I have a scion tC 2006 and im installing my alarm and i have seen it on here before but i cant find it anymore. But i was wondering how would i set up a set up relays unless theres and easier way to unlock both doors. with the stock keyless entry you press the unlock button twice to unlock both doors. i was wondering if anyone can help

whats your alarm unit? most units offer double pulse unlock to open all doors. if not, you can use a relay and a capacitor to mimic the double pulse if your alarm unit does not offer it. follow link below
