You have a copy made of a key, you get home, and it will not turn, or it sticks, jiggles, and only works if you fight with it. It is a surprisingly common frustration, and it usually comes down to one thing: the quality of the key cutting. A key is a precision object, and small errors in how it is cut make the difference between a key that turns smoothly and one that barely works. At Super G&R Locksmith, here is the truth about why key cutting quality matters so much.
A Key Is More Precise Than It Looks
That little piece of metal is actually a precisely machined tool. The cuts along it correspond exactly to the pins inside your lock, and each cut has to be the right depth and in the right position for the pins to line up and let the lock turn. Even a small error, a cut slightly too shallow, too deep, or off position, means the pins do not align properly and the key struggles or fails. This is why professional key cutting in Calgary is about accuracy, not just shape.
Why Cheap Copies Often Fail
Not all key cutting is equal, and this is where many bad copies come from.
| Factor | Effect on the key |
|---|---|
| Worn cutting equipment | Inaccurate, sloppy cuts |
| Copying a copy | Errors compound with each generation |
| Poor-quality blanks | Weak or ill-fitting keys |
| Rushed or careless cutting | Wrong depths and spacing |
A key kiosk with poorly maintained equipment produces imprecise cuts. Worse is copying from a key that is itself already a copy, because each generation of copying adds a little more error until eventually a key simply will not work. Cutting from an accurate original, on well-maintained equipment, with quality blanks, is what produces a key that turns properly.
Copy From the Original When You Can
One of the best pieces of advice we can give is to make copies from your original key, not from another copy. If you have an original key that came with the lock or the vehicle, use it as the source for duplicates. Each time a key is copied from a copy, tiny inaccuracies build up, so a third- or fourth-generation copy can be noticeably worse than the first. Keeping a good original and cutting from it keeps every duplicate accurate.
When It’s the Lock, Not the Key
Sometimes a key that will not turn is not the key’s fault at all, it is the lock. A worn lock cylinder, dirt or debris inside, or a lock stiffened by a Calgary winter can all stop a perfectly good key from turning. If a brand-new, well-cut key still struggles, or if your existing key has gradually become harder to turn over time, the lock itself may need cleaning, lubrication, or repair. That is where door lock repair comes in, addressing the lock rather than cutting yet another key.
Get Keys That Just Work
The bottom line is that a key should turn smoothly the first time, every time, and if it does not, either the cutting or the lock needs attention. Precise cutting from a good original, on proper equipment, gives you keys you can rely on. It is worth having keys cut properly rather than settling for a copy that fights you at the door, especially for keys you use every day.
Frequently Asked Questions
Why won’t my newly copied key turn?
Usually because the cutting was imprecise, cuts slightly too shallow, too deep, or off position, so the pins in the lock do not align. It can also result from copying a key that was itself already a copy, which compounds errors.
Why should I copy from the original key?
Because each copy of a copy adds tiny inaccuracies. Cutting from an accurate original keeps every duplicate precise, while later-generation copies can become noticeably worse until a key eventually will not work.
Could the problem be my lock instead of the key?
Yes. A worn cylinder, dirt inside the lock, or a lock stiffened by cold can stop even a well-cut key from turning. If a new, properly cut key still struggles, the lock itself may need cleaning, lubrication, or repair.
Does key cutting quality really vary that much?
It does. Well-maintained equipment, quality blanks, and careful cutting from an accurate original produce a key that turns smoothly, while worn equipment and rushed cutting produce keys that stick or fail.
