I have installed an Evo-one in a US version of a 2015 Subaru Legacy standard key with the T-Harness. The issue at hand is that the OEM keyfob will no longer open or close the locks if you delay your exit. If you exit immediately, the keyfob functions as normal. If you delay long enough that the interior lights dim to off, the keyfob will not lock or unlock the doors. The only way to make them functional is to put the key in the ignition and turn the car on and off and then immediately lock the car.
