    Exclamation Programming 2004 CTS Fob

    Hi guys,

    I recently bought 2004 Cadillac CTS (4 doors) and it didn't have a remote control key (fob, that just opens the doors when in few meters away). The guy who sold me the car, gave a fob, he said that it's not from this car, but it's for CTS and I can google it and program myself. I found online that dealerships will charge me around $60 for doing that and wanted to do it myself as the process shouldn't me hard.

    I found couple posts where someone said that you have to put the fob in cup holder and turn the key at the drivers side 5 times within 5 seconds and the car should show me something about the fob in the screen - but it didn't really work.

    Am I doing something wrong or is it wrong instructions?
    How to do it myself?

    Thank you in advance

    FOB needs to be programmed by the dealer with a tech 2

    the key however can be programmed yourself but not the fob.
    CTSM and Ikera like this.

    Program the key...? I don't really know what that means....
    So there's no way I can do everything myself and those instructions are false..?

    yes, the keys these days are not just pieces of metal, the have a chip transmitter build in that needs to be recognized by the car. So if you cut a new PK3+ key you need to have it programed otherwise you won't be able to start the car with it... instead alarm will be activated. The new cut key can be programed by the car, however the Fob needs to be programed by Tech 2... and I think dealer is the only place that can do it
