Q: My car alarm no longer flashes when activated

asked by on

I own a 2004 Subaru Impreza WRX. The alarm no longer flashes when activated. Would replacing the Security Unit Module fix this?

Hey there, thanks for writing in about your 2004 Subaru Impreza WRX. If you replace the security module, it will most likely fix your the alarm, but you will need to reprogram the keys to get the new alarm to recognize your old keys. Get in touch with a local Subaru dealer in order to verify which component should be fixed.
