My lock works backwards. Hit the lock and it unlocks, punch the code and it locks

I'm assuming you are dealing with the Powerbolt, since you didn't mention the model of lock you have. This problem is probably because the "handedness" of the door is set opposite of your installation. That is, you may have what is called a "right-hand door" and the lock is set for a left-hand door, or vice versa. In other words, what side the door hinges are on and which way it therefore swings open.The Kwikset lock has an internal jumper which needs to be moved to another position to change the function.

11. Door handing: I have installed your Powerbolt, but when I push the Lock Button, it unlocks? What should I do?
First remove the cover on the inside of the Powerbolt unit. On the right hand side under the batteries, you will notice that is says "Door Direction Jumper". If the cap is mounted on Prongs 1 & 2, carefully remove it and move it over so that it mounts Prongs 2 & 3. A is right handed, B is left handed.

This link will illustrate how to remove the cover to change the jumper:
