2011 Lexus RX Smart Key Replacement - Fast, Affordable & Professional
A collision center on Thompson Boulevard in Ventura called me about a 2011 Lexus RX 350 that had been sitting in their bay for almost a week. The body shop had finished the repair work days earlier, but the car would not start. They had called another locksmith to program a replacement smart key. That tech got partway through registration, hit a fault, and left.
When I got there, the dash was showing "Key not detected" no matter what. The previous attempt had left the smart key ECU in a locked state. Board number 89990-0E031. Once that module locks from a botched write, it will not accept new key data through the OBD port alone.
I pulled the smart key ECU from behind the glove box, brought it to my bench setup in the van with the ACDP programmer, read the 93C86 EEPROM, cleared the fault data, and rebuilt the key registration table clean. Put the module back in, ran the full programming sequence through the diagnostic port for the HYQ14ACX fob. System accepted it first try.
Then the usual walkthrough: all four buttons, door handle proximity on both sides, hatch release, push-button start from the driver seat and from the passenger seat. Everything responded.
Whole thing took about 90 minutes, most of that on the bench work. The body shop had already been quoted a flatbed ride to the Lexus dealer and a multi-day wait. This got done same afternoon for a fraction of what they were looking at.

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”
