The Copy of a Copy Effect: Why Key Copies Sometimes Fail

https://mrlocksmith.com/

Key Duplication Experiment: How Many Copies Until Failure?
In this episode, we explore the effectiveness of key duplication by repeatedly copying a key and testing each version. Starting from the original key, we create subsequent copies and observe their functionality. The first copy works perfectly, but as we reach the seventh and eighth copies, the keys increasingly struggle to turn, with the eighth copy ultimately failing to work.

Why do keys become unreliable after multiple copies?

Each time a key is copied, minor inaccuracies and imperfections are transferred to the new key. Over successive generations of copying, these small errors accumulate and can lead to a key that no longer fits or turns smoothly in the lock.

How many times can you copy a key before it stops working?

The answer varies depending on the quality of the original key, the accuracy of the key-cutting machine, and the material of the key blank. In our experiment, a high-quality machine allowed us to make up to eight copies before the key stopped working. Most standard machines, however, might only support four or five generations before problems arise.

Can a poorly made original key affect the quality of the copies?

Absolutely. If the original key has any imperfections, those will be magnified with each subsequent copy. Starting with a well-made original key is crucial to ensuring the best possible duplicates.

What should I do if my copied key doesn’t work?

If a copied key doesn’t work, it’s best to have it checked by a professional locksmith. They can determine if the issue is due to wear on the cutting machine, a problem with the key blank, or if it’s simply a matter of making too many generations of copies.
