I had a mid 80s Cutlass Ciera that had a driver door that wouldn't open from the outside. Thankfully it was basically a bench front seat, so climbing though worked well enough. Later, I had a VW Jetta with a similar issue. Whenever it gold cold, the driver door would basically freeze shut. That was way harder for a big guy to climb into. I went through the back seat, and even the window, more than once.
Best of luck on the repairs.
