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 new key registration warning message is not displayed after an electrical key transmitter sub-assembly has been registered, there may be communication problem between the certification ECU (smart key ECU assembly) and combination meter assembly (meter ECU).
