Only door that can be locked or unlocked using smart key or electrical switch is the driver's. Trying to open other doors using the smart key only produces multiple lock system beeps but door remains locked. Only way to open or lock door other than drivers's is the mechanical latch. Have reprogrammed the lock function using the owners manual procedure to no avail. Has anyone else experienced this situation and found a solution. Found similar situations with Toyota system by web search where passenger's door lock actuator was culprit but not here. Toyota dealers next try will be replacing the ECU.
