Hijacker is a vehicle hacking upgrade in Watch Dogs 2. It allows the player to hack vehicles' electric locks instead of lockpicking, so the player will not attract any attention when stealing a vehicle. Without this upgrade, the player will just pick the lock of a vehicle, causing its alarms to go off, which will result in a heat level. This upgrade costs 4 Research Points and requires the previous hack, Vehicle Directional Hack, to be unlocked. It unlocks Chopper Retreat Exploit.
