1971ray

I have a 1971 Stingray with no round key, only the square one. Square on won't open the lock to access the spare tire.

What options do I have?

wheel grinder cut off saw should work fine.

You might be able to unbolt the lock hanger from under the rear.
You can see from this diagram where the two bolts are located.

remove the bracket/bolt by removing bolts number 16 using the pictures from DonnieP73's response above and then go to the link below and look at the pictures/description to remove the lock.
works quite well.

Is the glove box locked? If not you could take the lock out and have a locksmith determine the lock number and make a key. If the glove box lock and the spare lock are original, you have a key that works without a big hassle.
If the glove box is locked, it still may be easier to get the lock out. It seems to me that is the easiest way to go. Worth a try.

I just picked my spare tire lock using the info in the link posted above. I didn't even bother to try and unbolt the hanger first. Just layed on my back and started messing around, it took about 15 minutes. I bought a set of four different dental picks off ebay for $5. Now I know exactly what I'm doing I could repeat the process in 2 minutes. FWIW- I had better luck with an L shaped dental pick instead of the round hook noted in the link.

I have the round key and and it still took a can of WD-40 and an hour of screwing around. I just leave the lock off now. The lock is just there to protect the bolt head. If I can't get to the bolt head when I have a flat - I may as well not carry that heavy spare tire.

there is a rubber cover that goes over the spare tire lock to help keep the weather out of the lock, may not be 100% but it helps.
