Information Only. Here we share a customer’s working experience on a 2022 Toyota Rav4 USA model.
2022 Toyota Rav 4, USA, Add Smart key. He has a working key to start the vehicle. The new key was a brand new OEM smart key.
First try the UHS Toyota bypass cable, by connecting G box right into the smart box. But did not get any communication.
Second attempt: He then notice that the Autel IM608 had an update for Toyota dated Dec 19th 2022. He performed the updates noticed that after the update it said Back Up IMMO date via OBD, or VIA G-box , he tried G box again and No luck, keep saying no communication to check cable turn off Bluetooth check power etc.
Last try: So he put it all back together and then decided to try to back up IMMO via OBD. G box Was not needed. Connect right into OBD 2 port. It did back up the data, So went into key learning, follow the steps, it asked if back up, clicked yes, and it went into learning mode. And successfully learn a New key via OBD II without doing a In-code or out-code, or any Password, or paying any $30 fee. (You would typically need a in-code & out-code password, just to add a key fob, and would need to pay $30 for the third party service. But this time does not need.)
The new update says in the update that it supports up to 2017. But still worth trying.
