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

WARNING: This page is about a different car, the 2011 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.

When the wireless door lock and unlock functions operate, the communication circuit between the door lock receiver assembly and certification ECU (smart key ECU assembly) is normal. When the entry lock and unlock functions do not operate, radio wave interference, a customized entry cancel function, or a communication error between the key and vehicle in the smart communication circuit, is suspected.
