What are some of the hyundai elantra security system problems?

If the security system is not working in your Hyundai Elantra the first thing that you should check is the battery in your key fob. When this starts to die it can result in the alarm not being able to arm and disarm using the fob and that can lead to problems. If you have replaced this and are still having problems with the alarm then you may need to go ahead and try to reset it. Usually resetting the alarm can clear up a lot of the problems. If a reset does not clear it up then the next thing that you will want to do is go ahead and take it to a dealership to allow them to inspect the body control module for any faults.
