Stock alarm

[mr_g]

I am using my stock alarm on my 98 Subaru Legacy GT 2.5 and I wanted to know how to I make it so when I press the unlock button on my keyless entry it will unlock all my doors? As of now whenever I press on the unlock button it just unlocks the driver door, which bothers me when I have 3 other guys waiting on the doors to unlock. If possible can you unlock the driver door by pressing it once and the second time it unlocks all the doors?

Hold the unlock button down and it will unlock all your doors.

You have to press unlock 2 times to open all 4 door. When you press it once it only open the driver side door.
