Default Key Battery Low reset?

Might be obvious but I was getting the message so popped a new battery in my remote but the message still shows on the dash after starting. I checked the resting voltage of the new battery and it's 3.4V so not a dud?

And yes, the battery does do what it's supposed to do since I can lock and unlock my car, which I was still able to do with the old battery but the message was annoying and thought best to change it anyway.

Could anything else trigger it?

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.
EFFECTIVE DATE: 04-MARCH-2014

Didn’t work for me. Only button that works when car is running is boot open.

I don’t have keyless start just keyless entry so not sure how playing with the other key would help but I’ll see if that works. Just need to remember where I kept the spare key.

Could I get rid of the message using ForScan?

I changed the actual car battery this weekend and the message went away for the key so that’s also an option, disconnect and re-connect the battery and it re-learns.
