1. A method of separating a first component body from a second component body, the first and second component bodies being joined together via an adhesive, the method comprising:
aligning a ramp lock extractor (RLE) lift tool with an RLE key slot extending through the first component body, the RLE lift tool including a tool stem with a plurality of ramp pins projecting outward from lateral sides of the tool stem, and the RLE key slot including a through-hole with a plurality of helical ramps located inside the RLE key slot on lateral sides of the through-hole;
inserting the RLE lift tool into the RLE key slot such that the ramp pins are inside the RLE key slot and a distal tip of the tool stem abuts the second component body; and
rotating the RLE lift tool within the RLE key slot such that the ramp pins slide along underside surfaces of the helical ramps causing the distal tip of the tool stem to press against the second component body and thereby separate the first component body from the second component body.
