Test every registered transmitter to confirm correct operation. ! Deleting old transmitter codes The control unit of the keyless entry system has four memory locations to store transmitter codes, giving it the ability to operate with up to four transmitters.

You can set the system for deactivation yourself or have it done by your SUBARU dealer.
