Most office keys copy only after the person who controls that door says yes, and only if the blank is available. A kiosk refusal is not a diagnosis. Start with the owner or manager, then have a licensed locksmith inspect the actual key.
| Key situation | Usual first step | Typical next step |
|---|---|---|
| Ordinary employee key, common blank, manager approved | Hardware store or locksmith duplicate | Test in the lock; stop if it binds |
| Worn original | Stop tracing copies | Locksmith inspects key or cylinder; may code-cut, rekey, or replace |
| Electronic credential (fob, card, smart lock code) | Building access-control admin | Revoke or issue in software; this is not a metal-key copy |
| Restricted or marked controlled keyway | Owner or dealer of record | Authorized cut only with their process; kiosks usually cannot help |
| Lost or unreturned key | Assume copies may exist | Rekey or change credentials with the controller’s approval |
Why an office key often will not copy at a kiosk
The machine may not recognize the key, the blank may not be stocked, or the store may refuse marked keys. None of that proves a copy is impossible elsewhere.
Record every word, letter, number, and logo on the key. Photograph the head markings if you need to describe them, without posting cut geometry publicly. Note which door it opens. Do not put the building address on a loose tag.
Ask the property manager whether that door belongs to the tenant, the owner, or a shared system. Suite, lobby, parking, and utility keys can have different controllers.
When you need to copy building keys, separate three questions:
- Who controls access to that door?
- What exact key system does the building use?
- What proof does the approved source require?
A licensed locksmith can inspect the physical key and explain duplicate, authorized-source, or rekey paths.

What DO NOT DUPLICATE and restricted keyways actually mean
“DO NOT DUPLICATE” is a policy marking. It is not automatically a patent number. This site’s research did not confirm a California statute that makes the stamp, by itself, either always illegal or always ignorable. Ask the owner or manager.
A genuine restricted keyway follows that system’s current dealer rules. “High security key copy” as a search phrase does not identify the keyway. Use the exact markings and building records.
Do not order a blank from appearance alone. Ask for the system name and the approved duplication process.
Who has to authorize a copy in a leased building
The building owner or property manager sets authorization. Swift Key San Diego does not grant permission. The matched locksmith should not guess who controls the door.
Ask in writing: who may authorize another key for this exact door? Permission for a suite key may not cover the lobby or the garage.
If you are an employee, go through your supervisor or facilities contact. If you are a tenant, use the lease contact. If you are the owner, gather system records first.
Do not hand an unidentified building key around for trial copies. Log each authorized duplicate and the door it serves.
What a licensed locksmith asks for before cutting
Documents are not universal. ID, company card, manager email, or a system authorization card may all be relevant. None replaces the building’s own approval.
Bring the original key when permitted. Photographs of markings help a first conversation; the professional may still need the key in hand.
Rekeying, repair, and installation are locksmith work, not a hardware-store copy of a working key. Check licensing through the state’s license search. Ask for the LCO. Swift Key San Diego is a referral service, not a locksmith company.
For access changes beyond a spare, use the commercial locksmith referral page.
When a rekey or a master system beats more copies
Another duplicate fits when the access plan is still correct and you only need one more approved key. More copies do not fix lost keys or unclear records.
Consider rekeying when a key is unaccounted for or occupancy has changed. The owner or manager still approves the scope. Tenant turnover is a planning moment, not an automatic copy for the next occupant. See commercial lock rekeying after tenant turnover.
A master key system may fit when roles need different doors. List openings and roles, not only employee names. See the business master key system guide.
Ask for the proposed scope in writing. Confirm price and any warranty with the independent locksmith. Swift Key San Diego does not set those terms.
