Ive got a cliford alarm on my cossie and there is a piece of paper holding both the batterys in the key fobs. The metal battery connectors have come away so with out the bits of paper the alarm wont arm or disarm. Then there is the main alarm ecu which the connector keeps coming out of so that again the alarm wont disarm. But apart from that is a good alarm. Its also got a turbo timer that works off the key fob.
