In this review the focus is on a direct replacement ignition lock switch assembly designed for the Kia Optima 2011-2015. The bottom line: this assembly is aimed at owners who need a full lock and ignition solution that restores factory-like function without chasing multiple parts. It includes the ignition lock housing, lock cylinder, left driver door lock, bolts, clamp and two matching keys, and customers report the unit installs easily and functions like the original, making it a practical repair choice for DIY mechanics and independent shops.

Key Features

• Vehicle Fitment: Fits Kia Optima 2011 through 2015 to ensure direct compatibility with models covered by those years.
• Complete Kit: Includes ignition lock housing, lock cylinder, left driver door lock, bolts, lock housing clamp and two keys so buyers receive a ready-to-install replacement.
• Replace Part Numbers: Replaces 81905-2T040, 81970-2TA00, 81900-2TD00 and 81905-2T540 so it matches the common OEM references for this repair.
• Durable Materials: Built with ABS plastic and strong metal components to resist impact and provide long service life under normal vehicle use.
• Reliable Performance: Customers note the ignition and door lock combination works like a factory part, restoring reliable start and door locking operation.

Who It's For

This assembly is best for Kia Optima owners from model years 2011 to 2015 who need a full ignition and driver door lock replacement rather than sourcing separate cylinders or housings. It suits DIY enthusiasts comfortable with basic disassembly of dash and door components and independent repair shops handling mid-range repairs.

It is less suited to owners of other Kia models or Optima years outside 2011-2015, and those who only need a single component such as just a key blade or an electronic remote should look for that specific part instead.
