My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. I wish he would have shown at least SOME of the filing. This doesn't really show how to make a bump key at all. Just what one looks likes.

  2. Dude, your fingers are gross.

    But awesome video, I never even thought about putting a rubber washer at the end of the key to speed up bumping and that is an insane speed that it allows for. Thanks for the videos.

  3. I have a high quality tool holder. half my drawers are locked. i dont have the original key but i just orderd a set of 5 bump keys wilk i be able to unlock this without my original key ?

  4. Is there such thing as a truly universal bump key that will work in most any brand of lock? What about bump keys for cars, is that possible?

  5. Oh my goodness, that "spring loading" the bump key is genius. I had to bump a lock I couldn't pick just last night and was even having a little bit of difficulty bumping it. I eventually got it, but it puts a bit of strain on the hands and fingers having to pull out the key every time. Thank you for this video.

  6. holy crap I just made a bump key. just bumped EVERY lock in my house. guess those are also being replaced. again…damn it bill, costing me money by teaching me yet another skill. thanks.wheres that video, bill. still waiting. snow aint that bad.

  7. Any idea if you could cut keys with a milling machine?
    Don't have a key cutter, but I do have a 3/4 size Bridgeport (actually a clone of a clausing) in the shop…. Thinking of rotating the head to a 45 degree angle so the corner of an endmill would cut the notch. Either that or get a replacement cutter for a key cutting machine and make an arbor for it….
    My thinking is that with setting up a way to hold the key in a repeatable position, I could figure out a chart that translates cut numbers into thousandths that I can dial in on the feed cranks. Have the key vertical, and then just start at the top, set the depth of cut, do the pass. Then raise the knee up to the next position, reset the depth, and make the cut.
    If I can figure it out and make it work, I might do a video on code cutting keys on a milling machine…

  8. Hey Bill, how can you tell which bump keys are for what?
    I have a set from Sparrows, but only the ones for weiser yale and schlage are marked. Its the 19 key set just having a hard time figuring out which ones are for which locks

    I have a bunch of different locks I got from a jobsite I was on after the demolish, they were being thrown out so just asked if I could have them to see how they are to pick and practice on.

  9. Thank you for taking the time for all your informative videos they are very helpful for a beginner like myself. The one question I have is at 3:10 of the video you show a key with 5 cuts and at 5:22 the bump key has 6 cuts does it make a difference? Again thanks for all your time.

  10. Thanks for the video, very informative. I have a question though. How do you define the pin positions? Is it something you can see by looking at the key?

    I've made 2 screenshots of your video (one with the original and one with the bump key), re-sized them to fit and put them on top of one another but I still can't figure out the logic. Here's what I've done: http://i.imgur.com/5Rl2VZ3.jpg
