My grandma lost her pair of keys to the front door of the house so she gave me $20 to use my pair to go to Home Depot and have them replicated. How much exactly is the cost of the whole ordeal and how long will it take? To Chris - Don't be offended by the wording. It's just the way I type. Anyways if you really want to know indepth, my mom is trying to kick her out because my grandma had a tendancy to beat her and lie to her as a kid. I'm just being nice by making her keys again and I just wanted to know the price because I thought it was going to cost like $10 each or something. Don't go saying I'm immature since my mom told me not to go make her the keys.
