Key fob battery message

Recommended Posts

Hi,

      My wife has a cmax 2011. It has the push button start feature. She had a message pop up a couple of weeks back saying key fob battery is low, please replace. I changed the battery for a brand new one, yet the message is still there two weeks later. Do I need to do something to make it register? I was under the impression that it'd detect it had a new battery and dissappear. 

Any ideas on what to do?

Thanks very much.

Heard a few people with this problem. Some have said they have taken the car to Ford and there is a BCM update that cures this, I'm not convinced that that is nothing more than a money spinner for Ford. The two other methods I have come across with good success rates are easy fixes. First try this, start the engine and with the engine running press the lock button. If that doesn't work then disconnect the positive lead from the battery for 3-5 minutes then reconnect and all should be golden! It's a bit like when your computer doesn't something weird so you 'turn it off and on again'.
