2007 Lexus GS Smart key Replacement - Fast, Affordable & Professional
Got a call from a woman near Strathearn Historical Park in Simi Valley. Her 2007 Lexus GS 350 had one working smart key left, and her dealer had quoted her a number that made her go quiet on the phone when she repeated it back to me. She wanted a spare before she was down to zero.
The third-gen GS (S190 chassis) runs Toyota's Smart Key system with the HYQ14AAB fob, board number 271451-0140, and a Texas Instruments 4D-67 chip inside. The car's smart ECU, part of the immobilizer on the 93C66 EEPROM, handles the encrypted challenge-response every time you hit the start button. Real security, but not something that requires a dealer bay.
I connected my Smart Pro through the OBD-II port in about two minutes. The system picked up her existing key registration, and I added the new HYQ14AAB alongside it. Cut the emergency insert blade on site from the key code. Whole thing took maybe 25 minutes, most of that just waiting on the timed registration cycle the ECU runs.
When I handed her the second fob, she clicked it a few times, watched the doors lock and unlock, then just held it like she was testing the weight. "That's it?" That was it.
She kept a good chunk of what the dealer wanted. And she never had to leave the neighborhood.

What honest rates sound like in reviews
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
