2010 Toyota Prius Smart Key Replacement - Fast, Affordable & Professional

He called me from the cell phone lot at the airport. Had been gone a week, walked out to his 2010 Prius, and nothing. No response from the fob, doors locked, and the car just sitting there ignoring him.

The part that made it worse: he had tucked his bag in the trunk before the trip to save space at the gate. Emergency insert key was in that bag. The bag was in the trunk. The trunk was locked.

I was at Libby Lake earlier that morning and got to him in under an hour. First thing was getting into the car without triggering anything, which is routine work with the right tools. Once inside, I found the bag, got the insert key out, and he stood there just shaking his head.

From there I pulled the fob apart right on the hood. The CR1632 was completely flat. Swapped it in, reseated everything, and let him test the touch unlock on both front doors himself. Both handles responded, start button saw the fob, all four buttons working.

I connected to the OBD port to check whether any communication faults had logged during the dead-battery period. There was a stored fault from the security system losing contact with the fob. Cleared it, confirmed the system saw the key cleanly, and that was it.

He drove home that afternoon. The dealer's earliest appointment was Thursday. He found me on Tuesday. The math on waiting versus calling a mobile locksmith was pretty obvious once he was back behind the wheel.
