Lexus Key & Security System Overview
Lexus vehicles use Toyota's Smart Key system with Lexus-specific calibrations. The smart key system relies on multiple antenna amplifiers throughout the vehicle, a certification ECU, and the smart key ECU to enable keyless entry and push-button start. We program Lexus smart keys using Toyota Techstream diagnostic software for all models including the ES, IS, GS, LS, NX, RX, GX, and LX.
