2023 Lexus RX Smart Key Replacement - Fast, Affordable & Professional
Got called to Conejo Oaks neighborhood where a 2023 RX owner discovered her spare key wouldn't start the car. Just clicked once and nothing.
She'd bought it online, had another locksmith program it. The fob locked and unlocked fine, but push-to-start ignored it completely. The seller swore it was the right part. HYQ14FLC, matched the FCC ID on her working key.
I connected my Autel IM608 and found the problem right away. The spare was registered but showing as "Key Type Mismatch" in the BCM. Someone had installed a recycled 4D chip instead of the DST-AES this system needs. The RX's immobilizer saw it as an imposter and blocked ignition.
Cut a new TOY54 blade, loaded a virgin DST-AES chip, and ran the registration through the OBD port. The 2023 system takes about 12 minutes to complete, with three security delays built in. No rushing it.
When the new key finally fired up the engine, she asked why the other one seemed to work at first. That's the thing with these newer Lexus systems: they'll let a wrong key operate the doors to avoid locking you out, but they won't compromise on starting. Smart design.
She paid a fraction of dealer pricing and got a key that actually works.

What certified service looks like in reviews
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”
