Gemini 7200 car alarm replaced battery fob not working no tx to alarm.
please help and many thanks.
The problem seems to be the key fob on these alarms goes out of sink with the alarm unit (thats if you have changed the battery and its not responding), but 7200/7300 have the ability to "self learn" the new frequency your key fob has changed to .I dont know why they change frequency but they do.I have had to do this a few times myself. if you have a manual for this alarm it tells you how to do it in there but you will need the round key that comes with the alarm that fits in the top of the alarm unit (siren). Anyway to do it : 1.using the key switch alarm off. 2. switch on again. 3. turn ignition for 1 second then off. 4. push the key fob.within 30 secs. 5. switch dim dip (6) back to off. if it dosent work repeat.(dim dips are in the siren where the wire goes in) and if the alarm goes of while your doing it dont worry but just try and be quick. Hope this helps. Chris 13.
