No service or anything done to my car recently but overnight, my Subaru Forester 2018 OEM push button remote start stopped working. Tried replacing the battery, no change. Doesn’t matter the distance, I press twice as I always did and the remote blinks green and doesn’t start. Not in service mode or anything, I think it may have lost its programming somehow. Now I don’t want to pay $70 to have it reprogrammed at the dealer, can I do this myself?
