We all know that person that is always losing his or her keys. The lost item could be anywhere in the house, car, at work, or worse, somewhere out in public. Sometimes, it’s not even worth looking for them; it’s better to wait for them to reappear. In the meantime, the best option is always to have a back-up set.

For his latest tutorial, YouTube guru, Dave Hax, has come up with an easy hack to make your own spare key at home. All you need is a lighter, some tape, and a lid from a can. The trained engineer loves finding shortcuts that make life a little bit easier.

The new key will not be as strong as the original but it will serve its purpose until the original is found. Anytime you are working with sharp materials, it is recommended you use gloves or pliers.
