The Mechanics of Key Copy

At Aventura Locksmith we perform at least one key copy every day. Most people will come and go without even thinking twice about the process. However, for the inquisitive few we’ve decided to inform you on the intricacies of the key copy!

The Mechanics of Key Copy

First, to talk about key copy we need to explain what happens. There are two keys; we align them on a ‘tray’, and then we move that tray along a groove, and a blade replicates the grooves of the first key. In a nutshell, that is the entire process from beginning to end.

But the details are what is most important here. The amount of precision is easy to learn and difficult to master. Firstly, the two keys are set into place by dual vice grips. To properly align them, the locksmith must be diligent in ensuring that they are exactly to the line to the centimeter. In fact, over 50% of the time the locksmith is preparing duplication, it is to make sure the alignment is perfect.

After the keys have been set into alignment, the locksmith will find the best angle to start from (often back to front as to match the grooves. Similar to the equally distance vice grips are a guide and a ‘spinning blade.’ This spinning blade is connected to the motor in the rear and will slice through the key. The blade and the guide are in perfect alignment so wherever the guide touches is where the blade will touch exactly. So when you have a guide touching a specific point of depth on the original key, the spinning blade will cut into that exact point on the blank key. After you’ve pushed the track through the motor once, you will have another key with the exact cuts and grooves like the original key!
