How do these cylinders restore door locking function?

• Includes two matching metal keys for immediate use.
• Precision-machined tumblers to reduce binding and sticking.
• Supplied with C-clips for secure retention in the door handle assembly.
• Direct-fit dimensions intended to mate with original latch hardware.
