All Door Entry Lock/Unlock Functions do not Operate, but Wireless Functions Operate [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.

When the wireless operation can be used to lock and unlock the doors, communication between the electrical key and TPMS receiver assembly and certification ECU (smart key ECU assembly) is normal. If the entry lock and unlock functions do not operate, the entry cancel function may be set through the customize function, there may be communication problems between the electrical key transmitter sub-assembly and vehicle, or there may be wave interference.
