Key Replacement - Save vs Dealer in San Diego

2015 Scion FR-S Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from a guy in the Las Americas Area of San Ysidro at about 1 in the morning. His 2015 FR-S was parked on the street, and his only key had stopped being recognized by the car.

Not a dead battery situation. The car simply would not acknowledge the key existed. He had already been down the rabbit hole of YouTube videos and was starting to price out tow trucks for the morning.

I told him to stay put.

When I got there, the street was quiet. He was sitting on his front steps with the key in his hand like he was waiting on a verdict. I plugged into the OBD port, pulled up the Toyota-platform procedure for all-keys-lost on the FR-S, and walked through the immobilizer reset. The FR-S runs a well-documented Toyota-based security system, and this generation is a job I do on-site without any bench work or towing.

New remote head key, cut to the vehicle, programmed and registered. I walked him through the button functions and had him test it himself. Locked, unlocked, confirmed the engine started and held. The whole thing was done before 2 a.m., on the street, no tow, no appointment.

He mentioned the dealer had quoted him a number that made him pause, plus the tow on top of that, plus waiting until they could fit him in. He saved a good chunk going the mobile route, but honestly what mattered more to him at that hour was not having to leave the car on the street overnight.

I should be straight with you: there are some situations, usually edge cases on newer or heavily modified setups, where all-keys-lost requires additional steps beyond a standard OBD procedure. I will tell you that before I show up, not after. The FR-S in this generation is not one of those edge cases. It is a well-covered platform and I do these regularly.
