Q1: Tried to do 2023 Toyota Fortuner H type 8A all key lost with Autel IM608 and 8A blade AKL cable. But cannot see the diagram for immo box (marked Y3). wiring diagram on autel is for a different box. The diagram is different from the old one (2014 to 2017).
Q2: working on a 2022 Hilux with all key lost, transponder key with h chip, tried with Xhorse key tool plus and 8A AKL cable, it does work. 89780-0k070 mark in the immo box Y3.
Is it possible to dismantle the dashboard and use a cable directly to the immobox with xhorse cable?
How to program 2020 and up Toyota H Y3 immo box all keys lost?
Autel/Xhorse doesn’t support that immo box as yet as you can compare diagram. It has lesser pins.
This is the third generation Immo box named Y3 and many others have no solution except replacement inside Immobox Renses MCU.
Y3 immo box on Blade key with “H” transponder can’t reset. Must replace with new virgin box from dealer and code the transponder.
This kind of immo box has blade key transponder type and smartkey ecu is large in size.
Hilux and Fortuner Y3 immo box need to replace immo box. Y3 immo box must be replaced.
Cannot be done by Auteo IM608, Xhorse, OBDSTAR etc. C8 can’t too. No tool can read that Immobilizer it is encrypted, only solution is to buy new Immobilizer and program the key.
Cannot be reset. Need new immo box.
New IMMO BOX comes with a re-program transponder chip.
Have to change the immobox.
Add a key.
Then active tc terminal.
