You could get a PAC TR-7 module and set it up in Mode 4 to take the add-on units single Unlock pulse and output a double pulse. That PAC TR-7 output connected to the Sienna's Blue Disarm wire will get all the doors unlocked with one code entry. PAC TR-7's can be had for $12, delivered, off EBay.
Here is a link to the PAC TR-7 install guide : https://www.the12volt.com/installbay/file.asp?ID=1031

Before you posted this, I ordered a Directed Electronics 452T. It was $10 shipped from the usual source. Not sure when I'll work up the motivation to hook it up and try it, but I'll report back when I do.

The 452T is another option. Not sure what it's idle current draw is, so you might want to check that out. Everything you add to the vehicle uses power and you don't want your car battery going weak in a few days of non- use.

Thanks again for the info and this pic. I started to install today, but for the life of me I cannot get to the wiring harness in your pic. Did you remove the plastic housing around where the fuses are? Or did you loosen the body ECU and rotate it?
I am assuming this pic and the work was done from underneath th dash.
thanks!

Yeah, you do have to do some disassembly. Check this post for instructions:

BTW, about a week ago, I discovered there is still one glaring problem:
If you lock the car with the keypad, you cannot unlock it with the keypad. Locking it with the keypad requires my 6 digit PIN plus pressing 3/4. That's a pain, so I never did it. The only way I discovered this was by re-locking it by accident when I was trying to unlock it. I have since disconnected the lock pin so it can't happen again.
For problems like this, I hide a key in a magnetic box under the car.

Sorry to bug you again, but there are several blue wires in the 30 pin harness. Can you tell me which one is 24?
thanks!
