My wife's 2002 Rav4 has its alarm going downhill. We've been operating without the original keyfob for ages. Now we only lock / unlock doors with the key in the door. Recently, EVERY time we unlock the door and open, the alarm goes off. Doesn't matter whether the red alarm button is in or out. Is there ANY way to completely disable the OEM alarm? We don't need it and we don't want it. Any help is appreciated.
