A Smart Key is the type of key your 2022 Lexus UX uses. It contains a programmed chip that communicates with your vehicle's immobilizer system to verify it is an authorized key before the engine will start. It also has 4 buttons for remote lock, unlock, and other functions depending on your trim level. Without proper programming, even a perfectly cut key will not start your Lexus because the security system will reject it.

2022 Lexus UX Smart Key Replacement - Fast, Affordable & Professional

Her father had just been seen by a specialist and she was loading him into the car when the fob stopped working. Her 2022 Lexus UX wouldn't respond. She pressed start, nothing. She held the fob against the button, nothing. It was 6pm at a specialist's office in Spring Valley and she had an elderly parent in a wheelchair next to a car that wouldn't move.

The dealer was closed. She called me.

I connected my IM608 to OBD as soon as I got the door open. Her Smart Key, FCC ID HYQ14FBZ, was a 4-button smart key on the newer 8A platform. The old fob's CR2032 battery had corroded the contact and the chip wasn't transmitting. I replaced the fob, programmed the new one, and tested every function.

From her call to engine running was 48 minutes at $298. She got her father home that evening in his own seat, in his own car, without calling a second ride or transferring a wheelchair into an Uber.

Lexus UX Mobile Service FAQ

Real costs, no dealer surprises

How long does the Lexus dealer take for key replacement?▼

The actual programming at the dealer takes about an hour in the service bay. But the real wait is getting to that point. Lexus owners of 2023 and 2024 RX and NX models report waiting three to six months just for the physical fob to be allocated under the Lexus second key program, then another two weeks to get a programming appointment. One NX350h owner said the dealer visit itself took about 90 minutes including a car wash, but only after months of waiting for the key to arrive. With us, the whole process is same-day.
