Abstract
A cylinder lock device including: a body housing having a bore having a first end and a second end, with a direction of elongation defining an axial direction for the device; a rotatable cylindrical plug in the bore, the plug having an axially extending key slot from the first end; a plurality of tumbler pins deployed at least partially within the plug and displaceable by a key to enable rotation of the plug; and an opening mechanism comprising a shaft connected to a key emulator and wherein the key emulator is translatable into the key slot from within the body housing, the key emulator shaped to match and engage the plurality of tumbler pins, and adapted to displace the plurality of tumbler pins, thereby selectively enabling rotation of the plug.

A cylinder lock device comprising:
- a body housing having a bore having a first end and a second end, with a direction of elongation defining an axial direction for the device;
- a rotatable cylindrical plug in the bore, the plug having an axially extending key slot from the first end;
- a plurality of tumbler pins deployed at least partially within the plug and displaceable by a key to enable rotation of the plug;
- and
- an opening mechanism comprising a shalt connected to a key emulator and wherein the key emulator is translatable into the key slot from within the body housing, the key emulator shaped to match and engage the plurality of tumbler pins, and adapted to displace the plurality of tumbler pins, thereby selectively enabling rotation of the plug.
A method of forming a cylinder lock device comprising the steps of:
- forming a bore in a body housing of the cylinder lock device having a first end and a second end, the body housing having a direction of elongation defining an axial direction for the device;
- inserting a rotatable cylindrical plug in the bore, the plug having an axially extending key slot from the first end;
- configuring a plurality of tumbler pins at least partially within the plug, whereby a key displaces the tumbler pins to enable rotation of the plug;
- and
- deploying an opening mechanism comprising a shaft and a shaft key emulator, wherein the key emulator is translated into the key slot from within the body housing and is shaped to match and engage the plurality of tumbler pins and to displace the plurality of tumbler pins, thereby selectively enabling rotation of the plug.
