RHAOCZIYAUTO Ignition Lock Cylinder Housing Assembly for Kia Optima 2011-2015 — Complete Replacement Kit with Two Keys

A complete ignition lock switch housing assembly built to replace worn cylinders and door locks on Kia Optima models from 2011 through 2015.

If your Optima’s key no longer turns smoothly, the ignition feels loose, or the door lock is unreliable, this RHAOCZIYAUTO replacement kit restores starting and locking function in one repair. The package includes the ignition housing, lock cylinder, left driver’s door lock, two keys and the small hardware needed for a direct swap — designed to match OEM mounting points and part numbers for a straightforward installation.

What exactly comes in the replacement kit and why does it matter?

The kit supplies every primary component that commonly fails in older Optima ignition assemblies, so you won’t need to source separate parts. Having all pieces in one set reduces installation time and ensures compatibility across the mechanism.

• Ignition lock housing — the structural mount for the cylinder
• Lock cylinder — the keyed tumblers that engage the ignition
• Left driver’s door lock — restores entry security and key function
• Two cut keys, bolts and a clamp — ready for immediate fitment

How do I know this fits my Kia Optima?

This replacement matches the factory fit for Optima sedans built from 2011 to 2015 and cross-references common OEM part numbers used in repair. Confirm fit by comparing your current part numbers or visual match before ordering.

• Compatible model years: 2011, 2012, 2013, 2014, 2015
• Cross-reference parts: 81905-2T040, 81970-2TA00, 81900-2TD00, 81905-2T540
• Designed for plug-and-play mounting with existing steering column hardware

What materials and durability can I expect from this assembly?

The housing combines impact-resistant ABS plastic with reinforced metal internal parts to balance lightweight installation and long service life. Materials are chosen to resist daily wear from key cycles and maintain reliable mechanical action under normal driving conditions.

• ABS plastic housing for structural support and impact resistance
• Metal lock cylinder components for wear resistance where keys engage
• Sturdy clamp and bolts included to secure the assembly in place

How difficult is installation and what tools will I need?

Installation is straightforward for a DIYer comfortable with basic steering column disassembly; it typically requires common hand tools and about an hour depending on experience. If you’re unsure, a local mechanic can complete the swap quickly using the included parts.

• Common tools: screwdrivers, socket set, and trim removal tools
• Includes necessary clamp and bolts to simplify reassembly
• Two keys provided — ready to use after mechanical installation
