Is this weather proof for rainy and extreme hot temperatures? Using on a main gate.

This should be fine. It’s all mechanical, no electronics.

Can codes be deleted/ erased to start new ones?

Scott - this is a mechanical system with no electronics. You set the numerical code by inserting "blank" spacers where you don't want to include a number in the code...and easy and foolproof process. We use a similar mechanism for our controlled substance lock box. By the way - a solid lock that is truly unaffected by water (even from a high pressure washer) unlike every electronic entry lock I've owned which I had to tape over before pressure washing or buy a new one after.

If I enter the wrong code, how do you "unpunch" the number or numbers you pushed by accident? Do you push them again to "undo" the push?

If you punch in the wrong code the door won’t open, simply start over and there door should open the next time
