How much does intercom repair cost in Los Angeles?

Most LA intercom repairs land between $350 and $750, including parts like relays and transformers and the on-site labor. Diagnostic visits within our standard service area are free. Labor is billed at $225 per hour with a 2-hour minimum, and most repairs finish inside that window. A 3G to 4G cellular conversion is priced separately because the LTE kit alone runs $1,250. We give you a written quote on-site before any work starts, so there are no surprise charges.

Can you fix a 3G intercom that stopped working?

Yes. AT&T and T-Mobile shut down 3G in 2022, which killed thousands of older DoorKing, Linear, and Sentex callboxes across LA overnight. The fix is a 4G LTE conversion kit. We swap the cellular module, re-activate service through the manufacturer’s plan, reprogram the directory, and test the new connection. The callbox housing, wiring, and keypad usually stay in place.

Do you repair Aiphone wired commercial intercoms?

Yes. We service Aiphone IS, IX, GT, and JK series wired systems, which we see all over LA office and retail buildings. Common repairs are master station replacement, sub-station wiring fixes, and door release relay swaps. For older systems where parts are getting hard to find, we can wire in an IP gateway so the existing handsets keep working alongside a modern controller.

How long does a typical intercom repair take?

The diagnostic itself takes 30 to 60 minutes. About 60% of repair calls finish on the first visit because we carry common parts on the truck: transformers, relays, weatherproof housings, and replacement modules for the brands we work on most. Bigger jobs like a full callbox replacement or a multi-tenant directory rebuild usually run 2 to 4 hours.

Do I need to replace my whole intercom or can it be repaired?

Most of the time, repair is the right call. A failed transformer, a corroded keypad, or a stuck relay can be fixed without touching the rest of the system. Replacement makes sense when the unit is more than 15 years old, the parts are out of production, or the wiring is too far gone to patch. We tell you straight up which side of that line your system is on after the diagnostic.

Can you convert my old apartment buzzer to a video or app system?

Yes. We do this conversion regularly. The most common upgrade path is from a DoorKing 1812 or Linear AE-100 to a ButterflyMX or DoorBird D21 series for buildings under 30 units. For larger buildings we usually keep the existing conduit and pull new wire to a modern multi-tenant unit. App access, video, and remote unlock all come standard on the new generation.

Do you service apartment buildings, HOAs, and property managers?

Yes. We work with property managers and HOA boards across LA County on intercom repair, directory programming, callbox replacement, and 3G to 4G cellular conversions. We can hold a master copy of the tenant directory, push updates when units turn over, and bill at a property management rate for ongoing service. Send us your building details and we’ll set up a coverage plan.

What’s the difference between a video intercom and a telephone entry system?

A telephone entry system like the DoorKing 1812 dials the resident’s phone when a visitor presses a code at the gate. The resident answers on their cell or landline and presses 9 to open the gate. A video intercom adds a camera so the resident sees who’s at the door before unlocking. Modern IP video units like DoorBird and UniFi go a step further and route the call to an app on the resident’s phone.

Can you integrate my intercom with my electric gate?

Yes. We integrate intercoms with LiftMaster, DoorKing, FAAC, All-O-Matic, and Maximum Control gate operators. The intercom triggers a relay that fires the operator’s open command, exactly like a remote or keypad would. We do this integration as part of any electric gate install or repair and it works for swing, slide, and barrier arm gates.

Do you offer maintenance plans for commercial buildings?

Yes. Our commercial maintenance plan covers quarterly site visits, directory updates, firmware patches, relay and transformer testing, and priority dispatch when something fails between visits. Pricing scales with the number of entry points and brands on site. It’s the most cost-effective way to keep a multi-door office or industrial building running without surprise downtime.

Which intercom brand is best for a single-family home in LA?

For most LA homes, DoorBird is the top pick if you want premium build quality and HomeKit support. UniFi is the best value if you already run Ubiquiti for your network and cameras. LiftMaster works well if you already use MyQ for the gate and garage. We install all three and can walk you through which one fits your existing gear and your budget.

Can my old wiring be reused for a new intercom?

Often, yes. Most older wired intercoms run on 4-conductor or 6-conductor low-voltage cable, which can usually carry a modern IP video signal with a converter or a PoE adapter at each end. The exception is corroded or undersized wire, which we’d recommend pulling and replacing. We test the existing run during the diagnostic and tell you whether it’s worth keeping.

What Is an Intercom System? (And Why Modern Los Angeles Properties Need One)

An intercom system is a networked audio or video communication device used to control visitor access, monitor entry points, and manage security for buildings and properties. Los Angeles homes, HOAs, apartments, offices, retail shops, and industrial sites rely on wired and wireless intercoms for convenient, secure communication and entry management.

Types of Intercoms We Install & Service

Video Intercom Systems: Use an HD camera and two-way audio/video so you can see and talk to visitors before granting access. Ideal for home, business, and multi-tenant properties that want added security and a record of every visitor.
Telephone Entry Systems: These callboxes connect visitors with residents or offices via landline or cell phone. Doorking and Linear are the most common brands. No internet required—great for clients who want a set-and-forget solution.
Network-Based Intercoms: These modern systems use your WiFi or Ethernet network and can be controlled from a smartphone app. Works with brands like DoorBird, UniFi, and Ring. Flexible for retrofits and new installs, supporting both audio and video.
Multi-Tenant Intercoms: Designed for apartments, condos, and offices. Residents or staff can answer from inside, via mobile app, or even offsite. Directory-based for easy guest access and built-in keyless entry features.
Commercial & Industrial Intercoms: Rugged, weatherproof callboxes for high-use locations, employee entrances, or gated parking. Handles delivery management and can be programmed for multiple users or shifts.
Gate Intercom Systems: Connects directly to sliding or swing gates, garages, or parking entry points. Allows voice or video communication and remote opening, all integrated with your security system.
Property Manager & Building Intercoms: Cloud-managed and highly customizable for buildings with many users. Offers remote management, audit trails, PIN or code-based entry, and easy access for service vendors.

Common Intercom Problems We Fix in Los Angeles

Most intercom service calls in LA fall into a handful of repeat failures. Here’s what we see week after week, and what’s actually wrong when each one happens.

Callbox has no audio or no dial tone. Telephone entry systems like the DoorKing 1812 or Linear AE-100 stop dialing when the phone line dies, the speaker amp burns out, or the keypad ribbon cable corrodes. We test the line, swap the speaker board, and re-terminate the wiring at the callbox.
Intercom shows no sign of life. No lights, no beep when you press buttons, nothing. That’s almost always the power supply or the PoE injector that feeds the unit. In the worst case, the intercom itself has failed. We test the power feed first, then the PoE injector, then the unit if both check out.
Intercom powers up but shows offline. You hear the keypad beep, the LEDs come on, but the unit can’t be reached from the app or the receiver. That’s a network issue. We check the Ethernet run from the unit to the switch, the switch port itself, and the cloud handshake or firmware on DoorBird and UniFi units.
App can’t connect or push notifications stopped working. Smart intercom apps drop offline when the unit loses its cloud handshake after a router swap, a firmware update, or a Wi-Fi password change. We re-pair the device, update firmware, and reopen the right ports if the building uses a managed network.
Buzzer or relay won’t trigger the door strike. The intercom rings, you press the unlock button, and nothing happens at the door. That’s almost always a stuck relay, a blown transformer feeding the strike, or a broken wire run from the intercom to the lock. Diagnostic time: about 20 minutes with a multimeter.
Apartment directory wrong, or tenant calls go to the wrong unit. Usually one of three things: a programming issue (tenants turned over and nobody updated the callbox), a keypad failure that’s mis-reading the digits being pressed, or a memory issue on the controller where the dial-by-name table is corrupted. We pull the directory, run the keypad through a diagnostic, and reset the controller memory if we have to. Then we reprogram, push fresh tenant numbers, and label the wiring so the next tech doesn’t have to guess.
3G cellular sunset killed the callbox. AT&T and T-Mobile shut down their 3G networks in 2022. If your DoorKing 1830 series or older Linear callbox stopped working around that time, the cellular module is dead. The fix is a 4G LTE conversion kit. We swap the modem, re-activate service, and reprogram the unit.
Wired wear and corrosion at the gate or callbox. Outdoor callboxes in coastal LA take a beating. Salt air pits the keypad contacts, sprinklers seep into the housing, and 10-year-old wire splices oxidize. We rebuild the connections in a weatherproof junction box and reseal the housing.
Power supply or transformer failure. Most intercoms run off a 16VAC or 24VDC transformer mounted in a closet or panel. When it fails, the whole system goes dark. We carry replacement transformers and PSUs on the truck for DoorKing, Aiphone, and DoorBird.

If you’re reading this and one of these matches what your system is doing, call (310) 400-0314 and we’ll diagnose it on-site.

Apartment & Multi-Tenant Intercom Repair

We service apartment buildings, condos, and HOAs across Los Angeles, from 4-unit triplexes in West LA to 100+ unit complexes in Koreatown and Downtown. Property managers usually call us in two situations: an aging callbox finally died, or a building changed hands and the new owner has no documentation for the existing system.

Multi-tenant work is mostly directory programming. When tenants move in or out, the callbox needs the right name and dial code mapped to each unit. On a DoorKing 1834 or 1838 we can pull the directory, re-import it from a CSV, and have the new tenant calling correctly within an hour. On older Linear AE-2000 or AE-100 units we usually do it manually at the keypad.

The classic LA scenario: a building manager inherits an old DoorKing 1812 from the 1990s, the codes haven’t been changed in 15 years, half the tenants have keys to the front gate that nobody can account for, and the callbox is calling apartments that don’t exist anymore. We rebuild the directory, reset all access codes, and give the manager a clean spreadsheet of who has what.

For buildings still running on a 3G cellular buzzer system, we convert to 4G LTE so the callbox actually works again. Where the older wiring is too far gone to keep, we recommend swapping to a modern multi-tenant platform: ButterflyMX for app-based access in mid-size buildings, DoorKing for legacy phone-line directories, or DoorBird for smaller 4 to 12-unit properties.

If you manage a building and the intercom is acting up, send us a quick note with the make and model and we’ll let you know what the repair path looks like.

Commercial Intercom Installation & Repair

Our commercial work covers office buildings, retail storefronts, industrial yards, warehouses, and gated parking structures. The brand mix on the commercial side is different from residential. Aiphone is still the wired commercial standard in LA after 30 years on the market, and we see their IS, IX, and GT series in tenant-improvement jobs every month. For IP commercial deployments, 2N and Axis dominate because they integrate cleanly with enterprise access control.

Most commercial calls aren’t just about the intercom. They’re about how the intercom talks to the rest of the access system. We integrate intercoms with cloud-based access control platforms like Brivo, UniFi Access, and LiftMaster MyQ. That means a tenant can buzz in a delivery driver from their phone, log who entered, and revoke access remotely when an employee leaves.

We handle a single-door office intercom at a small studio in Culver City the same week we wire a four-entry industrial setup for a warehouse in Vernon. Same install team, same parts on the truck, just different scope.

If you’re running a Brivo or UniFi system already, the UniFi G4 Doorbell Pro is usually the fastest add. It speaks the same protocol as the rest of the system, the credentials sync automatically, and the install is clean. For older Aiphone wired systems, we either repair the existing units or wire in an IP gateway so the legacy stations can talk to a modern controller. Call (310) 400-0314 and we’ll walk through what fits your building.

Home & Residential Intercom Repair

For single-family homes and gated estates, the residential IP video intercom market in LA is dominated by three names: DoorBird, UniFi, and LiftMaster. DoorBird leads on build quality and the German hardware lasts a long time outdoors. UniFi wins on price and integration when the homeowner already runs Ubiquiti gear. LiftMaster’s smart video doorbells fit homeowners who already use MyQ for their gate or garage.

A lot of our residential work involves the driveway gate. The intercom at the street has to integrate with the gate operator so a visitor can buzz the house, the homeowner answers from their phone or a wall station, and the gate opens with a single tap. We do this integration as part of any electric gate installation or repair job, and it works across LiftMaster, DoorKing, FAAC, and All-O-Matic operators.

Smart home integration matters too. DoorBird talks to HomeKit, Alexa, and Google Home out of the box. UniFi sits inside the UniFi Protect app. LiftMaster runs through MyQ, which now has a HomeKit bridge. We set this up at install time so the homeowner gets a notification on their phone, sees the visitor, and triggers the gate without leaving the couch.

The most common residential request right now: replacing a 1990s wired Aiphone handset system. The handsets fail, the wiring corrodes, and the parts are getting hard to find. We pull the old gear and install a modern IP video unit, usually a DoorBird D2101V or a UniFi G4 Doorbell Pro, on the same wire run when the conduit allows it.

Intercom System Components, Locking Hardware, and Smart Features

Entrance Panels: These are the outdoor-facing intercom units installed at entry points. Most are weatherproof and vandal-resistant, with stainless steel or alloy construction and anti-tamper features. Premium panels may include built-in HD video, name directory, keypad, and proximity reader in one unit.
Tenant/Resident Stations: Indoor devices or wall screens used to answer intercom calls. Can be basic audio handsets or touch-screen video panels. Newer models support mobile app notifications, allowing residents or staff to answer from anywhere.
Electric Strikes & Deadbolts: These replace or work alongside mechanical locks. An electric strike lets you unlock a door or pedestrian gate remotely, either from your phone, an app, or a desk station. Common for lobby doors and gates.
Maglocks & Magnetic Locks: High-strength magnets hold doors/gates securely closed until released by intercom or code. Popular in commercial buildings and for emergency exit setups due to their strong holding power and low maintenance.
Smart Keypads & Proximity Readers: Enable staff, tenants, or vendors to gain entry with a PIN code, key fob, or access card. Integrates with your intercom for multi-factor security. Reduces the need for traditional keys.
RFID & NFC Access: Offers seamless, touchless access using RFID cards, key tags, or even smartphones with NFC. Each use can be logged for audit purposes, ideal for high-traffic commercial sites.
Motion Sensors & Contact Sensors: Detects door or gate status (open/closed), or motion near entry points. Enables automatic lighting, security alerts, or scheduled locking/unlocking based on activity.
Integration Relays & Network Switches: Allows your intercom to control other systems, like gates, maglocks, or even video surveillance. Works with platforms such as Brivo, UniFi, and LiftMaster for total access control integration.
Cloud & Mobile App Control: Lets you manage entry permissions, receive notifications, view video, and unlock doors remotely. Especially valuable for property managers, Airbnbs, and anyone needing flexible access control.

What an Intercom Repair Visit Looks Like

Here’s how a typical repair call runs from start to finish, so you know what to expect when you book one.

Phone call. You call (310) 400-0314 or fill out the form. We ask for the make and model if you know it, what’s failing, and where you are. Most calls take 5 to 10 minutes to scope.
Diagnosis and quote. For straightforward issues we can quote a price range over the phone. For anything we need eyes on (wiring, dead callbox, integration with an existing access system), we book a diagnostic visit.
Same-day or next-day appointment. Most LA jobs we can hit within 24 to 48 hours during standard business hours. We book a 2-hour arrival window.
On-site diagnostic. Typical diagnostic runs 30 to 60 minutes. We test power, verify wiring continuity, check the callbox or door station hardware, and confirm the relay path to the lock or gate. By the end of the visit you have a written quote.
Repair on the spot when possible. Our trucks carry the parts we use most: 16VAC and 24VDC transformers, replacement relays, weatherproof callbox housings, common DoorBird and UniFi modules, and basic wire and conduit. About 60% of repair calls finish on the first visit.
Warranty. Labor is warrantied for 1 year on new installations. Parts carry the manufacturer warranty, which is usually 1 to 2 years for DoorBird, DoorKing, and UniFi.

Intercom Repair Pricing in Los Angeles

Pricing depends on what’s broken, how the building is wired, and which brand we’re working on. Here’s what most LA jobs land at, so you know roughly what to budget before you call.

Diagnostic visit: Free within our standard LA County service area.
Common repair (relay swap, wiring fix, callbox rebuild): $350 to $750. Covers most “the buzzer stopped working” calls.
3G to 4G LTE cellular conversion: The LTE conversion kit itself runs $1,250. Total install cost depends on the existing wiring condition and how close the callbox is to an active electrical outlet. Cellular service plan billed separately.
New IP video intercom installation (single-family home): $1,500 to $6,500. Covers a DoorBird D2101V or UniFi G4 Doorbell Pro with mounting, wiring, app setup, and gate or strike integration.
Multi-tenant intercom replacement: $1,500 to $7,500. Most multi-tenant jobs involve running new wires through metal conduit in parking lots or risers, which drives the upper end of the range.

Labor is billed at $225 per hour with a 2-hour minimum. Most repair calls fit inside that 2-hour window.

Travel surcharges may apply for jobs outside our standard LA County coverage. Pricing also shifts when site access is tight (rooftop callbox, locked riser room, restricted parking) or when the existing wiring needs to be rerun.

Permits may be required depending on your property and the work scope. Ask us during your estimate and we can point you toward the right city department to check with.
