Cheers M8. That link for Michaeld's Button Flip Key guide is a life saver.
Fixed it already, the button was a doddle to solder back on, needed girlie to hold it down tho. Then a bit of fiddling to get the clip back on and its as good as new, took a few attempts to get it right but its working now.
Thanks again
One intresting thing to note, if you let the alarm go off when the engine is running it stops flashing the hazard lights and sounding after a couple of mins. Embarasing tho :/
