The Hyundai Smart Key fob is featured on many of the newer models we have on-site here at Van Hyundai. It's a pretty simple concept, but it provides you with excellent convenience. When you're away from your Hyundai, you'll be able to lock your doors remotely, unlock them, start your vehicle up ahead of your arrival, and there is even a panic button that can save you in an emergency. After you learn how to use your smart key, there may come a time when your vehicle isn't recognizing this technology. A little bit of troubleshooting can get everything functioning again.
