SFIC (Small Format Interchangeable Core) and LFIC (Large Format Interchangeable Core) locks are both types of interchangeable core locking systems, but they differ mainly in size and compatibility. SFIC cores are smaller, more standardized, and widely used across multiple brands, making them easier to replace without special tools. LFIC cores are larger, often brand-specific, and may require unique tools or hardware for removal and installation.
