2020 Lexus RX Smart Key Replacement - Fast, Affordable & Professional

Near the Botanic Garden Area in Thousand Oaks, a parent called me on a Monday afternoon. She'd already been through the dealer conversation: Thursday was the earliest appointment, and that assumed the fob was in stock, which it might not be. She had kids in after-school activities every single day that week. Three days without the RX was not a plan she could work with.

I pulled into the orthodontist parking lot about forty minutes after she called.

She met me at the car and the first thing she said was that she still had one working key, she just needed a second. That's actually the easier version of this job. All-keys-lost means a full memory wipe and reset first. Adding to an existing key means the system already knows what it's doing, I just need to introduce the new fob.

I connected my programmer to the OBD port, ran the Lexus smart key registration sequence, and cut the emergency insert blade to match her lock. The whole thing took right around thirty minutes, most of which was the car doing its timed security handshake. She tested every button herself, walked both door handles, tried the start button from the driver seat and the passenger seat, and then just stood there for a second like she expected something to go wrong.

Nothing went wrong. She had a working spare before pickup time.

The dealer quote came up in conversation on the way out. She'd been expecting to pay it because she thought it was the only option. It was a good chunk more than what she paid me, and she would have waited until Thursday to do it.
