Locksmithing is a skilled trade that requires extensive training and a delicate touch, and there are many terms that locksmiths might use when they are on the job.
For example, the term ‘bumping’ means to open a lock with a bump key. A bump key is a general master key that can open a number of low-quality, cheap locks. Once these were available only to locksmiths, but with the advent of the Internet, bump keys can be purchased quite easily. Better locksmithing establishments will not sell these cheaper locks at all for this reason.
A sidewinder is a type of automotive key that has the teeth milled into the side of the key. The key itself looks like a solid blank, though it has the keys inscribed into the side. A dummy function is a piece of hardware that looks like a doorknob but which is essentially just a door pull. Below you can find some more locksmithing terms you may have never heard before.
