So the battery in my Lexus died sometime while I was out of town. Come to find out the key wouldn't go in the lock either. I used some WD-40 and managed to get it in all the way but it won't turn.

I picked up some unfreeze lock stuff from the hardware store and tried that but it still doesn't open.

The odd thing is, if I use too much force, the whole lock ends up spinning around (perhaps this is a safety measure to prevent keys from breaking?). Does anyone have any suggestions of things to try? Or ways to pop the hood from the outside?

If you have used remote locking for a long time, your key will have worn down from being used in the ignition but the door lock will be almost new and probably a bit seized from lack of use.

WD40 will help. Just keep soaking it and wriggle the key gently. Gently twist it back and forth. It might free up.

Do you have another key? It may work better if it is less worn.

Or have a look at your key. Does it have a code stamped on it? If so, take it to locksmith and get a new key cut from the code (rather than copy a worn key) then try that.

Worst case get a locksmith to break in for you. If you want new keys cut, the factory code is stamped on the lock barrel in the drivers door. I had this done for under $100.

If your main battery is flat, you may be able to pop the bonnet, or put a jumper lead onto a positive wire from under the car, such as onto the starter engine lead. It might provide enough power to unlock it.
