How do I program keyless entry to open all doors on 1 click

2009 Access Cab.
I've searched this forum and have found solutions for unlocking both (or all four) doors with one click of the remote.

I've been opening and shutting the door and pulling the key in and out per the instructions but nothing has worked.

Have the official 2009 instructions for this been posted somewhere? If so I can't find it so please tell me how to do this.

Thanks

 

All of the directions you'll find are intended for first generation tacomas with a different alarm system / body ecu.

Unfortunately there is no way (that I know of) that you can change the keyless system in 05+ trucks to do this.

 

I've been searching for over a year much to no avail. Sorry.

 

I put a compustar starter in my truck at the dealer, and this fob unlocks all the doors with one push. something to consider? The starter is great!
