Hyundai Sonata OEM Door Lock Cylinder LH – 81970-C1A00 (2015-2019)

Genuine Hyundai OEM part 81970-C1A00, listed by Hyundai as Key Sub Set-Door, LH — the driver-side door lock cylinder for the LF Sonata. Supplied as a sub-assembly rather than the complete lock set.

WHAT'S IN THE BOX:

• 1 × front left (LH) door lock cylinder
• 2 × mechanical keys (81996-3S000)

The keys are cut to this cylinder only. This part does NOT include the ignition cylinder, trunk cylinder (81250-C1A00), glove box cylinder (81521-2LA00), or a remote.

Application is 2015-2019 Hyundai Sonata and 2016-2019 Sonata Hybrid, position front left. The unit is mechanical only — no transponder, no immobilizer involvement, no programming required. If the customer needs one key across the car, either re-pin this cylinder to the existing code or step up to the full set 81905-C1000, which also covers trunk and glove box.

Standard replacement for punched, drilled or seized driver door locks, and for smart-key Sonatas where the emergency blade no longer turns the door. New in genuine Hyundai packaging.
