2000 Infiniti G20 Transponder Key Replacement - Fast, Affordable & Professional

I got a call from a woman parked in a garage in Downtown Santee. Weekday evening, shopping center, and her key had stopped doing what she needed it to do. The door was locked. Her infant was strapped into the car seat inside. She had stepped away for thirty seconds to return a cart.

She was calm on the phone, but I could hear what kind of calm that was.

I got there and opened the door first. That was the only thing that mattered at that moment. She got the baby out, and both of them sat on a bench nearby while I worked.

Once I knew everyone was okay, I diagnosed the key itself. The transponder chip in her ignition key was the issue, not just a worn blade and not a dead remote battery. On this generation G20, the chip inside the key head has to communicate with the vehicle's immobilizer every single time you turn the key. When that communication fails, the engine will crank and then cut out almost immediately. That is exactly what she had been dealing with before she locked herself out entirely.

I cut a new key blade to the vehicle and programmed a replacement transponder chip to her car on site. No tow. No dealer wait. She was driving home before the garage got busy with the dinner crowd.

The baby slept through most of it in the stroller beside us. Some jobs I remember for the technical side. That one I remember because of the bench.
