Hyundai Tucson OEM Door Lock Cylinder LH – 81970-D3A00 (2016-2021)

Genuine Hyundai OEM part 81970-D3A00, catalogued by Hyundai as Key Sub Set-Door, LH and commonly listed as a door lock cylinder. This is a sub-assembly, not the vehicle's full lock set.

WHAT'S IN THE BOX:

• 1 × driver-side (LH) door lock cylinder
• 2 × mechanical keys

The keys are cut to this cylinder only. This part does NOT include the ignition cylinder, the passenger door, trunk or glove box cylinders, or a remote.

Fits 2016-2021 Hyundai Tucson. Because the cylinder ships coded to its own keys rather than to the vehicle, a customer who wants one key for everything will need the lock re-pinned to the existing key code — or the full matched set 81905-D3080, which covers ignition and door together.

Standard replacement when the door tumblers are seized, drilled or punched, or when the insert blade is lost and mechanical entry has to be restored. New in genuine Hyundai packaging, wholesale to the trade.
