Abstract
A system and method for a key, comprising a key blade having a socket that releasably engages a key head. A method includes cutting an original key head from an original key, forming a socket onto a cut end of the key blade, and attaching a key head onto the socket.
Claims15
A key head adapted to interface with a key blade, the key blade arranged with a trapezoidal chamfered end, the key head comprising:
- a socket formed in the key head, wherein the socket is arranged to matingly engage the trapezoidal and chamfered end of the key blade, the socket including a concave feature having an irregular hollow truncated pyramid shape that includes:
- a first base having a rectangular shape and disposed opposite a closed end of the socket,
- a second base having a rectangular shape and disposed at the closed end of 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 between the first and second bases;
- a right side surface and a left side surface, each of the right and left side surfaces converging in a direction from the first base towards the second base;
- an upper side surface extending between the first and second bases;
- wherein the socket further includes a fastener channel disposed parallel to the first and second bases.

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 comprises:
- a first base having a rectangular shape disposed opposite a free end of the irregular truncated pyramid shape,
- a second base having a rectangular shape and disposed at a free end of the irregular truncated pyramid shape, 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 and between 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 towards the free end of the irregular truncated pyramid shape;
- an upper side surface having an isosceles trapezoid shape and converging to the lower side surface towards the free end of the irregular truncated pyramid shape;
- wherein the irregular truncated pyramid shape further includes a fastener channel formed in the upper side surface;
- providing a key head, and releasably engaging the key head onto the irregular truncated pyramid shape of the key blade, wherein the key head forms a cavity that matingly engages the irregular truncated pyramid shape of the key blade;
- 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.
