I had to search for this because it was time to assemble my glove compartment lock and I couldn't get my lock apart. After fighting it for about 45 mins, I decided to look for my post. After reading my own instructions, I see that I forgot to take the key out. Luckily, I had "TAKE THE KEY OUT" in my post above. I edited it to say it more than once now so you can't say that you didn't see it. I also added that using the key during reassembly lets you slide it right into the latch.
Maybe we can make this a sticky?
