House Key Duplication for Staten Island Homes
Our residential key duplication service is built for Staten Island homeowners, renters and landlords who need extra copies of house keys that actually work the first time. Hardware-store kiosks cut keys from a worn original, so every copy drifts a little further from the factory cut. We decode your key to its original bitting and cut a fresh blank to spec, which is why our duplicates turn smoothly in the lock instead of sticking or needing to be jiggled.
We duplicate every type of key found around a Staten Island home: standard Kwikset (KW1) and Schlage (SC1) house keys, deadbolt keys, mailbox and storm-door keys, padlock and shed keys, garage side-door keys, and high-security restricted keys such as Medeco and Mul-T-Lock, provided you can show you are the authorized keyholder. Need copies for a rental unit, a nanny, a dog walker or a contractor? We can cut several at once and label each set so you know exactly who holds which key.

How Our Key Duplication Works
1. We Identify the Key
Our technician checks the keyway, brand and any "Do Not Duplicate" or restricted markings. If a key is on a restricted system we verify authorization before cutting, which protects you as the homeowner.
2. We Decode and Cut
Instead of tracing a worn key, we read its depths and cut a new blank to the original factory code on a calibrated machine. Most house keys take under five minutes per copy.
3. We Test in Your Lock
Because we come to you, every copy is tested in the actual door before we leave. If a lock is worn or sticking we can lubricate or repair it on the same visit.

24/7 Availability
Lost your only house key at night? We can cut a new key from the lock itself, around the clock, anywhere on Staten Island.

Mobile Service
Our van carries hundreds of blanks, so we duplicate keys at your front door and test them in your lock on the spot.
Duplicate the Key or Rekey the Lock?
Duplication is the right choice when you simply need more copies of a key you trust. If you have just moved into a home in Staten Island, lost a key, or taken one back from a former tenant or contractor, copying the existing key only multiplies the problem, because anyone who still holds an old copy can walk in. In that situation we recommend rekeying the lock so old keys stop working, then cutting fresh copies of the new key. We can do both in a single visit and it usually costs less than replacing the locks.
Landlords across Staten Island neighborhoods from Great Kills to St. George also use our service to keep a labeled master set for each unit, so tenant turnover never leaves you scrambling for a working key.
Frequently Asked Questions
How much does it cost to duplicate a house key in Staten Island?
Standard Kwikset or Schlage house keys are inexpensive, usually just a few dollars per copy, plus a mobile service fee if we come to you. High-security or restricted keys cost more because the blanks are controlled. We quote the total before cutting.
Can you copy a key marked "Do Not Duplicate"?
The stamp itself is not legally binding, but restricted keyways like Medeco and Mul-T-Lock require proof that you are the authorized keyholder. Bring ID and, if you have it, the key control card, and we can cut the copy.
Can you make a key if I do not have one to copy?
Yes. We can decode the lock cylinder or impression a new key directly from the lock, so you get a working original even if every copy has been lost. This is a common 24/7 call for us.
Why does my hardware-store copy not work?
Kiosk machines trace the worn key you hand them, so each generation of copy drifts further from the factory cut. We cut to the original code instead, which is why our duplicates work smoothly and do not wear out your lock.
Do you come to my home to duplicate keys?
Yes. Our mobile service covers every Staten Island neighborhood, typically arriving within 15 to 30 minutes, and we test each copy in your own door before we leave.
