Key Replacement - Save vs Dealer in San Diego

2011 Toyota Tundra Transponder Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked inside a gated community near North Broadway in Escondido. His 2011 Tundra was sitting in guest parking, wouldn't start, and he had no backup key. The tow company couldn't get past the gate without a resident escort, and he had no way to escort anyone because he was stuck on foot inside his own complex.

I drove in behind a returning resident and walked over with my bag.

The truck would crank but die immediately. Classic immobilizer symptom. The transponder chip in his key had given up. Not the key blade, not the ignition cylinder, just the chip inside the key head that the truck needs to read before it allows the engine to stay running. He had been using the same key for eleven years and never thought about it until the morning it stopped working.

I decoded the lock, cut a fresh key blade to match, and programmed the new transponder chip to the immobilizer on site. Tested it several times, cold starts and restarts, before I called it done. The truck never moved an inch during the whole job.

He mentioned the dealer was his next call if I hadn't picked up. He would have needed the tow, the wait for an appointment slot, and a bill that was a significant chunk more than what he paid me. Instead the whole thing happened in his parking lot while he stood there drinking a coffee he'd walked to get from the corner.
