axis (18); and a plurality of switches (22), each switch (22) being associated with a respective electric conductor (20), and being arranged to selectively close an electric circuit comprising the associated electric conductor (20) such that eddy currents are induced in the electric conductors (20) when the magnet (14) moves along the actuation axis (18) from the locked position (16) towards the unlocked position (36). A lock device (38, 52, 68) and a method of controlling a lock device (38, 52, 68) are also provided.

A lock, in particular sash lock, with a lock housing and with a lock core rotatably mounted in the lock housing. The lock core, at a first end accessible from a front side of the lock, is formed for torque-transmitting attachment of a key, in particular a socket key. The lock has blocking means, which, when the key is removed, block rotation of the lock core in the lock housing between an open position and a closed position, and wherein the blocking means are configured to release the rotation of the lock core in the lock housing between the open position and the closed position when a key, in particular a socket key, with a predetermined magnet arrangement is mounted on the first end of the lock core. The invention further relates to a key and a lock system.

A pin tumbler lock apparatus includes a shell and a gate housed within the shell. The gate consists of a cylindrical case with multiple bores. A core, positioned within the gate, features a keyway and additional bores aligning with the gate's bores to form pin chambers when locked. Key pins within these chambers are magnetically responsive and vary in height within a defined range. Each key pin comprises a body and an oversized top element. Channels in the gate correspond to the pin chambers, allowing the top element of each key pin to move within its respective channel when a key is inserted into the keyway and the core is rotated relative to the gate.
