Lock Picking Tools From Scratch




Introduction: Lock Picking Tools From Scratch

About: Maker. Love to create.

Hello friends! today I'm going to teach them how to make tools to open any padlock or drum lock with only a Wiper/Washer!

For this project we will only need:

  • Wiper/Washer
  • Some tools like a grinder or bench grinder
  • files
  • blade of Jigsaw (optional)
  • pliers

Let's begin!

Step 1: Removing the Wiper/washer Blade Insert

The first thing to do is to disassemble the wiper/washer, for that we must remove the rubber weatherstrip, and then remove the two metal blade insert.

Step 2: Prepare the Blade´s

Now we take one of the rods and proceed to mark and cut, we need to make two cuts, one of 4 inches and another of 3.5 inches.

Step 3: The Torsion Wrench

Now take the 3.5 inches and bend the tip to 0.3 inches (1 cm) and then apply a twist to the middle of the tensioner to give it more rigidity.
We already have our tensor ready! we only have to make our picks


Step 4: The Picks!

To make the picks we occupy the blade of 4 inches (10 cm), with a round file we roughly chopped close to the tip and once made said muezca, with a flat file we match the surface about 1.5 inches (4 cm) as we can appreciate in the pictures...
Instead of wiper blade, we can use the blade of a jigsaw tool.

And ready! now we can open any kind of padlocks or drum locks!

Step 5: Final & Templates

Here I leave this template so you can take as an example when making your picks! In the video you can also see how a ganzua works with a blade of jigsaw tool. I hope it has been useful, see you in the next instructable!

Thank you for your vote!

    Thank you for the schematics. I am needing to make a couple of sets of lockpicks (they don't need to actually work, just look the part) as late birthday presents, one set to be human sized and the other miniature sized suitable to be used by a cat (don't ask). They just need to look good and with this instructable I reckon I can make them to look realistic. Thanks again, I know we've got a couple of old wiper blades around so you've solved a major problem for me. Now for the rest of the 'tool kit' I have to make. Great instructable.

    Actually, those thin strips of steel you see often are from street sweepers! They are also a good material for making picks- they're made out of high tensile steel, meaning they spring back to their shape after flexing.

    Their suitability for picks and rakes was going to be my next question! Thank you for anticipating it :-)

    Yes, I'm thinking the sweeper bristles are thinner on both dimensions than a wiper blade, & might be easier to fab pick\rakes from since you won't have to remove as much material from to get into a smaller space. But I do appreciate the author's idea, because I'm thinking the stiffer steel in a wiper blade will be much more appropriate for the tension bar.

    I see that many here mention the sweepers of bristles, but I do not know what that is about since in my country the streets are not cleaned with sweepers, so try to use a material that is within reach of everyone.

    Ah, understandable. But so am I friend. I find sweeper blades in Michigan, USA; easily found in parking lots & gutters by keeping my eyes down. But if your country doesn't have street sweeps, I can see how finding good steel from worn wipers could be used as well, & so you did. I'm really into getting parts from my local auto scrap yard, the seat belts by themselves are so useful for strongly repairing or replacing straps on backpacks, purses, etcetera.

    I like the Idea of using windsheild washer metal strips. Probably what you see on the streets are from Street sweepers. The brushes are made of spring steel and are good for use in making Lock picks too.

    Vwery good Instructible

    I made mine from used Coping saw blades and they have never failed me in 30 years,nice instructable!

    Now I know what to do with those wiper blade steel ribs! Added life to my dead windshield wipers!

    just as with dental picks, these can be useful for several reasons not related to lock opening. Just saying. Nice instructable._ga-

    So obviously ordinary cylinder locks offer no real protection. What are the best locks to use?

    I like the way the military rates locks and safes - hours.

    We had a 2 hour door lock and a 4 hour safe for storing classified records in. That meant that you had to have a response in <6 hours if the main alarm went off, and <4 hours if the secure area alarm went off (and if the secure area alarm went off in <2 hours after the main entrance... well, that would be a great-big-investigation). Nothing was "protected" or "secured"; it was all in "time to get in."

    Locks help keep honest people honest. Doors and windows are not truly barriers. Even walls can be penetrated with enough force or the right tools. While there are more secure locks than the typical pin-tumbler locks, they are considerably more expensive, and nobody wants to live in a bank vault. Picking locks takes time and practice - and a little bit of luck even for a professional. They slow down entry and make a thief "prefer to go elsewhere", just like alarms do.

    Well buddy, no one here is talking about stealing ... but these tools can be very useful if you ever lose the key to your bike's padlock for example.

    Well I'm not sure, in my country the locks are different, basically this method is very useful to open padlocks

    Not only is this really cool, it also explains where those thin strips of steel I see lying on the road came from! Thank you :-)

    Those strips of steel have broken off from the street sweeper/cleaner brush.

    Ah! Of course. I see a couple every time I'm on the bicycle and there can't be that many disintegrated wiper blades. Thank you :-)
