Key Duplication Services
Mobile Key Duplication in Milwaukee and Waukesha
Affordable Locksmith LLC offers mobile key duplication for homes and businesses throughout Milwaukee and Waukesha Counties. Our appointment-based service helps you create spare keys on-site without visiting a shop. We support property owners, tenants, and office managers who need working duplicates for daily access or emergency use.
We do not copy car keys or electronic key fobs. However, if you need spares for residential doors, shared offices, or padlocks, our mobile team can help during a scheduled visit.
Keys We Can Copy

We recommend that all homeowners make duplicates of their house keys so they always have a spare or two to leave with a trusted neighbor or friend.
We cut new copies for most standard residential and commercial key types, including:
- Household keys used for front doors, side entries, garage doors, or storage spaces
- Office and tenant keys used for suites, interior offices, break rooms, or shared spaces
Depending on the key size, condition, and brand, we can duplicate keys for your mailbox, cabinets, suitcases, safe, lockbox, and padlocks. Standard compatible keyways include Schlage, Kwikset, and other major lock types. If your key is bent or worn and it’s the only copy, we suggest rekeying the lock so it works with a new key.
Keys marked “Do Not Duplicate” will only be copied with written authorization.
What to Expect from an On-Site Visit
We inspect the original key during your appointment to confirm it’s suitable for duplication. A clean, undamaged original increases the chance of a properly working copy. Our team uses calibrated equipment to cut the duplicate at your location and test the new key when access is available to confirm it works.
We cannot make a copy if the original key is missing or unusable. We can often rekey the lock to work with a new key and make duplicates. Please let us know in advance if that may be required so that we can bring the right tools.
We also support batch duplication for property managers or business owners who need several spares across multiple locks. This service is useful in multi-tenant buildings, employee-only areas, and other locations that require shared access.
When Extra Keys Are Helpful
Key duplication supports convenience and peace of mind. Common reasons people request copies include:
- Adding roommates, employees, or contractors
- Keeping backup keys in a lockbox, desk, or with a trusted neighbor
- Preparing for future lockouts by having a spare on hand
If you’ve recently moved into a new property, we recommend rekeying your locks and cutting new keys instead of duplicating any that may have been handed out previously.

FAQs About Duplicating Keys For Local Businesses and Homes
Can you duplicate a key if I don’t have the original key?
No. Key duplication requires the original key. We recommend rekeying the lock and creating new keys based on updated lock pins if it’s lost or missing.
Do you copy keys marked “Do Not Duplicate”?
We do not copy keys marked “Do Not Duplicate” unless you provide written authorization. In many cases, rekeying the lock is a better option for secure key replacement.
Can you make multiple key copies in one visit?
Yes. We can create multiple duplicates of house keys, office keys, or padlock keys during the same service appointment. Let us know the quantity when scheduling.
What if the original key is worn or bent?
If the original key is damaged, we may not be able to copy it accurately. In these cases, we recommend replacing or rekeying the lock and cutting new keys from fresh pins.
Can you duplicate office keys used in shared suites or businesses?
Yes. We duplicate office keys for business properties, shared access points, and interior doors. Please have the original key available during the visit.
Do you copy mailbox, cabinet, or padlock keys?
Depending on the brand and model, we may be able to duplicate mailbox or padlock keys. Send us a photo or bring details during scheduling to confirm compatibility.
Will you test the new keys after duplicating them?
Yes. If we have access to the lock, we check that the new keys turn properly. An accurate fit helps maintain long-term door security and convenience.
Do you duplicate car keys or key fobs?
No. We do not copy car keys, program transponders, or work with key fobs. We recommend contacting the dealership or a provider specializing in automotive keys for vehicle-related services.
Can I request key duplication during a lock installation or rekeying service?
Yes. If you’re already booking rekeying or lock installation service, let us know in advance if you need additional keys created during the same visit.
Why choose Affordable Locksmith LLC instead of a self service kiosk for key duplication?
Self service kiosks may offer convenience, but they often produce lower-quality duplicates that may not work smoothly in your lock. Affordable Locksmith LLC uses precision-cutting machine tools and inspects the original key before duplication to ensure each copy fits and turns correctly. We also provide on-site testing when possible, which kiosks cannot do. This helps prevent key failures and ensures reliable access for your home or business.
