Subaru Problems? Ask a Mechanic for Answers ASAP
If you disconnected the battery, then you have to reset the security system. To do this, disconnect the negative battery cable, then turn the ignition to the on position and reconnect the cable. Then turn the key off and back on. This will reset the system.
Or if you have the key fob for the door locks, just lock and unlock the doors, this will also reset it.
