Key Replacement - Save vs Dealer in San Diego

2006 Toyota Highlander Transponder Key Replacement - Fast, Affordable & Professional

A guy in Buena Creek had just picked up a 2006 Highlander off Craigslist. Clean enough truck, fair price, one key. The seller said getting a spare was easy. He went to a hardware store first, got a key cut, tried it in the ignition, and the car cranked once and stalled. He figured the cut was off, so he had it duplicated again somewhere else. Same result.

He called me a little frustrated because he had already spent money and still had one working key.

I explained what was happening. The blade was cut fine both times. The problem was the transponder chip inside the plastic head. Without the right chip, coded to talk to that specific car, the immobilizer shuts the fuel system down almost immediately after the engine fires. The hardware store can copy the metal, but they cannot copy what is inside the plastic. That part requires programming equipment.

I met him at his place off Shadowridge in Buena Creek with the tools and a proper key blank for that vehicle. I read the transponder data from his original working key and programmed a new key to match. Cut the blade on site. He tested it twice before I packed up.

Then he asked about the dealer quote he had looked up before calling me. It was enough to make him wince. He saved a good chunk by going the mobile route, and he actually got the job done in his own driveway instead of arranging a drop-off and waiting for a callback.
