Smart Key Battery QUestion

[ASB]

Re: 13 plate XF Sportbrake, 35000 mls

The warning message Smart key Battery Low came on.

The old battery was 2.5 v I replaced the battery in the key, the key works and has a good range but the warning message stayed on.

I checked with the second key and the warning message is still there. That key also works at a good range.

I can't see any means of resetting the warning system, is that necessary?. Any thoughts / suggestions  to clear the message would be very welcome please.

Try removing 12v car battery leads and put back on.  Probably will reset the computer!
