lexus remote issue

This is Tasha again, thanks for the answer about the remote, I took the car and the remote to the dealer and was told that there must be something wrong with one remote because when they program the remote both are set the same way, he stated there is not an option to set one remote to beep and the other one not to (sounds kinda wierd to me).I even changed the batttery to see of that will solve the problem but it didn't. I just don't see why they are saying they both have to be programmed the same unless that is something that Lexus does.
