You can adjust- one of the lower points that the window mech attaches on the bottom of the door, accessed by a plastic grommet on the base of the door- pop it off, loosen the 10mm bolt which allows for a few mm movement to make the window sit closer or further away from the seal
The door lock isn’t like the old (as you describe) tuning fork mechs- from memory
Take the plastic grommet off the door that sits near the door latch
Insert a hook to slide the metal slider which allows the door handle to Unclip and move up/away
Go back in the same way you unhooked and unscrew the Allen bolt which holds the lock in place
Put the key in the lock and quarter turn it to allow it to be slid out
