Keyless entry is a standard feature on most vehicles produced today, including the 2002 Hyundai Sonata. The remote, powered by a small battery and synced to your vehicle, allows you to unlock or lock the car, arm the alarm and pop the trunk from a distance. However, if your remote is lost and you need to program a replacement--or if your remote is no longer synced with your vehicle--you will need to follow specific steps to reprogram it.
