Front Passenger Side Door Entry Lock 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 front passenger 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†’ passenger side outside handle (entry lock switch) โ†’ front passenger side door electrical key oscillator).
