Where can I get a lock or latch for my door?

Dear Shaynak; the "key" to this dilemma is to get an friend to help you. For the hard ware that you need, you need to go to the nearest hard ware store, to you. A True Value or Home Depot, or what ever is popular in your neighborhood. Then select the proper door nob and then get your friend to help you install the device on your rented door. No lol here, honest
