Why a Copy of a Copy Stops Working

A key works because each cut sits at a depth that lifts one pin to exactly the right height. Those depths are specified in thousandths of an inch, and every duplication introduces a small error — the tracer follows a groove that is already slightly worn, the cutter leaves its own tolerance, and the new key comes out a fraction shallow or deep.

One generation of that is invisible. Two is a key that needs a small wiggle. By the third the key is measurably wrong, and the lock it was cut for might tolerate it while a second lock on the same key will not. That is the exact reason a key opens the front door but not the back door — the two cylinders have slightly different wear and only one of them forgives the error.

The fix is to stop copying copies. Cut from the earliest, least worn key you own, or better, decode the lock and cut a fresh key to its actual specification. A key cut to code is not a copy of anything; it is a new original.

Blanks, Keyways and Why the Right One Matters

The blank is the uncut key, and its cross-section — the pattern of milled grooves along the blade — has to match the keyway of the lock or the key will not enter. There are many hundreds of keyway profiles in general use, and a great many of them look nearly identical to the eye while differing by a fraction where it counts.

A blank that is close but not correct will sometimes force into a lock and appear to work. It also drags on the wards every time it goes in, wearing both the key and the lock, and it is a common reason a key snaps months later. If a key needs pressure to enter a lock it has always fitted before, something is wrong with either the blank or the cylinder.

Cheap blanks are a false economy

Blank quality varies enormously. Soft brass alloys cut beautifully and wear fast; a soft key rounds off within a year of daily use and starts failing in the very lock it was cut for. Nickel silver holds an edge far longer and costs a little more. On a key carried daily on a ring with other metal, that difference is the whole service life.

Keys Cut to Code — No Original Needed

If every key to a lock is lost, the lock still knows its own combination. Reading it — either from a code stamped or recorded for that cylinder, or by decoding the pin stack directly — lets us generate a key that fits without replacing anything. This is routine work and it saves the cost of new hardware, which is why it is worth asking about before anyone suggests a whole new lock.

It applies to more than house doors. Filing cabinets, desk pedestals, tool chests, lockers, cabinet locks, window locks and mailbox locks are all usually code-cuttable, and many of them carry a code number stamped on the lock face or on the plug. If you can read a number off the lock, write it down before calling — it can turn a decode into a two-minute cut.

Padlocks and small cam locks are the most common code-cut requests we get, largely because nobody sells replacements for a thirty-year-old cabinet and nobody wants to drill a piece of furniture.

Keyed Alike, and How Many Keys a Household Needs

Most homes here have between two and four exterior openings — front, back, garage service door, sometimes a screened porch — and most people end up carrying a different key for each. Bringing them onto one key is done by repinning the cylinders to a shared combination, not by cutting a strange key that half-works in all of them, and it is a same-visit job on standard hardware.

The trade-off is honest and worth stating: one key opening every door means one lost key compromises every door. For most families that is the right trade, because the alternative in practice is that the awkward back door simply never gets locked. For a household where a lodger or a regular visitor holds a key, keeping the garage or a store room on a separate key is the sensible split.

• Two working keys per adult, plus one spare kept off the property
• A spare cut from the freshest key you own, not from your daily one
• One key per exterior door only where access genuinely needs separating
• Never keep the only spare inside the house it opens
• Retire a key by rekeying, not by hoping it stays lost

Reading Wear on Your Own Keys

Lay a suspect key next to a rarely used one from the same lock. The peaks and valleys on a worn key are visibly rounded where the fresh one has crisp edges, and the tip is often shortened. A rounded key sits a fraction low in every chamber, and every lock it enters tolerates that a little less each year.

Keys wear fastest on a heavy keyring. The weight hanging off an ignition or a lock cylinder puts a bending load on the blade every day, and keys carried loose in a pocket with coins abrade steadily. Splitting a big ring into a house ring and a vehicle ring extends the life of both sets, and it means losing one does not lose everything.

The other thing worth checking is the shoulder — the step where the blade meets the head. That is where keys snap, and a visible crack or a noticeable flex there means the key is finished. Get a replacement cut before it breaks in a lock, because extraction is a service call and a fresh key is not.

Keys We Cannot and Will Not Copy

Restricted and patented keys cannot lawfully or practically be duplicated without documented authorisation from the registered system owner. If your key is stamped with a manufacturer's restriction and a system number, the copy has to go through the dealer holding that registration. We will explain what your key is if you are unsure, and we will not cut it regardless of how the request is framed.

We also decline to copy a key on request from someone who is not entitled to it — a key handed over by a tenant for a landlord's master, a key belonging to an employer, a key to a property the person cannot demonstrate a connection to. This is the least popular paragraph on any locksmith's website and it is the one that makes the rest of it mean anything.

Small Keys, Odd Keys and the Ones People Give Up On

A large part of key cutting is not house keys at all. It is the small awkward keys attached to objects nobody sells replacements for, and the usual answer people get elsewhere is that it cannot be done.

• Filing cabinet and desk pedestal keys, usually code-stamped on the lock face
• Locker and gym cabinet keys, often a simple flat blank
• Window latch and sash lock keys, frequently a single common pattern
• Tubular keys from vending machines, bike locks and some cabinet locks
• Barrel and cruciform keys found on older furniture and equipment
• Antique bit and lever keys for chests, wardrobes and interior doors

Tubular keys — the round ones with cuts arranged in a circle — need a specific machine rather than a standard key cutter, which is why most counters turn them away. They are straightforward for anyone who has the equipment, and they can usually be decoded from the lock if the key is gone entirely.

Antique and bit keys

Old furniture and interior doors in older houses use lever locks and warded locks that take a bit key: a shaft with a flag on the end. These are cut by hand from a blank chosen to clear the wards, and it is patient work rather than machine work. It is also the difference between using a wardrobe and looking at one.

Bring the lock if it is removable, or a clear photograph and a measurement if it is not. For anything with a code stamped on it, write the code down exactly, including letters — a single transposed character produces a key that will not enter.

Where We Cut

We work across Eglin, Valparaiso, Niceville, Shalimar, Fort Walton Beach, Ocean City and Wright, and we cut at the property. That matters for code cutting and decoding, which need the lock, and it matters for keyed-alike work, which needs every cylinder in the same place at the same time.

We are a licensed and insured locksmith company operating in Florida. Every key we cut is tested in the lock it was cut for before we leave, from both sides where relevant. A key that has not been tested in its own lock is a guess, and we do not hand those out.
