Santa Fe 2013 question - keyfob/security system issue

I have a 2013 Santa Fe Sport. My security system or keyfob are having a problem. Sometimes my car will lock, unlock, flash lights, etc. continuously when I stop and get out of the car. When I get back in the car, it stops doing it. Today, when I got out of the car, it locked on its own and I can't get the key fob to unlock it. The car isn't responding at all. Do you think it's my keyfob or something wrong with the security system?

    If you haven't already fixed this - I'd start with the simplest thing to do, replace the key fob battery, (make sure the new one is fresh) - along with that easy process I'd try the 2nd key fob, (also, with a new battery) - all the while keeping them away from each other AND the car, -meaning Physically away-, out of range -of the vehicle and each other AND the car.
    There is a slim chance that some sort of electrical interference could cause this to occur – If it happened after the installation of a new electrical device in the vehicle- such as a aftermarket charger for portable devices, or some such other device. I’d also check the cars battery and its connections, a poor connection there could cause interference and sporadic current flow. Barring these few items, it’s off to the Hyundai dealership- they’ll have the necessary and proper tools to diagnose this, hopefully. Hope this helps ….

    Do you have more than one key fob? If so, pull the battery from the one you usually use, then wait a couple minutes and try to access the car with the other fob.
