We checked the Key two different ways, firstly we checked the 433Mhz RF characteristics and after this passed (we could see noise on an SDR) we tried to read the ID from the key using a standard RFID reader. The key did show some signs of physical distress, at one point during the transplant the key was in the barrel and did experience some impact but I thought it was a negligible amount and not enough to cause a failure, especially not of the transponder internal the key. Actually it wasn’t even on our to-do list to check the key, nothing really pointed at the key failing but my buddy Duncan had an inclination it was at fault so took it to his lab to check it.ĭuncan runs Fobfix and specializes in key repairs and programming so it was lucky I ran the problem past him.
DebuggingĪfter a serious amount of head scratching and ensuring each wire was properly reinstalled we decided to test the key. I was able to pick up a damaged Ion for ~£2000 which is a fraction of the cost of an electric drive train and I was able to break the car for a decent return on my spend. I could of course have bought an entirely new Electric drive train setup but my goal here was to learn from others and reuse existing electronics so avoid them landing in the scrap pile. I had everything working after being stripped from the Ion then once I had transplanted the items into the 205 nothing worked.
I am transplanting a written off Ion drive train, ignition barrel, batteries et al into a Peugeot 205. Do not think of the Ion or C-Zero as a Peugeot or Citroen, I have had countless offers of people saying they can help but not really understanding the entire car is built by Mitsubishi and as such any knowledge of other manufacturers implementations is irrelevant. This is in contrast to Peugeot and Citroen who usually do. The remote locking part operating at the UK standard 433.92Mhz and the immobilizer implemented using the standard 125khz RFID “barrel ring” setup.Ĭontrary to popular understanding Mitsubishi do not include transponder data in a Body Control Unit (BCU). The vehicle we worked on had an industry standard RKE implementation. The car has a relatively standard security implementation. The Peugeot Ion AKA Mitsubishi i-Miev & Citroen C-Zero is an electric car that was built for both Peugeot and Citroen by Mitsubishi motors. I appreciate most readers wont expect me to publish a failure story but a huge amount of time I spend working on projects is failure after failure, without writing the failures down myself and others could replicate the failure and that’s not a good path to progress. I will hopefully explain a bit about the security architecture and I will also my discoveries and some “pro tips” for not getting yourself in the same pickle as me. In this post I’m going to document our attempts and ultimately our failure to clone a Mitsubishi i-Mievs Immobilizer system EEPROMs from one car to another. Duncan runs Fobfix and if you need an immobilizer fix, replacement key or secondary key you should definitely check out Fobfix’s store. This was a journey I went on with Duncan, Duncan deserves the props for the technical understanding of the car security, I was just the wrench monkey and author.
