Key Cutting

Key cutting is a process that serves a plethora of purposes, which is one of the reasons why the skills of a good locksmith are so important to society. If you�ve never required key cutting services before, it�s fairly safe to say that you eventually will in the future. Do you keep a set of keys to your car, room, home, office and locker? If you do, then you�ll know how important it is to keep spares in case you lose the keys you have with you. But how exactly do locksmiths go about the process of cutting keys? Is the practice all that difficult?

Defining Key Cutting

In metalworking circles, key cutting is the process of shaping material (usually a type of metal) to a specific shape and size through the removal of excess metal. Key cutting is the primary method of duplicating keys; it is also the fastest and cheapest method. A locksmith typically requires the original key to make a copy made out of. The process is fairly simple and quick, and is offered in nearly all hardware stores around the world.

The Key Cutting Process

A key cutting machine is almost always involved in the key cutting process�the type of machine used will depend on your locksmith, as well as the complexity of the key that requires duplication. Two keys are needed to begin the process--the first the original key, the second the �blank� key. A blank, as the name suggests, has no dents and grooves which are needed to mate with the pins inside a lock. Both keys are inserted into the machine, with the original literally acting as a guide in guiding the mechanism that cuts into the blank key. The cutting instrument is usually a large wheel with a sharp edge, which removes the excess metal from the blank�s edges. More sophisticated machines will use laser technology for even more accurate results.

Once the cutting is done, the locksmith will then take the two identical keys, and begin process of deburring the new duplicate. This involves taking metal scrub or steel wool to remove small metal filings that may still be on the new key. This process is particularly important, as sharp filings can leave nasty lacerations on the skin. Furthermore, excess filings can also affect the shape of the key, and can even destroy the pins inside the lock, making it permanently unusable.
