So I am going to cover the basics of how to make a bump key how to make and use a bump key to quickly unlock most residential grade locks and if you still don't understand, I am going to put a video from infinity exists down below and a place were you can buy a set of bump keys if you don't have the time to make them.
Step 1. Is to find a key that you do not use anymore you will be unable to use it for its original door unless you are bumping it with the bump key.
Step 2. The other main materials you need are a file to grind down the valleys of the keys and just to clarify the valleys are the part between every tooth on a key or as shown in the diagram of the key in the low part of the pattern cut you want to grind that part down to the shoulder. The shoulder is the line at the middle of the keys body.
Step 3. After you have all of that it will take about fifteen minutes you could do this with a drill like in the video but it is very dangerous because it could completely mess up the bump key if you don't have a steady hand.
