Rear Door LH Entry Unlock Function does not Operate [11/2021 - ]: Description
WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.
If the entry unlock function does not operate for the rear door LH only, but the entry lock function operates, the request code is being transmitted properly from the rear door LH. In this case, there may be a problem related to the unlock sensor (connection between the certification ECU (smart key ECU assembly) and rear door outside handle assembly (for driver side)).
