2018 Mitsubishi Outlander Sport Smart Key Replacement - Fast, Affordable & Professional

I got a call from a guy up in Simi Hills, near the western edge where the neighborhoods start to thin out into the hills. He told me upfront that he'd already paid another locksmith to cut and program a key for his 2018 Outlander Sport. The car would crank, fire for about two seconds, and then die. He'd been told the body control module was bad and the other tech had packed up and left him with a bill and a car that still didn't start.

I asked him to describe exactly what the engine did. Two-second start then stall is a specific thing. That's the immobilizer cutting fuel after the engine fires. The key was recognized just enough to allow cranking, but the registration never fully committed. A partial write. It happens when the programming sequence gets rushed or the confirmation step gets skipped before the module finishes its timed cycle.

The module wasn't bad. The job just wasn't finished.

I connected through the OBD port, cleared the incomplete key data, and ran a clean registration sequence from the beginning, letting the full timed cycle complete before confirming. Three consecutive start tests, clean every time. Showed him the confirmation on the tool screen so he could see for himself that the key was permanently stored, not just temporarily accepted.

He'd already paid once for a job that wasn't done. I couldn't fix that part. But the car started, and he knew exactly what had gone wrong and why it didn't happen this time.
