Upper West Side Locksmith & Keys
High-Security Locks — Upper West Side Locksmith
High-security locks on the Upper West Side — Mul-T-Lock, Medeco, and restricted keyways installed. Call (646) 469-7112.
A standard deadbolt keeps honest people out. High-security locks keep everyone else out too: drill-resistant cylinders, pick-resistant mechanisms, and keys that cannot be copied at a corner hardware store. Upper West Side Locksmith & Keys installs Mul-T-Lock, Medeco, and other restricted-keyway systems across the neighborhood.
Restricted keyways are the real upgrade — your keys are cut only with your authorization, on file with us, so you finally know exactly how many copies exist. We fit high-security cylinders to your existing mortise or deadbolt hardware wherever possible, preserving the door's look while upgrading its strength.

Frequently asked questions
What makes a lock high-security?
Patented restricted keyways (keys cannot be copied without your authorization), pick and drill resistance, and bump-proof mechanisms. Mul-T-Lock and Medeco are the benchmarks we install.
Can you fit a high-security cylinder in my existing lock?
In most cases yes — high-security cylinders retrofit into standard deadbolts and many mortise locks, so the door keeps its look.
What is a restricted keyway?
A key design whose blanks are sold only to authorized dealers. Anyone with your key cannot walk into a hardware store and copy it — duplication requires your authorization on file.
Are high-security locks worth it for an apartment?
If you have ever wondered how many copies of your keys exist, yes. Restricted keyways end that uncertainty completely.
Do you sell Mul-T-Lock products?
Yes — we stock and install Mul-T-Lock cylinders, deadbolts, and padlocks, and we cut authorized duplicates.
