Hey, can I return an opened door look with some damages on the actual lock this evening? In exchange for the correct lock of a different brand?

Call the store... we are only other shoppers and have no jurisdiction on their return procedure

I would ask them. At the very least you should get store credit.

If it doesn't have too much damage, you'll be able to return it, just don't tell them about the damages

I would say yes they seem to be very good with returns and it never hurts to try. Good luck
