Security deposits are meant for damage and excessive dirtiness upon move out. You should not hold any of the deposit for anything that is considered "normal wear and tear."
It sounds like they kept the house in great condition, and if it does not exceed the "normal wear and tear" guidelines, and do not owe anything additional such as late fees, utilities, etc. you should think about returning the full amount.
I think it should be the landlord's responsibility for changing the locks and those are some of the costs that are expected for a landlord to pay.
