Rear Door RH Entry Lock and Unlock Functions do 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 lock and unlock functions do not operate for the rear door RH only, the request code may not be being transmitted from the rear door RH or the rear door outside handle assembly (for front passenger side) (touch sensor) may be malfunctioning. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and electrical key and tire pressure monitoring system receiver assembly is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and rear door outside handle assembly (for front passenger side) (electrical key antenna)), or there may be wave interference.
