Touching Unlock Sensor for Certain Period of Time does not Unlock All Doors [10/2018 - 07/2022]: Description

WARNING: This page is about a different car, the 2022 Lexus UX 200, 2021 Lexus UX 200, 2020 Lexus UX 200, and 2019 Lexus UX 200. However, it is still accessible from the selected car via links, so may be relevant.

If the entry unlock function of the driver door cannot be operated by touching and holding the unlock sensor of the driver door, but can be operated through other methods, it can be determined that the request code is being transmitted properly from the driver door. In this case, the certification ECU (smart key ECU assembly) may be malfunctioning.
