I must admitt, it took a few times for me to understand you. Not to be rude or anything.
But anyways. It sounds like you learned the codes wrong. What you must do is to set up the remote to learn. Push the button in which you want to learn. When it say it's learning. Push the button on the orgianl remote. But you must hold it. Until the remote beeps and says "ok" Or whatever it says when the code has been learned. Then the code should seem shorter. The resason why them seem long now. is because they might be a dirty code.
