My Explorer is having weird issues with my key fob. Vehicle is push-to-start, and also senses when you approach and will unlock when you touch the handle. All of that works fine. What is becoming more and more sporadic are the lock/unlock buttons on the fob. Like a third of the time, they don’t work. But I’ll have the key on me, and the approach detection always works and the vehicle always detects the key to start. It’s not a low battery issue, as the vehicle will sense that and tell you on the screen (had that happen before). Any ideas?
