Commercial locksmith & intercom installer in the Upper East Side
The Upper East Side is one of the neighborhoods our mobile technicians work in most. For co-op boards, supers and managing agents here, that means a truck with the cylinders, closers and intercom parts is usually close by, 24/7.
Buildings we work in
The Upper East Side mixes building types block by block:
- Pre-war co-ops on Fifth, Madison and Park with doormen, service entrances and decades-old master key systems
- Post-war white-brick and newer rental towers on First, Second and York Avenues
- Walk-ups and smaller rentals in Yorkville and on the side streets
- Medical and professional offices in building ground floors
- Boutiques and stores along Madison, Lexington and Third

What we do most in the Upper East Side
- Restricted Mul-T-Lock master keys for co-ops: Mul-T-Lock
- Service-entrance and basement steel doors: hollow metal doors
- Video intercom upgrades for walk-ups without a doorman: ButterflyMX
- European hardware in renovated apartments: European hardware
- Suite locks and access control for medical offices: access control
Co-op boards here often ask us to tighten key control: restricted keys only the building can order, a master key for staff, and records of who holds what. We set that up and keep it intact as residents change.
Mobile technicians, on site in the Upper East Side
We don't need a storefront. Our mobile technicians come to you in the Upper East Side with the trucks stocked for doors, locks and low voltage, so most jobs are surveyed, quoted and finished on site. When a part has to be ordered or imported, the written estimate says so.
Phone service is 24/7 at 212-837-4444, for every trade: doors, locks, intercoms, access control and safes.
