I got my second key from http://www.importmonster.com.au/order_view?id=23879 when it arrived from Japan put the internals into http://www.ebay.com/itm/170871691770?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649 http://www.aliexpress.com/snapshot/252972751.html First check that the key fits into the ignition switch, if so ...get it cut, then program it to the car. Any M35 key will program to the car. I also only recived 1 transponder for the immobiliser that was installed, however paid for one to come from England with details on how to sync both to the system and now everthing is good with 2 sets. If details are needed PM me.
