All Door Entry Lock/Unlock Functions and Wireless Functions do 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.

When the entry functions and wireless door lock functions do not operate, a malfunction or wave interference may be occurring in either of the following: 1) signal communication between the door control receiver and certification ECU (smart key ECU assembly) (communication shared by entry and wireless functions); or 2) electrical key transmitter.
