2022 Kia EV6 Smart Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked near the lot by the mosque in Downtown Santa Barbara. He was frustrated before I even pulled up.

Another locksmith had already been out, charged him a full rate, and left him with a key that didn't work. He described what the car was doing: it would crank, catch, and then die within two seconds. He'd been told the module was bad and that he needed to tow it to the dealer.

That symptom has a specific cause. When the immobilizer registration sequence isn't completed correctly, the car writes key data to temporary memory but not to permanent storage. The system reads the fob long enough to allow a crank, then the security logic cuts it. It looks like a hardware failure. It isn't.

I connected through the OBD port and pulled the current key memory. The previous attempt was visible: a partial write that hadn't finalized. I cleared it, retrieved the PIN by VIN, and ran a clean registration sequence from the beginning, letting each step complete fully before moving to the next. His original fob, the one the first locksmith had tried to program, came back clean. All seven buttons confirmed. Push-button start held. I let the car idle for a minute and walked him through what happened.

He'd already paid once for a job that wasn't finished. I didn't bring up what the dealer would have charged. He already knew it would have been more, and he would have had to tow the car to get there.
