    So I've got a question about this. I have 2 smart keys, but my wife lost the aux key on one of them due to the little "lock clip" being broken. If I order a new smart key, will I still be able to program it without card #2's aux key?

    your post in confusing. did she lose the smart card or the aux key? If you have 2 working smart cards, ordering an aux key is no problem. In fact they usually can match an aux key to your ecu's programming number (should be in your new car paperwork) .

    Sorry, I thought it was clear. The key (blade) itself was lost, because the retainer clip in the fob broke. So another aux key isn't really an option since it will just fall out unless I tape it in or something. I'd like to just get another new unit altogether, since that one was flaky to begin with.

    Ok I get it now. Yeah if you are wanting to get a new smart card, and the existing one still works, and you have 2 working smart cards, you can buy a smart card on ebay and program it yourself. I reccomend keeping your broken smart card somewhere safe for those "just in case" situations like if you loose one of your other cards.

    I bought a 3rd used Smart Card (a good deal), but it does not have a Aux/proximity transponder key. Those I see on Ebay have blank aux keys but they are chipless and useless as far as I am concerned. I found a couple of dealers online who have transponder keys available but they do not ship to Canada. Does anyone here know of a dealer who is either in Canada or willing to ship here from the States? Thanks in advance for any help you may be able to offer.

    Both of the smartcards I bought on eBay were new Mazda cards, but the aux keys were knockoffs. However, both the knockoff aux keys had rfid chips inside them. Unfortunately one was only held in place by one drop of glue and it fell out. Are you sure none of the blank aux keys on ebay have rfid chips? I'm sure not only have I seen solo knockoff aux keys with rfid chips inside them, but I'm sure I've seen folks selling oem aux keys on ebay.

    Wow quick response thanks. I only found a couple of guys on Ebay who are selling aux keys and neither of them have transponders in them since I did in fact message them to know for sure.

    Is the procedure for the 2011 CX-9 the same as the 08-09s for programming the fob (not the key blade)? My wife's keys ended up in the microwave and came out a black smoking/melted mess...long story. Needless to say the key blade still registers with our 2011 CX-9 but the fob was burnt toast (literally). I acquired another fob but noticed the new fob is a mitsubishi electric remote and the acquired older fob is a siemens production.
    I tried the programming from the earlier post but do not get the confirmation from the vehicle (lock/unlock) that it is in programming mode.

    Any advice is appreciated.

    Flymhi...wow microwaved! When programming a new fob, you have to have 2 other working fobs present. If the fob that got zapped was the 2nd fob, you will have to go to the dealer to have them program the replacement fob, they will charge you an hour of labor.

    No. As for "programming", the ID in the keycard is made to be "remembered" by the car's ECU.
    The ID is unchangeable in the kaycard. Changing battery should not alter it.
