Why Copies Fail

Four Reasons That Hardware-Store Key Never Worked

A key that sticks is almost never bad luck. It is one of these, and all four are avoidable.

It Was Copied From A Copy

Every duplicate loses a little accuracy. Three generations in, the key is measurably different from the one the lock was built for.

The Blank Was Close, Not Right

A blank with the wrong keyway profile will still cut and still go in the lock. It will just never turn smoothly.

The Machine Was Not Calibrated

Duplicators drift. A shop that cuts keys all day checks the alignment; a machine in the corner of a big-box store often does not.

Nobody Read The Wear

Copying a worn key faithfully copies the wear. We cut to what the lock actually wants, which is why old keys come back working better.

About Harkness

Forty-One Years On The Same Corner

Harkness opened in 1985 and has cut keys from the same counter ever since. That longevity is mostly why the wall behind it holds around nine hundred blanks — four decades of not throwing anything away means we still stock profiles that were discontinued before most hardware chains existed, which is exactly what you need when the key is for a 1970s filing cabinet or a lock nobody makes any more. The rest of the job is unglamorous: a machine that gets calibrated, a person who looks at the wear on your key before cutting, and a standing offer to cut it again for nothing if it does not turn. That is the whole business.

Do Not Duplicate

What That Stamp Actually Means

Probably the most misunderstood thing in this trade, and the reason people get turned away for no good reason.

It Is Not A Legal Restriction

"Do Not Duplicate" stamped on an ordinary key carries no legal force. It is a request, not a lock — which is why it protects far less than people assume.

Most Shops Refuse Anyway

Big-box stores decline on sight because it is simpler than making a judgment. That is why you have been turned away three times.

We Ask Instead

We check you are entitled to the key — ID and something linking you to the property or business. Then we cut it, because you own the lock.

A Genuinely Restricted Key Is Different

Patented keyways with controlled blanks cannot be cut by anyone without authorisation from the system holder. We will tell you which one you have.

Odd Keys

The Ones Everyone Else Says No To

A good share of what crosses this counter has already been refused somewhere else. Desk and cabinet keys from the sixties and seventies, where the blank was discontinued decades ago and the only route is cutting to the lock's code. Barrel and tubular keys for vending, lockers and bike locks. Skeleton and bit keys for interior doors in old houses, which have to be filed rather than machined. Sailboat, tractor and plant keys where the original was lost and the lock has never come off the machine. None of it is exotic to us — it is just slower than a house key, and it needs a wall of old blanks and somebody willing to look at the lock rather than the key.

How A Visit Goes

In, Cut, Tested, Out

There is no appointment system because there does not need to be one.

1

Bring The Key

Or the lock, if every key is gone. A photo is not enough for cutting, though it is enough for us to tell you if we stock the blank.

2

We Match The Blank

Profile matched from the wall rather than the nearest thing that fits, which is the single biggest reason copies fail.

3

Cut And Deburred

Cut on a calibrated machine, then the edges cleaned so it does not chew your lock on the first few turns.

4

Tested Before You Pay

In your lock if you brought it, on a gauge if you did not. If it ever fails to turn, bring it back and we cut it again free.

Been Turned Away?

Bring Us the Key Nobody Else Would Cut

Restricted stamps, discontinued blanks, odd shapes, worn originals. Forty-one years of blanks on the wall and a willingness to actually look at it.

Minneapolis Reviews

Keys That Finally Turned

Three hardware stores told me my key could not be copied because it said Do Not Duplicate. Harkness explained what that stamp actually means, checked I was the keyholder, and cut two. Ten minutes and a proper explanation instead of a shrug.

I inherited a roll-top desk with one worn key that barely turned. He read the wear pattern, cut a fresh key to what the lock actually wanted rather than copying the worn one, and it works better than it has in decades.
Curtis FairbanksAntique key · Northeast
Took in eight different padlocks from the cabin, the shed and the boat and asked if they could all take one key. Twenty minutes later they did. I have carried one key instead of eight for two summers now.

Before You Visit

Key Cutting, Answered Plainly

Why does my hardware-store key stick?

Almost always one of three things. It was cut from a copy rather than an original, so it inherited two generations of small errors. Or the blank was a near-match on profile rather than the right one — it will still cut and still enter the lock, it just will not turn cleanly. Or the machine was out of calibration, which happens quietly to duplicators that nobody checks. Bring the sticking key and the original if you still have it, and we will tell you which of the three it was.

Will you copy a key stamped Do Not Duplicate?

Usually yes, and the reason is that the stamp carries no legal weight on an ordinary key — it is a request printed on metal, not a restriction. What we do instead of refusing on sight is check that you are entitled to it: photo ID plus something linking you to the property or business. If it turns out to be a genuinely restricted key on a patented keyway with controlled blanks, that is different, and we will explain who has to authorise it rather than send you away confused.

Can you cut a key if I have lost all of them?

Often, yes. If the lock has a code stamped on it, or is a make we can decode, we can originate a key from the code rather than copying anything. For most cabinet, desk and padlock locks it is straightforward. For house locks we usually need the cylinder brought in or the lock removed, since reading the code means taking it apart. It costs more than a duplicate and it takes longer, but it is nearly always cheaper than replacing the lock.

Can all my padlocks take one key?

If they share a keyway family, yes — we repin them to a common combination so one key opens all of them. It is one of the most satisfying jobs we do: people bring in the shed, the gate, the cabin and the boat and leave carrying a single key. Padlocks that are sealed, or that belong to different manufacturers with incompatible keyways, cannot join the set, and we will separate those out before starting rather than after.

Do you cut car keys?

We cut the mechanical blade for most vehicles, which is what you need for an older car or a spare that only has to open the door. What we do not do is program transponders or proximity fobs, because that is a different job with different equipment. If your car needs the chip paired to the immobilizer, we will say so and point you to an automotive locksmith rather than sell you a blade that will open the door and never start the engine.
