As I recall the gentleman making the duplicate chips for the side mirrors is still doing this, and I am sure I saw some ads for this recently, now I cannot find them. Hopefully he will send you a private message.
As for the discussion about these not working, I think that some 'duplicators' were using old cards from people that no longer lived here, and these were removed from the system, therefore the copies would no longer work.
On a side note, I have been testing various gates and it seems the new readers easily read the cards through a CLOSED car window, and I have several other cards in the wallet.
