The definitive guide....
My background: I am an amateur DIY, but skilled and and have a engineering education. This job was very frustrating...but makes it that much more rewarding.
I want to thank Bushcal for his suggestion to cut out the latch, rather than drill. I am not sure if drilling is better but the striker survived and I had an excuse to buy a dremel. He also made it sound simple so it gave me the confidence to go forward. It took me 2 weekends (8 total hours plus time to order parts). I have updated his instructions below based on my experience because he is incorrect that the window track can be removed while the door is still stuck shut.
What you need: Tools (standard tools + Dremel, Lock assembly for Driver door 72150-S84-A02, AND a bushing 72134-SM1-003 (I think)) for a 1999 Honda LX 4 door
1) Take out car seat and make sure the window is all the way up.
2) After several attempts to pry out the door without the proper leverage, I removed the passenger door to see how it the panel is removed. I returned to the driver door and applied much more pressure and was able to get the panel off. The door panel sustained minor damage in the right hand corner as well as 3 of the clips. Although I was able to reuse the 3 damaged clips, I recommend you order these as well a head of time.
3) Remove the door control panel and interior door handle. Remove the door. Disconnect all electrical connections. Remove the plastic sheeting from the left half of the door. Carefully remove and save the linkage from the interior door handle.
4) Remove the black tube from the white latch protector. Remove the rods connected by the "swing" locking mechanism.
5) Remove the white latch protector. You will need a mirror to see the screw. Take note of the location of the white plastic latch protector (it took me a while to reinstall). Also, unlike Bushcal's instructions, you cannot remove the window track until the door is open. It is very difficult (but doable) to get the white latch protector out while the window track is still in place. If I had to do this again I might cut out the window track and buy a replacement.
6) Remove the actuator from the latch (3 tiny screws). I removed the 2 large screws connecting the actuator to the hidden metal protector and lost the screws and the orientation of protector (metal piece behind the actuator that took me a while to reinstall). You will want to note the orientation of the actuator protector (barely visible behind the actuator) and make sure you do not lose the 2 large screws in the door crevice.
7) Buy a dremel with at least 2 metal cutting disks. This is difficult (especially with the window track in place), but cut the lower part of the latch (right above the bottom screw) and cut the higher part of the latch (right below the 2 screws). I had to cut through the two rivets in between to pry out the metal chuck. Since the window track is still in place, it is very tight so I could only attack the top part of the latch when the cutting wheel had lost half its diameter. See pictures on next thread.
8) Next you will see some plastic behind the metal chunk you removed. I swiss cheesed it at a low RPM using a drill bit on dremel. Work out the plastic and you will see the latching mechanism. Play with it with a screwdriver while pushing out the door.
9) Yay!!! the door is open. Remove the latch and window track from the outside. Next steps sucks.
10) You will have one rod still connected to the door handle. Note how many screw turns are between the rod and the connector (mine had 4 AND the replacement mechanism will have a longer rod so I you will have to determine the number of turns on the new rod). Destroy the plastic housing between the rod and the handle mechanism using diagonal cutters (difficult). This is the bushing I refer to above as something you need to purchase. I lost patience and only partially damaged the bushing so I reused it when installing the new latch. I am not 100% sure the part number of the bushing listed above is the one needed for this step since I never ordered it.
11) Put everything back together and don't forget to check the mechanisms as you put it back together. I am slow so it took me 1.5 hours to put it all back together.
I was so happy I got this job done that I nearly locked the keys in the car testing the latch....so be careful checking the install
Good luck DIY'ers
