For some reason the horn isn't going off anymore when I lock/unlock my car. Anyone know what I can do to fix?

 

Have you checked your fuses? It could be the horn fuse or relay.... That's my best guess...

 

It's on your remote, push and hold the trunk and lock buttons at the same time until the red light goes solid and then goes off. Then try to unlock your car, it should work. Mine goes off all the time, so I have the movement permanently programmed in my brain

 

It worked!!!! Thank you so much. That was bothering me for a minute.
