I got a Toyota Roomy van with one key, the second either remained in Japan.
I’ve been planning to fix this for a long time. And I ordered a key and a mini vci Toyota techstream cable.
The key must be new or blank. To register the key you need to prepare a laptop with Techstream installed, a mini VCI cable, an old key and a new key.
I registered with Techstream version 16.20.023.
Then the program will ask you to bring the old key to the start button – if the central lock clicks ok, then the new key. These operations take 30 seconds. – you need to have the keys in direct access. )
Everything, the new key is registered, it remains only to cut a new physical key on a blank.
