My cousin just installed some new sounds for me and I dont know if he did something wrong but there are 3 buttons on my keys: lock unlock and alarm. Before he put the sounds in there the alarm button worked fine and the lock button made a beep noise when i locked it. But it dosent do it anymore. The alarm dosent work period and the lock dosent make the beep sound anymore? the question is how do i get the buttons back working like they use to?
