Front Passenger Side Door Entry Lock Function does not 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.
If the front passenger door entry unlock function operates normally, but its entry lock function does not, this means that the request code from the front passenger door is being output normally. In this case, a malfunction in the lock sensor circuit (from the certification ECU (smart key ECU assembly) to the front door outside handle assembly (lock sensor)) is suspected.
