Flashing lights when alarm is set
 

I own a 2006 Santa fe. Recently I noticed that the lights no longer flash when the alarm is set. Is this a weird programing thing that I can fix myself or should it be taken to the dealer?

If the lights aren't flashing then the alarm is not setting. My guess is, one of the doors, the hood, or the hatch isn't fully closed (or the sensor is bad).
