2009 Lexus GX Remote Head Key Replacement - Fast, Affordable & Professional
Guy in the Via Marina neighborhood in Oxnard called me from the airport premium lot. He had been on a business trip for a week, came back to his 2009 Lexus GX, and the thing was completely unresponsive. Fob did nothing. Held the key to the steering column ring, still nothing.
The CR1616 had died while the car sat. That part he figured out on his own. What he didn't know was that the dead battery had caused a communication fault between the HYQ1512V fob and the immobilizer ECU. The 4D-67 transponder chip inside the key head should still get read by the coil antenna around the ignition, but the ECU had flagged a mismatch and locked things up. Swapping in a fresh battery alone wasn't going to fix it.
I got to the lot in about 35 minutes. Popped the door, connected my IM608 to the OBD-II port, and pulled the fault code from the immobilizer module. His key was still registered. The ECU just needed the code cleared and the fob re-synced. New CR1616 in, fault wiped, and I cycled the ignition twice to confirm the transponder was reading clean through the coil.
Whole thing took about 20 minutes on-car. He drove home that afternoon instead of waiting until Thursday for the dealer's next opening, and he skipped the tow bill entirely.

“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”
“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”
“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”
