Although locksmiths are skilled in many aspects of their job, the making of keys is among the essential tasks. Keys are unique to each particular lock. If the key becomes damaged or lost, it is hard to find a replacement. A reputable locksmith is equipped with the right tools as well as the knowledge to make a new key regardless of whether the original key isn’t available. There are a range of techniques to create a new key. Impressing is one of them. It is an extremely difficult process that requires particular skills.

This is a skill that requires lots of work, but it’s essential for locksmiths to be able to understand. To learn more, continue watching the video!
