Key Replacement - Save vs Dealer in Ventura County

2013 Lexus GS Smart Key Replacement - Fast, Affordable & Professional

A Camarillo Heights call came in on a Tuesday afternoon. The owner had parked in his driveway, gone inside, and come back out to a car that acted like it had never seen his fob before. Key-not-detected on the dash, touch unlock on both front handles doing nothing, start button just sitting there lit up and useless.

He had already bought a replacement fob online. It was sitting in the box, unregistered, which is exactly where it was going to stay until someone with the right diagnostic equipment showed up.

I pulled up, he handed me the old fob and the new one. The old battery had dropped enough voltage that the system flagged it, but the fob itself was fine. I popped it, seated a fresh CR1632 with the contacts clean, and the car woke right back up. He still wanted the second fob added as a spare, which was the smart call.

I connected to the OBD port, ran the add-a-key sequence, programmed the new fob into the system alongside the original, cut the emergency insert blade to the vehicle, and tested every function on both keys before I closed anything up. Lock, unlock, door handle touch, start. Both fobs working, both blades fitting the door lock cylinder.

He mentioned the dealer had told him to tow it in for diagnostics first. That would have been a half-day affair on a car that just needed the right tools brought to the driveway. Total time on site was under 40 minutes. He saved a good chunk compared to what the dealer route would have cost him between the tow, the diagnostic fee, and the key itself.
