Driver Side Door Entry Unlock Function does not Operate: Description
WARNING: This page is about a different car, the 2011 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
If the driver door entry unlock function does not operate but the entry lock function operates, communication between the vehicle and electrical key transmitter is normal. As a result, the touch sensor circuit can be considered to be faulty (certification ECU (smart key ECU assembly) → driver side door outside handle → driver side door electrical key oscillator).
