Well i bought a 98 legacy GT but i guess i set the alarm and know the immobilizer is not letting me restart the car and i dont know what to do. If someone could tell me on how to get around this or fix or something i cant drive my car and i am getting very upset i tryed to reset the car but disconnecting the battery but that dont seem to work but let me know asap

 

Disconnecting the battery will automatically set your alarm off, so that's not gonna help any. I would look under the dash and hope that the installer didn't find it too necessary to hide the brain and the cut-off relay too much. I would suggest pulling the main fuses from the alarm brain, they should be very close to the brain. If that doesn't work in and of itself, you'll have to find the cut-off relay (hopefully around the main ignition harness in the vicinity of the steering column under the dash). When you've found a relay that is obviously not stock, try unplugging the ground wire and the trigger wire to that relay and see if it will start then. Take note of the wire positions......If that doesn't work I would advise you to put the wires back how they were and tow your car to an install shop and see if they can either get you a new transmitter or remove the offending alarm from your car.
