2004 STI Not Starting - Security Light Flashing
« on: January 14, 2018, 11:13:04 am »
Hey everyone. Yesterday I went to go start my 04 sti and the car alarm started going off once I opened the d/s door, waited for it to stop then put the key in the ignition and the alarms started going off again and would continue to do so everytime I turn the key in the ignition, preventing me from starting it.

I've tried disconnecting the battery, turning the key in the door multiple times, holding the unlock/lock button down on the inside of the door and nothing seems to work. The security light is flashing constantly and whenever I try anything, the damn horn just goes off - its just locking me out of my own car. The only modifications I have on the vehicle are a compustar 2 way remote starter and a double din head unit.

Any ideas/suggestions at this point would be greatly appreciated since Im clueless when it comes to electrical.

did you unlock the door with the key?

Nope, I used my remote to unlock the doors and that's when it all started

Use the subaru fob to unlock it, it'll disarm the OEM alarm. I removed my module from my 04 when I had it, as it kept arming when I was trying to get the remote starter primed, and it would set off my supertones at 9pm at night.
If the sea was vodka, and I was a duck.
I would swim to the bottom, and drink my way up.
But the sea isn't vodka, and I'm not a duck.
So give me the vodka, and stfu.
If you're having forum problems, I feel bad for you son, I got 99 problems but your post ain't one.

Where might I find this module? Unfortunately I don't have the original Subaru fob

It's between the front seats, under the armrest. There's write ups on NASIOC. It's been a long time since I removed it. It also doesn't disable central locking, which was a concern at the time.

did you cycle the system with the key? like turn the car ignition from On to off 5 times in a row? that usually also reset the alarm if i am not mistaken.
