2021 Lexus UX Smart Key Replacement - Fast, Affordable & Professional
A customer at the country club in Vista told me he'd already paid another locksmith full price for a 2021 Lexus UX key that never worked. The engine cranked but the smart system killed fuel after two seconds. The other locksmith said the smart ECU was bad and walked away.
The ECU was fine. The locksmith hadn't completed the full Lexus key registration. The smart system requires a specific security sequence including seed calculation and a timed registration. Rushing it means the key writes temporarily but doesn't commit to permanent memory.
I used my TOY43 Lishi to verify the blade cut, then connected through OBD. I cleared the failed registration, ran a clean smart key learn with the full security timer, and confirmed the new key was permanently written. His key with remote, FCC ID HYQ14FBZ, started the engine clean on three consecutive tests. I showed him the IM608 confirmation screen.
He paid me $369. Dealer charges $663 for the same work. He'd already paid the first locksmith too. But I could make sure the job was actually done right this time.
