2020 tacoma can i add another keyfob with techstream?
My truck doesnt use an actual key its the push to start button, also my doors unlock when i pull the handle when the fob is in my pocket.

Also if i can do it with techstream can i use the aftermarket keyfobs from china, as long as its the same board inside and its never been programmed, or do i have to buy a genuine toyota oem keyfob???

thank you for clearing this up for me, i have techstream and i know there is a section in there for keyfobs but i have never tried it.

thanks

Yes to both. Here's one I programmed successfully as I lost the second.

I actually popped it open and the board inside is exactly the same as OEM.
