Driver Side Door Entry Lock and Unlock Functions do not Operate [08/2019 - ]: Description
WARNING: This page is about a different car, the 2022 Toyota Sequoia, 2021 Toyota Sequoia, and 2020 Toyota Sequoia. 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 driver door only, the request code may not be being transmitted from the driver door or the front door outside handle assembly LH (touch sensor). If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and door control receiver is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and front door outside handle assembly LH (electrical key antenna)), or there may be wave interference.
