📦 "With Tumblers" (Uncoded Setup) Explained
When a parts listing specifies "OEM New Part (With Tumblers)," it means you are buying a factory uncoded service kit.
• Kit Components:
The box contains a raw metal mechanical lock housing, a selection of separate brass lock wafers (tumblers) of varying depths, and a packet of small retention springs. It does not ship with pre-cut physical keys.
• The Coding Process:
A professional automotive locksmith or a dealership service department will use your original working ignition key to determine the correct depth configuration. They drop the matching brass wafers into the empty cylinder slots so that the assembly matches your existing key profile exactly.
