I wonder if this works:

How to activate the automatic locking / closing of the doors on a vehicle: The lock button
The most basic method if you are in the event that your automatic door closure no more be effective, is to turn on the ignition (on some series you will as well need to have the engine running) and soon come and hold down the door lock button on your car for a few seconds until you listen to an audible alert and, dependent on the year of your Toyota Yaris, the turn indicators that are activated. This method should be good enough in most cases to activate the automatic door lock on your Toyota Yaris

Have you tried it Lauren ? I would like to activate this feature as well .
