Key Replacement - Save vs Dealer in Ventura County

2004 Toyota MR2 Transponder Key Replacement - Fast, Affordable & Professional

A woman staying at an Airbnb in Rancho Simi Park, Simi Valley, called me on a Friday evening. She had rented a 2004 MR2 Spyder from a friend and the only key snapped right at the head, blade stuck in the ignition, transponder chip still inside the plastic housing she was holding.

She had already called a Toyota dealer. They told her to tow it in, leave it, and they could look at it Monday or Tuesday. She had a flight Sunday.

I got there in about forty minutes. The broken blade was still sitting in the ignition cylinder, so I extracted that first. Quick job with the right pick. Then I checked the chip in the broken head. It was the 4C glass vial, which is what every third-gen MR2 Spyder runs. No buttons, no remote, just the transponder and a TOY43 blade.

I cut a fresh TOY43 blank on the Condor in the van, cloned the 4C chip onto a new key using my VVDI, and tested it. Key turned, immobilizer accepted, engine fired. The security light on the dash went out the way it should, no steady glow, no blinking.

She sat on the curb the whole time, watching me work under the hatch light. When the engine caught, she just said "oh thank god" real quietly. Whole thing took maybe twenty-five minutes. She drove to dinner, I drove home.
