In this Instructable, I tried to copy a key by taking a photo of it.
Before you say anything, I am aware that there are apps to scan keys and on-line services & kiosks where you can print them out.
Step 1: Take a Photo
I put the key on my gym's old membership card.
Reason for that - it's the same size as the credit card.
Then I took a few photos of the key.
Step 2: Edit the Photo
I found a credit card's template for the photoshop.
I cropped the photo and dragged it on top of the template.
Then, I copied the photo to a new a4 size document and made a few copies.
Now I had a perfect size key, ready to be printed on a label paper.
Step 3: Stick the Label on a Blank Key
I cut out the label and stuck it on a blank key.
Step 4: Paint the Exposed Metal
I used black nail polish to paint exposed parts of the key.
Before nail polish was completely dry, I removed the label.
Step 5: Grind the Marked Part of the Key
I put the key in a vice and used different files to grind the marked metal.
Key did not work with the first time. I had to make little adjustments. I made those adjustment without the vice, just by holding the key and grinding it with a file.
After a few tries, I was able to unlock the padlock with a key that was copied from a photo.
Never post a photo of your keys in social media sites.
