So my car won’t respond to either of my key fobs. The red light blinks but nothing happens and I can’t get into my car. I’ve read about the key On the bottom, but I have buttons on my doors and not keyholes. It’s a 2018 TLX A-Spec. I need urgent help on how to get into my car and try to start it

 

Your driver door still has the keyhole

 

^ what he said.
Your key fob batteries are probably dead. They only last about one year.
Remove the physical key from the bottom of one of the key fobs and open the door.
To start the car with a dead key fob battery, you need to push the start button with one of the key fobs. The car will trigger the proximity chip embedded within the fob and recognize it, and start the engine.
