How detailed does it have to be?

Are you showing it opened or closed?

See my next post for a quick run down of what it takes to create a simple padlock.  There is one other option and that is to find one (in 3D) that someone else already created and use that instead.  But that would be cheating now wouldn't it?  And you really do want to impress people with your 3D skills so you better do it yourself.

Do you have any experience working in 3D?

Here you go.  A very basic (small) padlock.  Create the body and extrude it (or use PressPull) to give it height.  Create a centerline path for the shank and extrude or sweep a circle.  That's it.  Finished.  Go for a beer.

My new and improved version.
The shank has been notched which you can plainly see.  What you can't see is the "catch" inside the hole where the shank goes when it is depressed and on the bottom I added the hole for the key.  The body of the padlock is on one layer and the shank on another.

Last image.  A little branding for my new "LOCX" padlock.  The name is cut into the body of the lock.  Had to get a bit creative to achieve the final result.  Probably a cinch to do in Inventor.  AutoCAD...not as easy.

Hello John!
 
My son has to do a project for class where he has to show a padlock.
the padlock measures are enclosed.
If it is possible to do it step by step so he can learn I will appreciate it.
Or if you can send it as a file.
thanks
Luis

I might be able to help if I could read those dimensions but the image is so small I'm having trouble doing so.

Anyway, the process is basically as I have shown in the first image I posted. 

In plan view create the profile of the body.  Switch to a SE isometric view and give the profile height using either the Extrude or PressPull command.

Create the centerline for the shank using the line and circle command.  Trim where necessary.  Use the PEdit command to join the two short line segments to the arc (one half of the original circle).  Draw a circle equal to the diameter of your shank.  Use the Sweep or Extrude command to extrude the circle along a path as defined by your centerline.

Make any further additions as required.

Of course your son will have to know how to manipulate his view(s) and how to reorient his UCS.  I suggest he turn on the UCSICON as a visual reminder or utilize the ViewCube.

This is a rough approximation since I could not read the dimensions off your image.

Start with a 2D drawing.  Set up 3 layers as follows:

Body, Color: cyan
Shank, Color: red
Centerline, Color: yellow
