Key duplication copies a working key onto a new blank; key origination creates a key from scratch when no working copy exists. Locksmith pros handle both for house, vehicle, mailbox, cabinet, and padlock keys, cutting to precise tolerances so copies work smoothly for years. When you call, we connect you with an independent local locksmith pro who confirms what your key requires and quotes you directly before any work begins. We never quote prices ourselves.
The pro first identifies the key: its blank profile, keyway, and whether it carries electronics such as a transponder chip. For a standard mechanical key, they select a matching blank, trace or decode the original's cuts, and reproduce them on cutting equipment calibrated to the manufacturer's specifications. A careful pro then deburrs the new key and tests it in the lock when possible, because a copy that works is the only acceptable outcome. Quality matters more than people expect: a copy of a copy of a copy drifts from factory dimensions, which is why pros often prefer to decode a worn key back to its original factory specification and cut a fresh key to code rather than tracing the wear. For transponder-equipped vehicle keys, duplication also includes cloning or programming the chip so the engine recognizes the copy. Every element is confirmed with you, and quoted directly, before cutting begins.
Duplication requires a working key to copy; the original supplies the pattern. Origination means making a key when no working copy exists, and it is a fundamentally different service. To originate, the pro determines the correct cuts from the lock itself, from a code stamped on the lock or documented by the manufacturer, or through authorized key-data channels, then cuts a fresh key to that specification. Origination is common for vehicles with all keys lost, mailboxes and file cabinets whose keys vanished years ago, padlocks, desks, and older door locks. Because origination involves decoding rather than tracing, it takes more skill, more time, and often ownership verification, since the pro is effectively creating access where none existed in your hands. The practical takeaway: while you still have one working key, duplication is available and simple. Once the last key is gone, you are in origination territory, so make the spare early.
Kiosks and hardware counters are fine for basic house keys on common blanks. A locksmith pro is the right choice when accuracy, unusual blanks, or electronics are involved. Worn keys are the classic case: a kiosk traces the wear and produces a copy that works poorly or not at all, while a pro can decode the key back to factory specification and cut to code. Restricted and do-not-duplicate keys are another: patented, key-control systems require authorization, and a pro handles them legitimately or explains why they cannot be copied. Vehicle keys with transponder chips need cloning or programming that retail counters often cannot complete correctly, and most vehicles sold since the late 1990s carry immobilizers, so an unprogrammed copy opens doors but will not start the engine. Mailbox, cabinet, safe-deposit-style, and antique keys use blanks kiosks rarely stock. Finally, if the copy must work the first time, a pro tests it in your lock.
Blank availability comes first. Common residential profiles are stocked everywhere, while older, foreign, or specialty profiles for cabinets, mailboxes, and vintage locks may require sourcing. Key condition matters: a crisp original copies cleanly, while a worn or previously copied key benefits from being decoded to code, which takes more expertise. Electronics change the job substantially; transponder cloning, remote-fob pairing, and proximity keys each add equipment and procedure, with complexity varying by vehicle make and year. Restricted key systems introduce authorization steps by design, since their whole purpose is controlled duplication, and legitimate copies flow through documented channels. Origination difficulty depends on whether a code exists: a code-stamped cabinet lock decodes quickly, while an uncoded lock must be read from the mechanism itself. High-security laser-cut vehicle blades require milling equipment beyond standard duplicators. Quantity, testing each copy in its lock, and travel for mobile service round out the variables the pro folds into a direct quote.
For duplication, bring the working key itself, not a photo, and the cleanest original you have; copying the least-worn key in the household produces the most accurate result. For restricted or do-not-duplicate keys, bring whatever authorization applies, such as documentation from the property manager or system owner. For origination, bring proof you control the lock: ID plus registration for a vehicle, ownership or lease papers for a home, or the file cabinet, desk, or padlock itself when it is portable. Note any code stamped on cabinet locks, padlock bodies, or original key envelopes, because a code can turn a slow decoding job into a quick cut. For vehicle keys, know the year, make, and model, and say whether you want remote functions included. Decide how many copies you need and for whom. If the key operates something you cannot bring in, ask about mobile service so the pro can test copies on site.
The biggest is postponing the spare until the last key is lost, converting a simple duplication into an origination job at an urgent moment. A close second is copying from a copy: each generation drifts further from factory dimensions until keys stick, jiggle, or fail in cold weather, so always duplicate from the original or ask the pro to cut to code. People also assume a photographed key or a broken key is useless, when a pro can often decode either; bring all the pieces. Vehicle owners frequently buy uncut blanks or fobs online that turn out incompatible, or get a mechanical copy cut without the chip work, then discover the engine will not start. Others ignore do-not-duplicate stamps and are surprised when legitimate shops decline; restricted systems have proper authorization channels. Finally, few people test new copies in every relevant lock before filing them away, and an untested spare is not really a spare.
| Factor | Why it matters |
|---|---|
| Duplication versus origination | Copying a working key is quick because the pattern exists in your hand. Originating a key with no working copy means decoding the lock or sourcing key data, verifying you control the lock, and cutting from scratch. That difference in skill and time is the primary driver of scope. |
| Cutting to code versus tracing | Tracing reproduces your key as it is, wear included. Cutting to code restores the factory specification, producing a copy more accurate than the worn original. Code work takes decoding expertise and reference data, and it is often the sensible choice when the only available key is heavily worn. |
| Blank type and availability | Common residential blanks are stocked universally, while specialty profiles for mailboxes, cabinets, padlocks, older doors, and foreign vehicles may require ordering. High-security laser-cut vehicle blades additionally require milling equipment beyond a standard duplicator, which fewer providers operate. |
| Transponder cloning and programming | Most vehicles sold in the United States since the late 1990s include engine immobilizers, an anti-theft technology recognized by NHTSA, so a useful vehicle key copy includes chip cloning or programming, not just cutting. Procedure length varies by make, model, and year. |
| Restricted and controlled key systems | Patented key-control systems restrict duplication by design, and legitimate copies require authorization through the system's documented channels. The controlled parts and verification steps that make these keys hard to copy casually also add legitimate steps for authorized duplication. |
| Quantity, testing, and mobile service | Cutting many copies, testing each one in its lock, and traveling to you rather than working at a counter all extend the visit. Consolidating the household's key needs into one appointment is usually more efficient than piecemeal trips, and the pro can quote the batch as a whole. |

Yes, that is origination. The pro decodes the lock itself, reads a stamped code, or uses authorized key-data channels to determine the cuts, then produces a fresh key. Expect to show proof that you own or control the lock, and mention a lost-key situation when you call.
Every traced copy inherits the previous key's wear and cutting error, and the drift compounds with each generation until keys stick or fail. The fix is duplicating from the original or having the pro cut to factory code, which resets the key to its intended dimensions.
Only through proper channels. Restricted and patented key systems exist to control who can obtain copies, and legitimate providers require authorization from the system owner, such as a landlord or facility manager. A pro can explain the authorization path for your specific system.
Only if the electronics are handled. Most vehicles built since the late 1990s carry immobilizers, so the copy needs its transponder cloned or programmed in addition to accurate cutting. A mechanical-only copy will open doors but leave the engine immobilized.
We never quote prices. Scope depends on duplication versus origination, blank availability, whether cutting to code is needed, any transponder work, and quantity. The independent local pro confirms what your key requires and quotes you directly before cutting anything.
