A magnetic lock and key assembly includes a magnetic lock assembly. The magnetic lock assembly includes a plunger translatable between a locked position and an unlocked position. A detent is extendable when the plunger is in the locked position and retractable when the plunger is in the unlocked position. A lock magnet is translatable with the plunger and has an end defined by a lock magnet north pole and a lock magnet south pole. The magnetic lock and key assembly further includes a magnetic key assembly having a key magnet. The key magnet has an end defined by a key magnet north pole and a key magnet south pole. At least one of the lock magnet and the key magnet is rotatably supported to facilitate automatic magnetic attractive alignment, attraction of the lock magnet toward the key magnet, and translation of the plunger to the unlocked position.

1. A magnetic lock and key assembly, comprising: a magnetic lock assembly including: a lock body defining a chamber;a plunger disposed within the chamber and being translatable in a longitudinal axial direction between a locked position and an unlocked position;a resilient member urging the plunger toward the locked position;a detent being extendable when the plunger is in the locked position and retractable when the plunger is in the unlocked position;a lock magnet disposed within the chamber and being translatable with the plunger as the plunger translates between the locked position and the unlocked position, the lock magnet having an end defined by a lock magnet north pole and a lock magnet south pole;a magnetic key assembly including: a collet configured to connect to the lock body;a key magnet supported within the collet, the key magnet having an end defined by a key magnet north pole and a key magnet south pole;wherein at least one of the lock magnet is rotatably supported by the lock body and the key magnet is rotatably supported by the collet to facilitate automatic magnetic attractive alignment of the lock magnet and the key magnet about the longitudinal axial direction and magnetic attraction between the lock magnet north pole and the key magnet south pole and between the lock magnet south pole and the key magnet north pole to translate the plunger to the unlocked position. 2. The magnetic lock and key assembly of claim 1, wherein the key magnet is rotatably supported by the collet. 3. The magnetic lock and key assembly of claim 2, wherein the key assembly further includes: a rod supported within the collet and being translatable between an actuated position and a non-actuated position; anda carrier translatably supported within the collet and rotatably housing the key magnet, the carrier being connected the rod such that the carrier and the key magnet are translatable with the rod between the actuated position and the non-actuated position. 4. The magnetic lock and key assembly of claim 1, wherein the lock magnet has an annular shape including the lock magnet north pole and the lock magnet south pole and the key magnet has an annular shape including the key magnet north pole and the key magnet south pole. 5. The magnetic lock and key assembly of claim 1, wherein the key magnet magnetically corresponds to the lock magnet. 6. A magnetic key assembly, comprising: a collet configured to connect to a magnetic lock assembly;a rod supported within the collet and being translatable in a longitudinal axial direction between an actuated position and a non-actuated position;a key magnet being translatable within the collet due to movement of the rod between the actuated position and the non-actuated position, the key magnet having a longitudinal axial end opposite the rod, and the longitudinal axial end being defined by a key magnet north pole and a key magnet south pole;wherein connecting the collet to the magnetic lock assembly and positioning the key magnet near a lock magnet of the magnetic lock assembly having an end defined by a lock magnet north pole and a lock magnet south pole automatically magnetically attractively aligns the key magnet and the lock magnet and attracts the lock magnet toward the key magnet to unlock the magnetic lock assembly. 7. The magnetic key assembly of claim 6, wherein the key magnet is rotatably supported by the rod. 8. The magnetic key assembly of claim 7, further comprising a carrier translatably supported within the collet and connected to the rod, the carrier rotatably housing the key magnet. 9. The magnetic key assembly of claim 6, wherein the key magnet has an annular shape including the longitudinal axial end and an outer circumferential surface adjacent the longitudinal axial end. 10. The magnetic key assembly of claim 9, wherein the key magnet north pole and the key magnet south pole each define substantially one-half of the longitudinal axial end. 11. The magnetic key assembly of claim 6, wherein the key magnet has an annular shape defined by a first semi-annular key magnet section connected to a second semi-annular key magnet section, the first semi-annular key magnet section including the key magnet north pole and the second semi-annular key magnet section including the key magnet south pole. 12. The magnetic key assembly of claim 11, wherein the key magnet north pole is a first key magnet north pole and the key magnet south pole is a second key magnet south pole, the first semi-annular key magnet section further including a first key magnet south pole axially opposite the first key magnet north pole, and the second semi-annular key magnet section further including a second key magnet north pole axially opposite the second key magnet south pole. 13. A magnetic lock assembly, comprising: a lock body defining a chamber having a first end and an opposite second end;a plunger disposed within the chamber and being translatable in a longitudinal axial direction between a locked position and an unlocked position;a resilient member urging the plunger toward the locked position;a detent being extendable when the plunger is in the locked position and retractable when the plunger is in the unlocked position;a lock magnet being translatable with the plunger as the plunger moves between the locked position and the unlocked position, the lock magnet having a longitudinal axial end proximate the second end of the chamber, and the longitudinal axial end being defined by a lock magnet north pole and a lock magnet south pole;wherein positioning a key magnet having an end defined by a key magnet north pole and a key magnet south pole proximate the second end of the chamber automatically magnetically attractively aligns the key magnet and the lock magnet about the longitudinal axial direction, attracts the lock magnet toward the key magnet, and moves the plunger to the unlocked position such that the detent may retract;wherein the lock magnet further includes an outer circumferential surface adjacent the longitudinal axial end; andwherein the lock magnet has an annular shape including the outer circumferential surface and the longitudinal axial end. 14. The magnetic lock assembly of claim 13, wherein the lock magnet north pole and the lock magnet south pole each define substantially one-half of the longitudinal axial end. 15. A magnetic lock assembly, comprising: a lock body defining a chamber having a first end and an opposite second end;a plunger disposed within the chamber and being translatable in a longitudinal axial direction between a locked position and an unlocked position;a resilient member urging the plunger toward the locked position;a detent being extendable when the plunger is in the locked position and retractable when the plunger is in the unlocked position;a lock magnet being translatable with the plunger as the plunger moves between the locked position and the unlocked position, the lock magnet having a longitudinal axial end proximate the second end of the chamber, and the longitudinal axial end being defined by a lock magnet north pole and a lock magnet south pole;wherein positioning a key magnet having an end defined by a key magnet north pole and a key magnet south pole proximate the second end of the chamber automatically magnetically attractively aligns the key magnet and the lock magnet about the longitudinal axial direction, attracts the lock magnet toward the key magnet, and moves the plunger to the unlocked position such that the detent may retract; andwherein the lock magnet has an annular shape defined by a first semi-annular lock magnet section connected to a second semi-annular lock magnet section, the first semi-annular lock magnet section including the lock magnet north pole and the second semi-annular lock magnet section including the lock magnet south pole. 16.
