I have a 2004 Sienna LE. One power door.

How do I program the remote to unlock all doors when you hit unlock once? The manual says it's possible but "see dealer".




I found instructions online for other functions but can't find how to do this. I already set it up to lock the doors when you shift to drive and unlock when you shift to park, nice features.

Here are the instructions from my 2007, hope this works

#1 if it locks when gear is switched out of park
close all doors and turn ignition key to on position
shift the lever to P
within 10 seconds of turning the ignition key to the on position, press and hold the driver sides power door lock switch in the lock position for 5 seconds and then release.

#2 if it locks at a certain speed
key on
shift to N
within 10 seconds of turning the ignition key to the on position, press and hold the driver sides power door lock switch in the lock position for 5 seconds and then release.

If you hold unlock on step 3 for either, you can set it to unlock all doors when moved to P or key is removed and driver door opened.

I tried this in my 2010 Sienna but it doesn't work. Are there any other instructions for this? I have an LE with two power sliding doors.
