Key fob battery low. But tests OK

Hello everyone, a message recently appeared on the car display, stating " KEY FOB BATTERY LOW" . The battery was tested for voltage and load current, and tested O.K., but to be safe a new battery was fitted, but the message on start up remains, anybody got ideas?, thanks.

Just changed a battery in one of mine without any problems. Try pressing the OK button when the "Battery low" display is up.

Just had the same warning. Changed yhe battery in the key fob and the warning went away. Easy to change, the fob splits in half if you use a knife. I happened to have a spare as my bathroom scales use the same battery.

Only a few pennies on line if you don't have one, though I wonder how much a dealership or Timpsons might charge.
