The fob had worked for me for two weeks until today. I had used proximity lock/unlock, started car, etc until today. Did get the “not detected” warning every time I got in car but it went away and I drove using fob.
Today I have the won’t start car and won’t unlock car using proximity issue. Buttons don’t work. But, I can approach car and push handle in and it presents. I then use the key card to put it in gear.
I should add, fob buttons work now - I’ve disabled proximity lock/unlock, so the fob now works when I press the buttons to luck and unlock. Still need card to start. But, I can not push the handle to lock. I can push handle to unlock, but am just using fob buttons for now. So a “modified
@DrZorro method”.
Tried new battery - no change. Definitely not just a battery thing.
Wonky day but key card is working, so I will use that, as others have.
Love the car, not piling on, just sharing my experience. FWIW I had same issues with my 2016 X, but they were solved.
