CONTROLLED ENTRY
Access control installation, repair and system upgrades for offices, apartment buildings and commercial entrances across Nassau County, Suffolk County and NYC. Plan card-reader, key-fob, keypad or compatible mobile entry around your doors and users. Request a free on-site installation estimate.

770 Doors & Windows installs, repairs and upgrades door access control systems across Nassau and Suffolk County. A system can manage one office door or multiple entrances using cards, key fobs, PIN codes or compatible mobile credentials. We assess the entrance hardware, power, wiring and user permissions together so the proposed system fits how your property operates.
For a new installation, send the number of doors and users, your town or ZIP, and entrance photos. For a fault, describe whether the reader responds, the lock releases and the door closes. Call (347) 541-4824 to confirm same-day service availability and the appropriate appointment.
We start with a door-by-door survey. Door material, frame condition, the existing latch, closer and exit hardware affect the locking options. We then review where readers and controllers can be mounted, the cable route, power supply capacity and any network connection. An electric strike and a magnetic lock need different preparation; the release and exit arrangements are reviewed for the actual property.
| Entry option | What to decide before installation |
|---|---|
| Cards and key fobs | Who receives credentials, who can deactivate a lost fob, and which doors each user can open. |
| Keypad entry | Individual versus shared codes, access schedules and the process for changing access when a user leaves. |
| Mobile or remote entry | Compatible phones and readers, network requirements, administrator ownership and any manufacturer subscription. |
| Intercom integration | How visitors reach a resident or receptionist and how an authorized call releases the correct entrance. |
For an office, define staff hours, delivery access and restricted rooms. For a shared residential building, separate resident credentials from visitor calling. For a storefront or other commercial entrance, review daily door traffic and opening schedules. These are planning options, not a promise that every product supports every function.
Often some components can remain, but compatibility needs checking. Send model labels for the reader, controller, power supply and locking hardware. We check credential formats, controller capacity and the condition of existing wiring before proposing reuse, a partial upgrade or replacement.
The written scope should identify equipment, cable work, door hardware, programming, user setup and training. Confirm software fees and other trades separately. Door count, wiring access and the condition of the entrance affect price and timing; a photograph alone cannot establish every installation requirement.
Before handover, test approved credentials, agreed schedules, visitor release and the installed exit controls. Confirm normal closing and re-engagement, explain how to remove a lost credential, and record who owns the administrator account. Keep the agreed model details and support information with the property records.
For a new access control installation in Nassau or Suffolk County, start with the number of doors and users, the entrance hardware and who will manage credentials. We review readers, key fobs, keypads, controllers, cable routes, power and authorized release together before specifying a system.
The written scope should identify equipment, wiring, programming, user schedules and administrator handover. Existing locks, controllers and wiring can remain only when compatible and in suitable condition. Confirm software fees and related trades separately. Testing includes authorized credentials, exit controls, normal closing and relocking.
Service coverage includes Nassau County and Suffolk County. Send the town or ZIP and photos so we can confirm the work and schedule. Call (347) 541-4824 or request service. Never send private access codes or passwords.

An access-control proposal should list each controlled entrance, its lock and release hardware, the required reader or keypad and the approved user groups. For NYC and Long Island properties, this makes equipment selection and programming reviewable before work begins. Handover should identify who administers users and how the completed doors were tested.
It should explain the included door hardware, power equipment, cable work, controller capacity and setup. Confirm any network, account or ongoing service requirements for the proposed system as part of the agreed scope.
Door count, credential type, reusable hardware, cable routes and programming requirements shape the installation estimate.
The written scope should identify the approved work, included equipment and any separate work before you authorize the job.
Provide the number of entrances and users, property type, desired entry methods and photos of existing door hardware.
Include the property address or ZIP and who can provide access.
ACCESS CONTROL
The opening, lock and release hardware.
Key fobs, cards, keypads and permissions.
User changes, schedules and handover.
Same-day service: call to confirm availability for your ZIP code, job scope and required parts. New system installations may need a separate appointment. Free on-site estimate. Work and pricing are explained before you approve.
Start with the number of controlled doors, the users who need access and who will manage changes. An office may need staff schedules and a way to remove a lost credential. A residential entrance also needs a visitor plan. We identify the reader, controller, power and locking interface as one scope.
The existing door must close and latch reliably. We inspect the door, frame, closer and release hardware before recommending equipment. Product selection, emergency exit arrangements and any work by another trade are reviewed for the actual property; one lock type is not suitable for every entrance.
We install card-reader, key-fob and keypad entry for Brooklyn apartment buildings, offices and commercial entrances. For a new system, send the neighborhood or ZIP code, number of doors, approximate user count and photos of the entrance. We review cable routes, power, locking hardware, visitor access and who will manage credentials before preparing the installation scope.
A shared residential entrance may need resident credentials and a compatible visitor intercom; an office may need staff access schedules and a process for removing lost fobs. See access control installation in Bensonhurst or installation in Crown Heights for local service information. Use the neighborhood directory below for other Brooklyn locations.
If an existing reader, controller or power supply has stopped working, start with access control repair. Diagnosis determines whether a component repair is practical. A new installation or system replacement is a separate scope, discussed before any upgrade is approved.
For Nassau and Suffolk projects, send the town, ZIP code, entrance photographs, door count and approximate user count. Tell us whether you are replacing keys, adding another door to an existing system or installing a new system. Model labels and information about existing network equipment help define the next step.
If visitors also need to call residents or reception, compare intercom installation on Long Island with the planned credential system. A failed reader or door release on an existing entrance can be assessed through access control repair before a complete new installation is proposed.
The approved scope should identify credential setup, schedules, administrator ownership and training. Test authorized entry, the agreed exit method and the normal door-closing cycle. Confirm how staff or management will add users, remove lost credentials and obtain help with the selected system.
Often, but the door, frame, closer, lock preparation and proposed release device need to be checked for compatibility and condition.
Yes. Send the office location, door count and approximate user count. We review the entrance and how access permissions will be administered.
The answer depends on the door and frame, existing latch, exit arrangement and project requirements. We review the actual entrance before specifying hardware.
A compatible intercom can connect to an approved release interface. The intercom, controller, power and locking hardware should be planned together.
Call to confirm availability. Some service work can be scheduled the same day; a new system may need equipment, wiring work and a separate installation appointment.
A useful specification identifies the door, required entry methods, connected systems and who will administer users. Product options from different manufacturers should be compared against those requirements before ordering.
If you already have equipment or are considering a product from another country, send the model number, product link and photos. We can review the proposed installation, compatibility and any additional work before accepting the scope.
Access control must work with the physical door before software features matter. We identify the door and frame material, existing lock, handing, traffic pattern and release requirements. That information guides the choice between an electric strike, magnetic lock or another compatible locking method, along with the reader, controller and power supply.
The scope can also include credential management, request-to-exit devices, door position monitoring and intercom integration. We plan cable routes and equipment locations around the property, then explain how users will enter, exit and be added or removed from the system after installation.
Call or send photos with your ZIP code. We confirm availability and arrange an inspection when needed. We explain the recommended work and price before you approve the job.
Card reader installation and key fob entry system installation need a plan for credential administration. Magnetic lock installation and electric strike installation use different mounting and locking approaches. Equipment must be selected for the actual entrance and release requirements.
Access control installation cost depends on the number of doors, cable routes, locking hardware, power and management features. Confirm any manufacturer subscription separately from installation work.
A final price requires the actual scope. Call or send photos and your ZIP code to discuss the next step.
Send photos and your ZIP code, or call 770 Doors & Windows directly.
Start with a list of entrances, who uses each one and the hours when access is needed. A shared lobby, staff door and equipment room can require different permissions. Include how visitors and deliveries are admitted.
Before an upgrade, identify the existing readers, credentials and administrator account. Compatibility depends on the actual models and configuration; an existing card is not automatically compatible with a replacement reader.
