Electronic lock core replacement methods

A method of replacing a first electronic lock core of an electronic lock with a second electronic lock core, the method comprising:

• coupling a control key with a first electronic lock core plug of the first electronic lock core to unlock the electronic lock;
• rotating the first electronic lock core plug to align a notch within a flange of the first electronic lock core plug with a first screw guard that is installed into a first screw access port of the first electronic lock core;
• removing the first screw guard from the first screw access port of the first electronic lock core, wherein the first screw access port provides access to a screw head of a first screw, wherein the first screw guard prevents access to the screw head when the first screw guard is inserted into the first screw access port, and wherein the first screw is inserted into a first retainer ramp;
• rotating the first screw in a first direction to cause the first retainer ramp to move axially along the first screw from a second position to a first position, wherein moving the first retainer ramp from the second position to the first position causes a first control lug to disengage from an electronic lock housing of the electronic lock;
• removing the first electronic lock core from an aperture of the electronic lock housing of the electronic lock;
• and
• installing the second electronic lock core into the electronic lock housing, wherein installing the second electronic lock core comprises:
• inserting the second electronic lock core into the aperture of the electronic lock housing such that the second electronic lock core is positioned so that a face of the second electronic lock core is exposed to a user via the aperture of the electronic lock housing;
• rotating a second screw of the second electronic lock core in a second direction to cause a second retainer ramp to move axially along the second screw from a first position to a second position, wherein moving the second retainer ramp from the first position to the second position causes a second control lug to engage with the electronic lock housing;
• inserting a second screw guard into a second screw access port of the second electronic lock core;
• and
• using the control key, rotating a second electronic lock core plug of the second electronic lock core to align a notch within a flange of the second electronic lock core plug such that the second screw guard cannot be removed from the second screw access port.
