Toyota Mark X 2005 Immo Reset (Key Lost - Non Smart Key)

[peter0991]

Hi all,

I lost my only set of keys last week and since then I have been trying to start my GRX120 Mark X Toyota. The model is non smart key version. I have removed the Immobiliser ECU (PN:89780-22020) and from what I could tell, read the chip (93LC66B). I currently dont have a new key, will I be able to start without a transponder?

I would be greatful if someone could have a look and help me out. Dump file attached.

So I tried to wipe the immo chip to read all 1's (FF). Got a new key to try, but still not managed to get the key registered and the motor started. Only two line in the bin file get updated when I connect the unit to the car
