So I have all my keys for my 2011 Legacy 2.5 base. My main key, only half of the alarm module works. The lock button works with no problem, but the unlock, trunk and panic stopped working. I have to press it a few times before it actually unlocks the car. Probably the board has some hairline crack, preventing contact? Replaced the batteries, no dice.
The immobilizer works fine. Just want to see how can I replace the alarm chip and program the new alarm portion to register to the car. Will that require the dealer to do that?
