Each CAS will only work with 6 sets of remote key, we are having 2 when u take delivery of the car, 4 more is kept somewhere else, locked away. So if you lost your remote key, u can seek replacement from SC and once the 6 remote keys are used up, the old CAS needs to be replaced to make way for 6 more remote keys.The CAS is talking to both your remote key and unlocking the ECU as part of the immobiliser system. Your car won't start without a proper CAS, initiated by an authorised remote key. Our car cannot hot wire. To put it into simpler layman terms, the "code word" mentioned by Schwepps above is like our usual internet password verification questions.. i.e. What's your favorite pet? What's your mother's maiden name? and the like. CAS will be responsible to ask those "questions" and our remote key is responsible to "answer" with its so called "code word".. and the question keeps changing. Without the proper "answer", our ECU is locked and car won't start. Now u know why its impossible to duplicate our remote key.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /></blockquote>
