Nissan Intelligent Key issue 4

My Nissan's intelligent key stopped working the other day, and it's been a real headache. The car won't recognize the fob half the time, so I'm stuck pressing the unlock button repeatedly or using the physical key to get in. I've changed the battery in the fob, but that didn't fix it, so it might be the car's receiver or a syncing issue. Anyone else have this problem?
