Morphology
The phrase evokes the literal image of animals 'locking horns' to fight, so a learner who knows 'lock' and 'horns' can infer a sense of physical confrontation and, by extension, conflict. However, the metaphorical extension to verbal/argumentative disputes and its idiomatic, non-literal use may not be fully predictable without prior exposure, making it only partially transparent.
Etymology
The phrase lock horns may come from male animals such as deer, goats, or bulls that fight by literally locking their horns together and pushing until one gives up. So today lock horns means to 'argue' or 'be in a strong conflict'.
