Lexus RX300 right rear door lock electrical failure and manual locking needed after setting alarm on Lexus RX300

Some Lexus RX300 owners report experiencing electrical failures with the right rear door lock, necessitating manual locking after setting the alarm. These issues may arise when the door lock does not respond to the key or alarm system, prompting owners to manually lock and unlock the door from the inside. Additionally, while some Lexus models feature remote locking and unlocking for the trunk or back door, this capability is limited to select model year 2022 and newer vehicles equipped with the Lexus Interface multimedia systems. Owners may also need to initialize the power back door system to ensure proper operation, which involves specific procedures such as using the door lock switch and fully closing the back door. Furthermore, some Lexus SUVs offer a convenient lock and walk feature for the rear door. If manual locking becomes necessary, it is recommended to consult a professional technician or contact Lexus customer support for further assistance.
