Special Service Message 44428 2012-2014 Focus - Intelligent Access Key Battery Low Message Does Not Reset After Replacing The Battery - Service Tip
Some 2012-2014 Focus vehicles equipped with Intelligent Access Push Button Start may exhibit a Key Battery Low message that remains on after replacing the battery in the key fob. If this concern is observed, perform the following procedure that allows the vehicle to properly sample the key fob battery level. With only one (1) fob near the vehicle, start the engine. With the engine running, press the Lock or Unlock button on the key fob one time. Repeat this procedure with all additional affected key fobs. When the vehicle properly samples the new key battery level the message will no longer be present.
