Additional Key cannot be Registered [06/2018 - 09/2022]: Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus ES 300h, 2023 Lexus ES 300h, 2022 Lexus ES 300h, 2021 Lexus ES 300h, and 2020 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

If additional registration is not possible, a malfunction of the electrical key transmitter sub-assembly, certification ECU (smart key ECU assembly), power switch, No. 1 indoor electrical key antenna assembly (front floor), steering lock ECU (steering lock actuator or upper bracket assembly) or door control receiver is suspected.
