Is the tumbler portion of the lock completely removed? In other words, can you stick a finger inside?  If not, that should be your focus, get the tumbler completely out so you can see inside. Drill it out with a slightly bigger drill bit if necessary.  Be careful not to force a drill bit deep inside, you can drill through other stuff. Put a spacer or something to prevent it from slamming into the machine.
Once you get the tumbler portion of the lock out you can usually get a finger inside enough to push the door latch unit up and open open the door. The lock on most machines (I'm not completely familiar with your model) is a bar that goes from the bottom of the door to the top and drops onto latches in two or three places. That bar slides up and down when you turn the key....if the tumbler is removed you can replicate that action with your finger. You might need to use your little finger or borrow a smaller person.

In general, you will have difficult time taking the wood case apart, these machines are designed not to be easily penetrable. You might have to break glass. Having said that, I haven't run into a situation where I couldn't move the locking mechanism with my finger. I typically work on older machines though.

If someone is more familiar with your specific machine they will jump in and clarify more.

Last minute modification:  I re-read and saw you said the lock was set so you can turn with a screwdriver. Try lifting the door a little and turn the lock with a screwdriver, it might relieve some of the load. If the tumbler is drilled out and the lock turns with a screwdriver that should work.

Best of luck.

I just bought a slot machine without keys.  The previous owner drilled out the door lock and had it opened.  Unfortunately in transport the door closed and now will not reopen.  Do I just jam in a screwdriver and turn as instructed? I tried this but it didn’t seem to catch, not sure how hard to force it in, don’t want to do any further damage.  Maybe there is another way to get in (disassemble the wooden case?). Also, once open does anyone know where I can purchase a replacement lock and reset key? Any suggestions are appreciated!

Hi Bruce: 
Those are common monitors in the early games.
Sounds like you got caps which is really important.  Those are all getting to the point where Flybacks go out on them too, be sure to check the HOT and voltage regulators too.
Always discharge the 2nd anode cup on these too.
If you need specific parts reach out to Bob Roberts, they know that unit well and they usually have Flybacks in stock. www.therealbobroberts.net
Here is a link to a G05 repair video, I'm at my  9-5 job today so I didn't watch it in detail, but he talks through some of the component specifics and potential issues.

Please keep us updated.

Wow, thanks for sharing that, it sounds fantastic. I agree with Shortrackskater, I would love to see pictures of that recreation center and that game specifically. Thanks for sharing.
My machine still works, on it's own terms, meaning it takes about 20 minutes for the CPU to come to life. It plays great once it wakes up.
