Faulty Key Battery Low message

My focus was AT the Dealer for an oil change on Thursday. When I picked up the car I noticed that the "Key Battery Low Replace soon" warning came on when I started the car. Tried both key fobs when I got home and am getting the Same message with either one. Replaced the battery in both key fobs but I am still getting the same warning.

looks like the Dealer must have done something when they did the Service.

Is there a way to Reset this message? Has anyone Else had this issue?

Since changing the batteries in the keyfobs didn't get rid of the message, I decided to disconnect the battery yesterday. I disconnected the positive terminal for a couple of minutes and then reconnected it. The message is now gone and everything is working correctly.
