An in-house system built for NYC buildings
248 Lock is a proprietary lock system designed and backed by Safety Locksmith & Hardware. Unlike third-party brands, every aspect of the system — the hardware, the keyway, the blanks, and the cutting process — is controlled entirely by our team. That means when you install a 248 Lock, you know exactly who can service it and who can duplicate the keys. There are no other sources.
It was designed with the NYC residential market in mind — durable enough for high-traffic apartment buildings, precise enough for co-op entry doors, and backed by the kind of long-term service relationship that a neighborhood locksmith can provide and a national brand cannot.
What makes 248 Lock different
Exclusive key control
248 Lock keys can only be duplicated by our team — no exceptions. No hardware store, no online service, no other locksmith can make a copy.
Built for NYC
Designed around the lock preparations, door types, and usage patterns common to Upper West Side residential and commercial buildings.
Single-source service
Installation, maintenance, rekeying, and key duplication all handled by the same team — no handoffs, no ambiguity about who's responsible.
Who 248 Lock is right for
248 Lock is a strong choice for property owners and managers who want complete confidence in who has key access to their building or unit. Because duplication is exclusively controlled by our team, adding or retiring keys is always a deliberate, traceable process — not something that can happen at a hardware store without your knowledge.
It suits buildings where the landlord or super needs to maintain a clear record of key holders, residential units where the occupant wants genuine key control without the cost of a premium high-security brand, and any property where the owner wants a single, reliable point of contact for all lock-related needs.
Exclusively serviced by us
If you have a 248 Lock installed and need a key duplicated, there is only one place to go — our store at 1713 2nd Ave on the Upper West Side. This isn't a limitation — it's the point. The system is designed so that key access is always controlled, always intentional, and always traceable back to a service relationship with a team you know.
Not sure if your lock is a 248 Lock? Bring your key in and we'll identify it on the spot. If it is, we can duplicate it same-day and advise on any service or upgrade needs.
