1. A locking system, comprising:
a first cylinder portion extending along a main axis, the first cylinder comprising:
a first central hole extending along the main axis;
a first plurality of pin bores, each pin bore of the first plurality of pin bores axially extending along the main axis, the first plurality of pin bores annularly arranged and spaced around the first central hole;
a second cylinder portion extending along the main axis, the second cylinder portion rotatably coupled with the first cylinder portion with a common shear plane between the first cylinder and the second cylinder, the common shear plane perpendicular to the main axis, the second cylinder portion comprising:
a second central hole extending along the main axis, the second central hole aligned with the first central hole;
a second plurality of pin bores, each pin bore of the second plurality of pin bores axially extending along the main axis, the second plurality of pin bores annularly arranged and spaced around the second central hole, each pin bore of the second plurality of pin bores aligned with a corresponding pin bore of the first plurality of pin bores;
a front plate coupled and rotatable with the first cylinder portion, the front plate perpendicular to the main axis, the front plate comprising:
a third central hole extending along the main axis, the third central hole aligned with the first central hole;
a plurality of keyholes, each keyhole of the plurality of keyholes axially extending along the main axis, the plurality of keyholes annularly arranged and spaced around the third central hole, each keyhole of the plurality of keyholes aligned with a corresponding pin bore of the first plurality of pin bores;
a plurality of code pins, each code pin of the plurality of code pins slidably disposed within a corresponding pin bore of the first plurality of pin bores;
a plurality of spring-loaded driver pins, each spring-loaded driver pin of the plurality of spring-loaded driver pins mounted in a corresponding pin bore of the second plurality of pin bores, each spring-loaded driver pin of the plurality of spring-loaded driver pins configured to contact a corresponding code pin of the plurality of code pins at a common junction, each spring-loaded driver pin of the plurality of spring-loaded driver pins configured to push a corresponding code pin of the plurality of code pins towards a corresponding keyhole of the plurality of keyholes; and
a main shaft disposed within the first central hole and the second central hole, the main shaft extended along the main axis, the main shaft slidable within the first central hole and the second central hole along the main axis; and
a key comprising:
an elongated key shaft, the elongated key shaft configured to be insertable into the third central hole; and
a plurality of key needles extended parallel with the elongated key shaft, the plurality of key needles arranged and spaced annularly around the elongated key shaft, each key needle of the plurality of key needles configured to be insertable into a corresponding keyhole of the plurality of keyholes,
wherein the main shaft configured to be coupled to and rotatable with one of the first cylinder portion and the second cylinder portion responsive to the elongated key shaft being inserted into the first central hole via the third central hole,
wherein the spring-loaded driver pin of the plurality of spring-loaded driver pins comprises a driver pin and a pin spring, the driver pin coupled to the pin spring from one end along the main axis, wherein the driver pin is coupled to a first code pin from a second opposing end of the driver pin.
