Hi Romasato, That is some excellent information! Thanks very much. I shall check my keys and see where that takes me. Ill keep this thread updated. Thanks Mobi

Hi all, Our Rx400h only came with 1 master + 1 key shell only (no internals). So I bought an aftermarket key 4d67 from ebay and managed to programme the central locking with Techstream but the immobiliser will not programme. Getting error saying "the communication error occurred between the key and the ecu". I can only imagine that this is as it is not a genuine key. Has anyone actually managed to programme a replacement key for the Rx400h? It seems to be difficult to find a used rx400h key, do we know if a used rx300 key will work? Or any other known models that will work with the rx400h? Or if anyone has any other ideas that wont cost the earth. Thanks Mobi
