2002 Toyota Camry Remote Replacement - Fast, Affordable & Professional

A woman near Mandalay State Beach in Oxnard had a 2002 Camry that was turning on her. It would start fine in the morning, then by evening the engine would crank and cut out after two seconds. No warning light, no pattern she could pin down. She thought the car had a wiring problem.

Another locksmith had already cut her a key. It worked for about ten days before things got weird.

I pulled out my VVDI2 and read the chip in her existing key. Wrong generation. He had programmed a 4D-series chip into a car that runs Toyota's older 4C fixed-code transponder system. The 2002 Camry XV30 uses the 4C, not the 4D that later models switched to. A 4D chip can sometimes pass an initial handshake but fail the fixed-code verification on later start cycles. That is exactly what was happening.

I programmed a new key with the correct 4C chip matched to her immobilizer ECU, cut a fresh TOY43 blade, and swapped in a new CR2032 in the GQ43VT14T remote shell (part number 89742-AA030) since the old battery was reading low and adding to the intermittent no-start.

She watched me test it five cold starts in a row. By the third one she stopped holding her breath.

The difference between a key that works and one that works for a week is the chip generation. I match it every time because redoing a job is bad for everyone.
