Manhattan Access Control Installation —
Board-Ready. Audit-Trail Backed.
Manhattan's pre-war co-ops, high-rise office towers, and ground-floor retail require access control that satisfies co-op boards and building management — while delivering the audit trails, remote credential management, and fail-secure configurations that dense urban buildings demand.
Why Most Access Control Systems Fail
(and how we fix it)
A system with shared PINs, no audit trail, and no remote management isn't protecting your building — it's just a more expensive key.
Codes get shared and never changed. When something goes wrong, there's no record of who entered or when — making investigations impossible.
Improperly configured locks release during outages, leaving your building unsecured. Fail-safe vs. fail-secure decisions require understanding your fire code requirements.
A former employee or ex-tenant still has a physical key or working credential. You're either onsite to reprogram it or they still have access.
Complex admin software, no training, no documentation — managers who can't add a credential or pull a report without calling the installer back.
Every person gets their own fob, card, or mobile credential. Every entry attempt is timestamped and logged — giving you a complete record when you need it.
We configure lock behavior to meet NYC DOB and FDNY requirements for each door's function — and add UPS battery backup so short outages don't affect access.
Deactivate a lost fob or a former tenant's access in seconds from your phone — no reprogramming on-site required.
We configure the management dashboard, train your team, and leave you with documentation so you're never dependent on calling us back for routine admin tasks.
Transparent Pricing.
No Hidden Fees.
Pricing varies based on door count, hardware selection, and wiring complexity. Here's what most installs cost — with no surprises in the final invoice.
We Know Manhattan Buildings
Pre-war co-ops and condos in Manhattan often require board approval, building management sign-off, and coordination with the building's super before any work begins. We've navigated this process across the Upper West Side, Upper East Side, Downtown, and Midtown — and we provide the full documentation boards typically request: licensing, insurance certificates, and a detailed written scope of work.
High-rise office buildings and multi-tenant commercial spaces add another layer of complexity: elevator access control, server room restrictions, and multi-floor deployments where cables need to route through building core risers. We coordinate with building management and security teams to meet lease and compliance requirements — including NYC DOB and FDNY fire safety code.
Fully licensed low-voltage contractor. Proper credentials, proper insurance on every job.
We run cables through walls and ceilings — not surface-mounted along baseboards.
You own the system outright. No subscriptions, no cloud contracts, no lock-in.

What Our Clients Say
Verified Google reviews from property managers, business owners, and residents across NYC.
"We had a major problem with former employees keeping building access after they left. Seneca installed a key fob system that lets us deactivate credentials instantly. The install was clean, the training was thorough, and we've never had to call them back for help."
"Seneca installed access control for our 18-unit building and the difference is night and day. Every resident has their own fob, we can see the entry log remotely, and rekeying for a new tenant takes seconds. The install was done in a single day with zero tenant complaints."
"These guys know NYC buildings. They understood the co-op board process, brought the right documentation, and coordinated with our super. The system has been running flawlessly for over a year. I'd recommend them to any building in the city."
"We needed a multi-door access control system on short notice. Seneca came out the same week, gave us a clear proposal, and had everything running within two days. No surprises on the invoice, and the remote management portal they set up is genuinely easy to use."
