Hey everyone, I am a new member of these forums and I just had a question in regards to the third party security system installed in my 1998 R34 25GT Sedan. As far as I know, there is a security system installed on it but I do not know how complex the system is and whether it has an immobiliser on it. I know the alarm isn't working because the LEDs do not turn flash when the engine is turned off. This is may seem like a stupid question but who could I go to get it fixed?
