Remove the door panel on the OPPOSITE side of the car. You can then see what door lock levers to "jimmy".

With the window DOWN on the offending side, you will have enough room to get a tool (coat hanger) down into the door lock mechanism.

The problem may be a worn door handle mechanism or a gunky lock.

Does the car have power locks? If it does, the actuator could be siezed, making it virtually impossible to open with the key.

Most tow truck operators, police/sheriffs carry a "slim Jim" drive to a local Starbucks.

Check out this thread... there are lots of excellent pictures...
http://forums.corvetteforum.com/c3-t...ock-101-a.html

Scroll down to DB's thread and he has an excellent picture of the door lock mechanism with the "key" lever you must push to release the door latch. Once you find the lever, you can reach down from the window opening with a long screwdriver and place the blade on the lever. Give the screwdriver handle a sharp blow and the latch will release. You can do this with nothing more than having the window down all the way.

Here's the picture... copy it to your files or print it out... if you own these cars long enough, you're gonna need it...

Good luck... GUSTO

First thing to check is make sure the outside door handle is all the way up. If its sagging, the lock mechanism won't unlock, or if the linkage to the outside door handle is out of adjustment, same issue.

Thanks Gusto I'll pass this on... Two issue though, the linky does not work, and the other issue is, (well for me anyway) is, that my 72 has a plastic guard over the mechanism Muddy

Muddy,
Yes there is a plastic cover that sits on top of the lock mechanism. It is a very lightweight plastic cover that keeps water from running directly over the lock that finds it's way inside the door. You should be able to move it aside without damaging it and get to the lever on the lock that needs to be depressed.

Funny the link and picture worked last night when I posted it. I do have the picture on my hard drive at home and can email it to you if you'd like. Just send me an email address if you want it and I'll shoot it off to you.

It's one of those tasks that if you've done it a few times, you have no trouble locating the lever and opening the door. It has been a lifesaver for more than a few friends over the years.

Good luck... GUSTO

I had this happen with my 69 years ago before I removed the levers and latch assembly to clean and adjust.
I was able to work the lock **** and inside handle until it released. Try to unlock the **** while ratching the inside lever. If this work pop the panel and look closer. I had the 90* rod ends bent on one and the latch gummed up. Remove the latch, clean with brake cleaner and dry lube it. Then setup and adjust the rods.
About as much fun as grouting Mexican tile.

I noticed that the picture is once again linked above. If you place the tip of a long handled screwdriver on the lever (arrow is pointing to) it will release the latch.

I agree with what others have said, if you remove the latch mechanism and clean it good with a strong solvent it should remove all of the old grease. Once you get it thoroughly clean re-lubricate it with lubriplate (some call it white grease) it should be good for another 10-20 years.

It's been my experience that these things tend to get gummed up from old grease well before the fail from wear.

Good luck... GUSTO
