Hello! I have a 2005 Civic EX we just bought. I'm so new at this forgive me...
The alarm goes off on it's own. How can I tell if the alarm is factory or after market and most importantly can I disable this alarm for good? If so, where should I begin? I want it disabled for good (also heard that can cause issues).

Any and all advice and help is more than welcome. Thank you so much.
