Hi all, new to this forum , hope it’s kinda than when I owned a Citroen Picasso grande!! Awful car . Anyways, we purchased a c max grande as we couldn’t quite afford the s max. 1.6 diesel manual. Two key fobs . Two weeks ago we went to open car with kids in tow, and nothing . Welcome to the shock we had when we then realised we had no key to open car . Ah, there is, inside fob. That was ingenious ! Then find that fob will still work by placing it next to where key would be in car. Amazing. Then after scrolling net to find out how to get battery out, we replaced from Halfords . 2 days later , no ford key detected . So hold fob next to where key would go , and all good. Must have been bad batteries . So buy new ones . All works . Week later, no ford key detected . Ok, either I’m buying dud batteries , or something is a miss here ? Help!!
