How do you restart your Subaru legacy security system?

Answer 1

Ok, try this.

Put the key in the ignition, and turn forward

all the way just before cranking. Then within

5 seconds, locate, press and hold in the

valet/overide button, found under the

dash area, (push button, spring loaded)

until the installed LED (the blinking light)

in your dash area goes on solid,

and the siren chirps once.

(Your valet switch might be the toggle

(on/off) type. in this case, key on,

flip switch in opposite direction,

then turn the key off.)

This should reset the alarm, and reset

the grounded relay on the starter wire,

allowing you to start the engine.

At this point, the only thing working would

be the keyless entry from the alarm,

if it came equipped that way.

Just Repeat these steps to place it

back to usable armed mode.

You may get 2 chirps, confirming it,

and the lights may flash twice as well.
