Any one know any thing about the above mentioned security systems? I disconnected my negative battery terminal, and it has meesed up the alarm. The car has a clifford concept 600 alarm and a MI600 immobiliser. After disconnecting the battery terminal, i can no longer lock/un lock start or do any thing with my car and its now P***ING me rite off. I have tryed every thing in the owners manuals to no avail. This is extremly annoying. Any one got any suggestions that may help?

 

did you try reconnecting the negative terminal? none of the cars systems will work if you dont have the battery connected.
