Commercial Key Duplication
Duplicate restricted or standard commercial keys for your Greenville SC business. Also called commercial key cutting, we cut copies for most commercial key types on site, including authorized copies of restricted keyways.
About this service
Commercial key duplication carries a different set of problems than copying a house key. A business is usually managing far more keys in circulation at once: front doors, suite doors, storage rooms, and equipment cabinets, each needing copies for staff, managers, and cleaning crews as people come and go. Many commercial buildings also use restricted or patented keyways, high-security systems like Medeco or Abloy, where duplication legally requires an authorization card or is limited to the locksmith of record on file for that property. We verify authorization before cutting a restricted key, keep a record of who has copies, and can cut standard commercial keys on the spot for offices, retail spaces, multi-tenant buildings, and franchise locations. This is a separate service from residential key duplication and from automotive key duplication: this covers the keys that open your business, not your home or your vehicle.

Common Causes of Commercial Key Duplication
New staff needing their own key at hire
Offices and retail locations regularly need fresh copies cut as new employees start, rather than passing around a single shared key.
Staff turnover leaving unreturned keys unaccounted for
When an employee leaves without returning their key, a business often needs new copies issued under tighter tracking, sometimes alongside a rekey.
A multi-tenant building needing consistent copies across units
Property managers overseeing several tenants often need standardized key duplication so every unit and common area is tracked the same way.
A franchise location opening or expanding
New franchise locations frequently need a batch of keys cut to match the corporate standard for staff, managers, and vendors.
A restricted keyway requiring authorized copies
Buildings on a patented or high-security keyway need every additional copy to go through proper authorization instead of a standard hardware store cut.
A key ring being split for different access levels
A business consolidating or reorganizing which staff carry which keys often needs several duplicates cut at once.
An existing key wearing down from daily commercial use
Keys used dozens of times a day by staff wear faster than a house key and are often duplicated proactively before they fail.
A vendor, cleaning crew, or contractor needing temporary access
Businesses working with outside vendors or cleaning services sometimes need a tracked copy issued for the duration of that relationship.
The Risks of DIY Commercial Key Duplication
Restricted keyways cannot legally be cut by a hardware store or kiosk
Patented keyways are specifically designed to block unauthorized duplication, so a kiosk or general hardware store has no legal way to cut a copy even if the blank looks similar.
No authorization tracking with a walk-in copy
A key cut without verifying authorization leaves no record of who now holds a copy, which undermines the entire point of using a restricted system.
Standard kiosks are not calibrated for commercial-grade cylinders
Commercial hardware often uses tighter tolerances than residential locks, and a generic kiosk cut can bind or wear out fast in high-use commercial doors.
No system for tracking who has keys to which door
Without a locksmith-maintained record, a business loses track of exactly which staff, vendors, or former employees still hold a working key.
Assuming a franchise or multi-tenant building can use one generic process
Different units or locations under one business may be on different keying systems, and treating them all the same risks cutting a key that does not match.
A lost restricted key without a documented recovery plan
If a restricted key is lost and there is no authorization record on file, recovering control of that keyway can mean a costly full rekey of the affected doors.
Wrong blank selected for a similar-looking commercial brand
Commercial key blanks from different manufacturers can look nearly identical while using different internal profiles, leading to a copy that never seats correctly.
No verification that the person requesting a copy is actually authorized
A walk-in duplication service has no way to confirm the requester works for the business or is entitled to a key, which is a real liability for restricted-access properties.
What Affects the Cost
- Key type (standard commercial keyway vs. restricted or high-security keyway)
- Whether authorization verification is required before cutting
- Number of copies needed for staff, vendors, or multiple units
- Blank availability for less common commercial brands

How it works
- 1
Bring your original key or authorization
Standard commercial keys just need the original. Restricted keyways require an authorization card or verification that you are on the authorized list for that key system.
- 2
Keyway and authorization check
We confirm whether the key is a standard commercial profile or a restricted, patented keyway that requires sign-off before cutting.
- 3
Cutting the duplicate
Keys are cut on calibrated commercial equipment, matched precisely to the brand and keyway rather than a rough visual copy.
- 4
Test and record the copy
Every duplicate is tested in the actual lock, and we keep a record of restricted key copies issued so your business has a paper trail.
