Driver Side Door Entry Lock Function does not Operate: Description

WARNING: This page is about a different car, the 2012 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

If the driver door entry lock function does not operate but the entry unlock function operates, communication between the vehicle and electrical key transmitter is normal. As a result, the entry lock switch circuit can be considered to be faulty (certification ECU (smart key ECU assembly) โ†’ driver side outside handle (entry lock switch) โ†’ driver side door electrical key oscillator).
