For some doors, you might not want regular locks. For those areas, perhaps this Gatehouse swivel hasp lock with screws, this First Watch barrel bolt lock or this Stanley brass hasp lock with hook, (all available at Lowes) would be appropriate.
Over at Lowes you can find a range of different door hardware products including different types of locks. These types of hasp locks with barrel bolts are perfect for some storage units, pantries and other spaces where you need something very rudimentary and simple. These different products differ quite a bit in construction and design. You can find a range of Gatehouse, Stanley as well as First Watch hasp locks in finishes such as brass, nickel and oil rubbed bronze. Most of these products come complete with screws and such necessary accessories, so for most of the time you don't need anything else.
Fixing up your home and making sure all door locks and hinges work is pretty easy to do. The aggravation that poorly functioning locks can cause is bad enough, therefore, it's well worth it to replace old units when they are past their prime, and thankfully there are lots of options to choose between at Lowes.
