I use my remote and the horn beeps twice like it is locked but the doors will not lock ,also they will not lock when I use the switch inside the car the red light used to light up on the lock switch but does not anymore ?also the windows have been acting funny sometimes , they will go all the way up even with the top down ,and somtimes go up or down by themselves ?I do not know if this has anything to do with the locks not working ?
