📦 "With Tumblers" (Uncoded Setup) Explained
When a factory listing specifies "OEM New Part (With Tumblers)," it identifies the part as an uncoded service kit.
• Kit Components: The package contains a brand-new mechanical lock cylinder chassis alongside an assortment of separate brass lock wafers (tumblers) and tension micro-springs. It does not ship with pre-cut keys.
• The Coding Process: An automotive locksmith or dealership service technician uses your current ignition key to determine your car's physical security pattern. They drop the matching brass wafers into the empty pathways of the core housing so that the new lock matches your original key exactly.
