Replaced the door latch in my wife's Honda. Door would not open; this was a fun job getting the door panel off without damage while the door was shut, but with my youngest son's help, we got it done. No drilling/cutting necessary. Found the right pin to actuate on the old latch to get it to release and get the door open, then replaced the latch. All is well now.
Would have run around $800 at the dealership, and they would probably have drilled it out.
