keyless entry has always worked great, well.............. we take her mp3 player and fm transmitter along on a short trip yesterday and while trying to get it to play over the radio the door locks clicked like someone had locked them with the keyless entry. I was pressing the select button on the mp3 player when it made this noise. Well later when we stopped the remote my daughter had wouldn't lock the doors. Initially we thought it was just her battery getting weak or gone dead. Checked mine too, it also would not work. Anyone know why this happened and if there is an easy fix for it?
