This post is fantastic, but unfortunatly I lost BOTH keys. I was told that security module and engine module have to be replaced. Is this true? Because it will be more than 2000$ !!!!!!!

Any idea?

Thanks

My understanding, based on the documents that I have for the European Yaris, is that if you lost all keys, just the the Certification ECU needs to be replaced.
