Did you know that you could make duplicates of your keys so that you never get locked outside your house?
Yes, I know, making duplicates costs just a few dollars at the hardware store ... But you can make them yourself, just so you can be very proud and show everybody how you did it!
You will have to heat your key with the flame of a lighter until there are black char lines.
Then, press a scotch tape onto the charred part: the shape of your key will be apparent.
Press the pattern onto a tin can lid, plastic bottle or loyalty card that you don't use anymore.
With a pair of scissors, cutout the pattern very precisely.
I can see you’re doubting…
Now, duplicates all your keys and hide them in several places: you might need them in case of emergency.
