Introduction: Open Any Padlock

Picture of Open Any Padlock

This is not my idea, its been floating around the internet for a while. Its a simple and cheap way to make a padlock shim out of a can of soda or any thin metal.

Step 1: Parts

Picture of Parts

The only real parts you need for this are a can and a pair of scissors or a razor. If for some reason you dont have a can you can use any metal of the same thickness or slightly thicker.

Step 2: Prepare the Metal

Using the scissors, cut off the top and bottom of the can. Then make one long cut down the side of the can to get a sheet of metal. Then flatten out the sheet, and cut off the jagged sides of it, so you end up with a smooth rectangular sheet of metal.

Step 3: Make the Marks and Cut

The instructions I read for this say to use a strip 1" x 3", however I found it easier to use a slightly more squarish piece works better, so use something about 1 1/4" x 2 1/2". Mark out the rectangles onto the sheet of metal using a sharpie, and then cut them out.

On the smaller rectangles, mark off fourths both vertically and horozintally.

Step 4: Mark the M

Picture of Mark the M

Draw a M shape on the rectangle. The M should start out 1/4 in from the left, and shoud be 1/2 up from the bottom, it should curve down so the bottom part is 1/2 in from the left, it should be mirrored on the other side. Its kinda confusing so just look at the photos. After you draw it, cut it out.

Step 5: Folding and Shaping

Fold the top 1/4th down, then fold the 2 side parts up and over. After you finish folding wrap it around a bic pen or some round object, roughly the same diameter as the bar on the padlock.

Step 6: Using

Picture of Using

The best method to open it is to have the part of the shim that will go inside the lock on the outside of the bar. Push it down into the padlock, and then twist to unlock it. It can be very hard to master, dont give up. It will probably take a few minutes to get it to work. These are only good for a few uses, because they begin to crumple up and will no longer fit in the lock. A good practice technique is to use an open lock, look inside at the part you are trying to force open, and try moving it while the lock is open to see what you need to do when it is closed.

A flat blade screwdriver and 1 tap with a hammer is all i ever used, and neithr one ever wore out and got crumbly.
you seem to want to be STEALTHY--are yo up to No Good ???

I think it's just better form and more respectful of the art of lockpicking to leave the lock unharmed in the process of opening it.

speaking of burglary tools. when I was younger I used a hammer and screwdriver and screw to break into drink machines...not smart and only did once but I got caught. I was charged with a class 5 felony because I had used burglary tools. I ended up pleading down to petty larceny so I didn't have a felony. moral of can always be worse than you think so if you aren't breaking into your own locked thing don't make the tool. some people like me learn but others dont

Aluminum is too weak. I created this set in 1985 from a brass alloy which acts as a lubricant and is verry strong. The more you use them, the smoother they get. See my webpage concerning brass..

Unable to get the info you promise on your blog, a bit sad I am
