Cutting keys that are out of the ordinary…
Operating a small locksmith shop in Brisbane, Australia is never dull. Often we get calls to cut some pretty strange keys. Well I shouldnt say strange, just out of the ordinary.
Carpenters Rim Locks are one we dont see too often now days. They are the ones with that look like an old jailers key. The locks are a solid rectangular shape and are screwed to the inside of the door with the keyhole going right though. These keys are made from cast iron or brass. They have to be cut by hand and can take some time to do properly. We use specially cut down files to get into the intricate corners. 1 key can take a couple of hours to create.
Newer keys are sometimes cut using a CNC milling machine. We have specially adapted software to cut keys of different types. A new key we have never seen can be programmed in to the milling machine computer to be able to cut a key quickly and accurately. See an Audi key being cut here. Most keys can be cut using the same method. A Rotary table is used to cut keys that require angle cuts. This is only really useful for keys that are not able to be cut on other machinery. Companies such as Silca make great key cutting machines for a wide range of keys.
