I just learned that the key Fob has a power saving mode. It’s in the OM, but somehow I missed it and recently my car has been saying ‘key fob not detected’ every time I go to start it.

You’ll know if your fob is in this mode if the little red operation light doesn’t flash when you press buttons on the fob.

If this happens to you, press the lock button on the fob 4 times in 3 seconds and this will activate the red operation light. Then hold the lock button for 1.5 seconds and the fob should go back to ‘normal mode.’ According to the manual, this procedure works the same to put the fob into, or out of power savings mode.
