So I'm in the process of reinstalling my locking glove box after disassembling it a long time ago. I got the lock and latch reinstalled on the box using the correct key for the lock. However, now the latch is locked in the closed position, and the knob is locked and the key won't turn it. It is essentially now acting like I am using the wrong key, but that is not possible. I have looked up videos on removing the lock/tumbler, all I can find is stuff on non-locking boxes. And you need to use your key on locking ones, which clearly isn't working now for some reason. So, does anyone have any ideas here on how I can now get this open? Here's what I'm looking at.

Square body trucks never came with a locking glove box. Some 1980's models might have a locking console only.

You can mix and match parts form other GM models for the parts to have a locking glove box. If the mounting nut is too long, it can jam up the lock. An example is using a console lock and nut on the glove box.The nut is too long.

I've owned this truck since 1992, I'm the second owner, and I still know the original owner. 1981 Custom Deluxe (now it's all custom redone). This locking box is definitely original, uses the same key as the doors, at least it did til I reassembled it yesterday. I noticed today that the one original key I have has a bend to it, so maybe that's why it won't unlock now. I'll be taking it to an old school locksmith in a couple days if no one has an idea how to remove it while locked.

"custom redone" Re-keying a lock isn't that hard to do.
If the key will not turn the tumbler, then drilling the center is one of your removal choices. Another choice would be to break the latch off. As in most automotive locks, you need to turn the key tumbler to the open long slot. Pushing the release allows it to turn further to that open slot.

I agree.

Especially on a Custom Deluxe trim level.

Get a lock pick set. I picked one up and with a little practice was able to open a locking gas cap for a project I was working on. It also came in handy when I threw out some "extra" keys that weren't as "extra" as I had thought.

I just confirmed with the original owner that it was there when he bought the truck new. So I guess I have a one of one numbers matching Custom Deluxe locking glove box, Bring A Trailer here I come. :shrug:

I didn't buy either new, but my '89 Jimmy(K5) and '90 CC both had glove box locks when I bought them. I would find it odd that both had been modified in that way and that so many I have come across have locks.

I believe the glove box light option came a long in the late 80's. Possibly there was some glove box convenience package that included both???

Did you take your truck to bring a trailer or did you try the second key that isn't bent?

You may be right about the later model squares. The utility company I worked for stop buying GM trucks in the 1980's. Lord knows I give thanks for Fords. Always something to fix.

Only have that one door/glovebox key. I realized the more I mess with this lock, the higher the chance I scratch my perty black freshly painted glove box door. So locksmith it is on Thursday. And I'll get some fresh keys while I'm there.

memories can be blurry especially with how thick rose colored glasses get. Not saying hes lying but that the lock being there now, and him owning the truck since new, its far easier for his memory to be persuaded it was always there rather than in 1983 someone stole things out of the cab and so he wanted a place to keep things just another level of secure so had it put in, but never had issues ever again. So because it was rather minimal one time experience, his brain shed that information as unimportant or at least lower importance and pruned it as a healthy brain is supposed to.

But im also not going to say with confidence they didnt come locking or that they couldnt easily be had with a locking glovebox. crazier things have happened, like dealers removing badging to install gimmicky ones.
