The Remote Keyless Entry (RKE) receiving unit on certain Nissan, Kia, and Hyundai vehicles through 2017 allows remote attackers to perform unlock operations and force a resynchronization after capturing two consecutive valid key fob signals over the radio, aka a RollBack attack. The attacker retains the ability to unlock indefinitely.
