2015 CX5 locking system faulty

Greetings. My walk away locking is functioning properly but when I return to my vehicle and press the door handle button it locks again sounding one beep. Normally for the past 5 years or so it would unlock after pressing the door handle button giving two beeps. Anyone have a fix? I changed the fob battery and reset to the factory setting, still not working properly.
