YzusGomumu Driver-side Front Left Door Lock Cylinder for 2009-2015 Sonata — OE Fit, Includes 2 Keys

YzusGomumu's driver-side front left door lock cylinder is a direct-fit replacement for 2009–2014 Hyundai Sonata and 2011–2015 Sonata Hybrid models, supplied with two keys for immediate installation.

When a worn or damaged door lock cylinder leaves your Sonata vulnerable or prevents the door from locking properly, a precise replacement restores security and convenience. This YzusGomumu unit matches OE fitment (OE numbers 81970-3SA00 / 819703SA00) and ships with two keys, so you can swap the part without modifying the door hardware. Built from durable materials and designed for repeated use, it aims to return factory-style operation and reduce future maintenance needs.

How will this lock cylinder fit my Sonata?

This cylinder is engineered to be a direct replacement for the specified model years and trims. Check the OE part number stamped on your old cylinder to confirm compatibility before ordering.

• Compatible with 2009–2014 Hyundai Sonata (gasoline) and 2011–2015 Sonata Hybrid
• Matches OE numbers 81970-3SA00 and 819703SA00 for correct fit

What comes in the package and what tools are typically needed?

The product is supplied as a full integrated kit so you have everything needed to replace the cylinder. Basic hand tools are usually sufficient for the swap and most owners can complete the job without specialty equipment.

• Includes: 1 door lock cylinder and 2 cut keys
• Common tools: screwdriver set, panel trim tool, and pliers
• Typical install time: 20–45 minutes depending on experience

How durable and secure is the YzusGomumu replacement cylinder?

Constructed from wear-resistant materials and using an anti-theft lock core design, this cylinder aims to provide reliable daily operation and enhanced protection against tampering. It’s made for frequent use without premature failure.

• High-quality materials for improved wear resistance and longevity
• Anti-theft core design helps deter illegal opening attempts

Will this affect my door electronics or remote locking?

The mechanical cylinder replaces only the physical lock; it does not alter factory electronic door modules or remote keyless entry systems. If your vehicle uses an electronic immobilizer or transponder key, confirm key compatibility prior to purchase.

• Mechanical replacement — no changes to vehicle wiring or modules
• Transponder systems: verify whether keys need programming for immobilizer functionality
• If remote entry issues persist, diagnose the vehicle’s central locking module separately

Who this is for: This YzusGomumu driver-side lock cylinder is aimed at owners of compatible Hyundai Sonata sedans and hybrids who need a reliable, OEM-style mechanical replacement. It is suitable for DIY mechanics who want a straightforward swap using common tools, fleet managers seeking cost-effective repairs, and anyone replacing a damaged or worn lock cylinder without changing the vehicle’s factory door hardware.
