Will I need a technician to install this, or can I do it myself?

Installation requires disconnecting the negative battery terminal, unplugging the old module, and bolting in the new one. Basic hand tools are all you need. The real work is making sure your battery is disconnected before you touch anything electrical.

Does this module come programmed for my car, or will I need to reprogram it?

This is factory-calibrated for the 2016 Optima 2.4L — it should initialize and communicate with your engine immediately after installation. If your vehicle won't start or throws codes, you may need a dealer scan to verify compatibility with your specific VIN.

What's the return policy if the module doesn't work in my car?

Contact our support team with a photo of the part number on the module and your vehicle's VIN. We handle returns case-by-case depending on whether the module is defective or incompatible.
