How much do you know about your keys? Would you be able to tell if they were a fake? Read on to learn more about your keys, and what the key numbers stamped on them mean for each type of key.
Is Your Key A Convincing Copy?
Making a copy of a key is nothing out of the ordinary. If you’re about to go out of town to visit relatives and you need someone to come and watch your pets, chances are they will need a copy of a key made for them. This way, they can go in and lock up again on their way out. Using a micrometer, you can take a close look at how the cuts on a copy compare to the cuts on an original key. The margin of difference is almost undetectable at .003 inches. If the key is an imitation, then chances are it, and its associated key numbers will only be useful to whoever made the key in the first place.
The Model Numbers
Model numbers are another form of key numbers. You’ll find these on key blanks. The key blank is what you need to make a duplicate key. Although you might think they key blanks are interchangeable, the model numbers and by extension, key numbers on these keys help make them unique. The keyways and blade lengths of the blank must be the same as the original for the duplication process to work correctly.
Master keys have a special system for arranging the key numbers. The master key itself has a certain key number associated with it, “A”; and since sub-master keys exist, these would be given a key number “AA” or “AB,” for example. Passkeys are slightly different since they depend on whether they belong to a master key system or a sub-master system. In these cases, the numbering would be something along the lines of “1AA” for masters or “2AB” for sub-masters.
Key codes are key numbers assigned to keys that open something that isn’t a door. However, doors can still have codes, just through integrated access control systems with keypads and not necessarily actual physical keys. These keys can be used to unlock filing cabinets, bike locks, and padlocks that aren’t found on a regular door. If you lose the key itself but hang onto the key code registered to it, you would be able to get a replacement key cut easily enough.
