Hello everyone,
talking about a late 70 series:
I lost one key.
So I bought a new original transponder and had it cut (not the wireless kind, just the "classic" Toyo key).
It opens the doors etc.
Now, I would like the lost key to be deleted from the immo ECU and the new key to be accepted.
So far so good.
Here comes the questions:
It seems the designated procedure would not be to delete one key and add another, but to delete all keys and add all existing.
I have seen some tutorials here on mud, tlcfaq, etc for vehicles decades old, where you could do some combination of opening / closing the doors, depressing acc. pedals and so on. But that seems not to apply to the late Toyota/Lexus vehicles anymore. I tried some of the procedures, of course they didn't do anything.
The official procedure, I figured, would be to visit any Toyota dealer who then deletes all keys and re-programs them.
For that they would need a special code from Toyota HQ, that they would get by sending in the VIN or something like that.
All in all it will be costly.
I have also found a procedure to read the contents of the Immo ECU flash chip, edit the data dump, write it back to the chip, get the immo ECU into auto-programming mode and then add all existing 3 keys. It's complicated, thus costly as well.
Is there any old style procedure to achieve what I want or do I have to throw money at some Toyo dealership?
