Key Replacement - Save vs Dealer in San Diego

2022 Toyota Prius Smart Key Replacement - Fast, Affordable & Professional

I was parked off Convoy Street in Kearny Mesa when she texted me. No preamble, just: "Prius won't recognize my key and I'm sitting in the parking lot of the cat cafe."

She had already tried the fob against the start button. It worked once, then stopped. When I pulled up, she was standing outside the car because she wasn't sure if it had locked itself or not.

First thing I did was nothing dramatic. I asked for the fob and popped the back. The CR2032 was original, which on a 2022 with some age on it means it had done its time. Voltage read low on my meter. I swapped it on the spot, reseated it, and the dash came back to life on the first touch of the handle. Door handles responding, start button waking up instantly. Good.

But she mentioned she had also bought a spare fob online and never got it programmed. So we did that while I was already there. She had her VIN ready, which she had texted me before I arrived, so I had already confirmed the correct key blank and had it cut on the drive over. With her working key present, adding the second fob to the system was the faster version of the job. I ran it through my diagnostic equipment, confirmed both keys enrolled, tested every function on both fobs at the car.

She asked what the dealer would have charged. I told her to call and find out, but that she would have also waited a few days for an appointment. She already knew the answer to that one.
