Professional Key Duplication in Midtown Manhattan
ASK Locksmith maintains one of the largest key blank inventories in NYC — over 1,000 blanks covering virtually every residential, commercial, and padlock key manufactured. Walk in and walk out with a perfectly cut duplicate in minutes. No appointment needed for standard keys.
Standard Key Duplication
We cut duplicates for Kwikset, Schlage, Yale, Corbin Russwin, Sargent, and every major residential and commercial brand. Bring your original key and we'll have a precise copy cut and checked while you wait. Standard key duplication takes 5–10 minutes.
Mul-T-Lock Key Duplication
As an authorized Mul-T-Lock dealer, we cut and duplicate the full range of Mul-T-Lock cylinders — MT5+, Classic, Interactive+, and more. Mul-T-Lock's patented key control means duplicates can only be made by authorized dealers. If you're already in our system as a key holder, we can cut a duplicate immediately. New customers will need to establish an account.
Medeco Key Duplication
Medeco's high-security keys feature patented angled cuts that require specialized cutting equipment and authorization. As a Medeco authorized dealer, we have both. Bring your card of authorization and a valid ID — we'll have your key cut and verified the same visit.
Restricted & Patented Key Blanks
Beyond Mul-T-Lock and Medeco, we stock restricted blanks for Assa Abloy, Kaba, Best/BEST Access, Primus, and other commercial-grade systems. Restricted key duplication requires proof of authorization from the key holder of record — typically the building owner or manager.

Key Duplication FAQ
-
Standard key duplication starts at a few dollars per key. High-security keys (Mul-T-Lock, Medeco) cost more due to the specialized blanks and cutting process. We quote the price before cutting — no surprises.
-
For most locks, we can cut a key by code if you can provide the lock or the key code number. If neither is available, we can disassemble and decode the lock cylinder to cut a working key. Call us to discuss your situation.
-
No appointment needed for standard key duplication — just walk in during business hours. For large orders (10+ keys) or restricted key systems, calling ahead helps us confirm stock and prepare.
-
"Do Not Duplicate" is a request, not a legal restriction in New York — any locksmith can technically cut the key. However, keys with genuine restricted patents (Mul-T-Lock, Medeco, etc.) physically cannot be duplicated without proper authorization and specialized equipment.
-
We test every key before you leave the shop. If a key we cut doesn't work in your lock, bring it back and we'll recut or refund — no questions asked.
