Detachable Identification Key Head

A key, comprising:

• a key blade;
• a socket connected at one end of the key blade, the socket having an irregular truncated pyramid shape that includes:
• a first base having a rectangular shape and disposed at an entrance of the socket,
• a second base having a rectangular shape and disposed at a bottom of the socket, the second base being smaller than the first base in dimension,
• a lower side surface having an isosceles trapezoidal shape, the lower side surface extending perpendicularly to the first and second bases
• a right side surface and a left side surface, each of the right and left side surfaces having a rectangular trapezoid shape and converging with each other at the bottom of the socket;
• an upper side surface having an isosceles trapezoid shape and converging to the lower side surface at the bottom of the socket;
• wherein a dimension of a cross section of the socket decreases in a direction away from the key blade;
• wherein the socket further includes a fastener channel formed in the socket and extending through the upper side surface, is disposed parallel to the first and second bases, and also extends at least partially through the right and left side surfaces;
• wherein the lower side surface includes a centering ridge, the centering ridge disposed along an axis A-A′, the axis A-A′ extending perpendicularly relative to the first and second bases;
• and
• a key head that releasably engages and envelops the socket to connect the key head with the key blade, the key head forming a cavity that matingly engages the socket, the key head further forming centering channel that slidably accepts the centering ridge, and a through hole that is aligned with the fastener channel;
• and
• a fastener extending through the fastener channel and the through hole, the fastener preventing removal of the key head from the socket when present within the fastener channel.

A method of constructing a key, comprising:

• providing an original key having an integrated key blade with an original key head;
• cutting the original key head from the key blade;
• shaping a cut end of the key blade into an irregular truncated pyramid shape, wherein the irregular truncated pyramid shape forms a socket, the socket comprising:
• a first base having a rectangular shape and disposed at an entrance of the socket,
• a second base having a rectangular shape and disposed at a bottom of the socket, the second base being smaller than the first base in dimension,
• a lower side surface having an isosceles trapezoidal shape, the lower side surface extending perpendicularly to the first and second bases
• a right side surface and a left side surface, each of the right and left side surfaces having a rectangular trapezoid shape and converging with each other at the bottom of the socket;
• an upper side surface having an isosceles trapezoid shape and converging to the lower side surface at the bottom of the socket;
• wherein a dimension of a cross section of the socket decreases in a direction away from the key blade;
• wherein the socket further includes a fastener channel formed in the socket and extending through the upper side surface, is disposed parallel to the first and second bases, and also extends at least partially through the right and left side surfaces;
• wherein the lower side surface includes a centering ridge, the centering ridge disposed along an axis A-A′, the axis A-A′ extending perpendicularly relative to the first and second bases;
• providing a key head, and releasably engaging the key head onto the socket, wherein the key head forms a cavity that matingly engages the socket;
• while releasably engaging the key head, aligning the key head with the key blade by engaging the centering ridge with the centering channel that slidably accepts the centering ridge;
• securing the key head onto the key blade by inserting a fastener through a through hole formed in the key head in aligned relation with the fastener channel.
