I have two key fobs .. one is synchronized and the other is not. When I hit the big button on one of my key fobs both the red and green lights under the rear view mirror flash for 30 seconds. I checked the batteries ... they were ok .. I tried synching per the manual .. nothing. I changed the two batteries .. tried again .. nothing. I stood outside the vehicle and pressed big button twice, then within 30 seconds opened the door and then inserted the key to position two on the ignition switch ... per the manual .. nothing. Fob did not synch.

Does anyone know how to synchronize the key fob on the infra-red 96'E320 -- frustrated in FLorida ...carlos
