All Door Entry Lock/Unlock Functions and Wireless Functions do not Operate: Description

WARNING: This page is about a different car, the 2010 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

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