For the model 3 and Y with the mechanical handles you press on one end to get the other to pop out

If it’s iced over, you can press on the other end and there’s a little room to effectively rock it back and forth a bit to break the ice. I live in Massachusetts, I park outside, and this is my third winter with the car, and I’ve only had to do this twice. It worked each time with minimal effort

I have no idea what the model s and x do with the electronic self-presenting handles. They ought to have a defroster or some sort of vibrator to do similar. Not that it would help in an accident
