Glove Box Lock Removal

Hey guys. I've seen postings all around the internet for taking these latches off if they're the non-key type. I've seen a few postings for the keyed locking latches and it appears as though you need the key in that case to remove the latch.

What do you do if you have a locking latch and you don't have the key? How do you remove the latch. My son and I have fooled with this latch several times over the years and we can't access the tab to push in. It sounds like the latch has to be in the "locked" position to do that. We can find the hole to push into but it's very solid in there with no tab showing.

I'd prefer to not have to risk damage to the door with a die grinder or other tool to cut it off. Thanks!
