Key not detected when hot outside


New member
I have a 2013 MKZ & every time I go to my car after it's been in thesun, it says no key detected when I try starting it. It has no problem unlocking the doors or popping the trunk. I've changed the batteries in the fob recently too & no effect. It takes about 3-5 minutes of holding down the lock button to get the car to recognize the fob again. Any suggestions?
