I have a 76 top on my 72. So your key doesn't work the lock on the driver door, did you try it in the passenger door. If the tab on the inside of the door by the handle doesn't lock/unlock the door then something is out of adjustment or broken, rusted. The mechanism isn't all that completed and I bet you can buy a new keyed lock assembly. Or if your key works on the passenger door, then you could rekey the driver door to match - not that hard if you have worked on locks before
If you plan on keeping the rig get a book(s). The factory ones are the best but a Chilton is better than nothing. Second go look at the pictures at the online places such as SOR.com.

added With the kick vents and not such a great fit on the door gasket anyone with a coat hanger can unlock a working unit in like 6 seconds - the clutch is your best anti-theft device along with a kill stitch and a fuel selector valve.
