I have a terrible fear of my imobilizer operation as having brought my MG F as a barn find and it cost me more than the car to get around the issue of not having the imobalizer fob. I eventually found a wizard that was able to get around it but he is in Australia.
I have seen this kit online (from WA in Autstalia) and will probably go down this path as car theft issues have been ameleoriated by evolution here in Australia. Most car thieves here are adolesent and usually only steal top of the range new cars and would think a manual car is a book.
