Child safe lock missing from Toyota Sienta / Sienna : workaround for mentally deficient passenger

Just take delivery of Sienna hybrid & realized it doesn't have child-safe lock like Altis & Airwave.

My intellectually disabled autist teen son tends to open the door whether it's in motion or at
traffic light.  Is there any way to go about this so that in the event there's nobody sitting at
the back with him to watch him, there's a safety measure to prevent him from opening the
passenger door

What year is this.. 2016+ Sienna's come standard with child safety locks

Ask your dealer how to use these locks. Childproof read door safety mechanisms have been around for decades on most cars and vans. It may be a mechanical lock, but it will be there.

Have a look at this  and see if these instructions help.  I am presuming that the Sienna does have child locks.

I did specifically ask my dealer: he said only when in motion  you can't open the door:
yes, you can't open door when in motion but when almost stationary or stopped at
traffic lights, this 2017 Sienna's hydraulic passenger doors could be opened.

For sure the dealer & I searched for that little child-safe lock plastic button : it's
not there.  I could not locate the button in the link from dbrunton

Bummer!  My child locks are levers. Engage them and the back doors cannot be opened moving or stopped.

Check with the dealer and see if they can retrofit the locks described in the link I posted.

Dbrunton's link helped: it's there but in complete black color & at a lower position.  Thanks

Thanks for the update. I thought it should have been as the locks have been around for years.
