DoorKing Keypad & Intercom Repair: The Los Angeles Owner’s Guide
DoorKing keypad and intercom repair in Los Angeles typically runs $280-$620 installed, depending on whether the fix is a simple keypad membrane replacement or a full intercom station swap with programming. We stock the most common DoorKing keypad and intercom components on our service trucks, and most repairs are completed in a single visit the same day you call. Homeowners usually discover the problem when the keypad stops accepting codes, the intercom goes silent, or the gate simply stops responding to any access command on a rainy January morning.
Which DoorKing Models This Applies To
DoorKing has manufactured access control equipment in Southern California since 1948, and their product lines span several decades of installations across Los Angeles. The most common keypad and intercom units we encounter in the field are the 1800 series (1802, 1803, 1808) and the newer 1830/1833 models, plus the telephone entry systems like the 1810 and 1812 series used in multi-tenant buildings from Pasadena to Pacific Palisades.
To identify your unit, check the label inside the keypad housing or on the intercom base station. The model number and serial number are stamped on a metal plate or printed on a weatherproof sticker. For the 1802 and 1803 stand-alone keypads, the part number is usually visible once you remove the two screws securing the front cover. The 1812 intercom systems have the label on the main control board, accessible after releasing the housing latch.
We carry both OEM DoorKing parts and quality aftermarket equivalents that meet the same voltage and communication specs. For the 1800-series keypads, aftermarket membrane switches often outlast the originals because the silicone rubber formulation has improved since those units were first manufactured. For intercom systems, we generally recommend OEM replacement boards to ensure clean integration with existing telephone lines and programming.

Signs Your DoorKing Keypad & Intercom Repair Is Failing
- Keypad buttons require multiple presses or feel mushy. The silicone membrane beneath the buttons degrades after years of UV exposure in Los Angeles sun, particularly on south-facing gates in neighborhoods like Silver Lake and Echo Park where reflective heat accelerates material breakdown.
- Intercom calls connect but audio is garbled or drops out. This points to a failing audio transformer or corroded connection terminals, common in coastal zones like Marina del Rey where salt air infiltrates the housing seals.
- Gate opens intermittently or not at all, but the motor runs fine. The keypad or intercom relay board is sending weak or interrupted signals. On DoorKing 1810 systems, the dry-contact relay often fails before the main logic board.
- Backlight works, but no response to any code or call button. The microcontroller or power regulation circuit has failed. This is more frequent on units installed before 2010 that have not had their electrolytic capacitors replaced.
- Water visible inside the housing after rain. The gasket seal has failed, and moisture is attacking the circuit board. In the San Fernando Valley, where Santa Ana winds drive fine dust against housing seams, gasket deterioration happens faster than manufacturers typically rate.
Replacement Cost & What’s Included
| Repair Type | Typical Range (Los Angeles) | What’s Included |
|---|---|---|
| Keypad membrane replacement (1802/1803) | $280-$380 | Part, removal/install, code reprogramming, seal check |
| Full keypad assembly swap | $340-$480 | New housing, board, membrane, mounting hardware, programming |
| Intercom station repair (board/component) | $320-$520 | Diagnosis, part replacement, line testing, audio calibration |
| Complete intercom system replacement | $480-$620 | New unit, wiring inspection, programming, homeowner walkthrough |
What drives the range: the age of your existing unit, whether the wiring harness is reusable, and whether your system uses the older two-wire or newer multi-conductor communication protocol. We settle on an upfront price before touching a single bolt, and every repair carries our 90-Day Done Right Promise. If it is not right, we come back and make it right. No paperwork, no arguing.
DIY or Call Us?
There is a safe middle ground here. A homeowner can check whether the keypad housing screws are tight, whether the wiring conduit has pulled loose from ground settling, and whether the breaker feeding the low-voltage transformer has tripped. These checks cost nothing and solve the problem more often than people expect.
What does not belong in DIY territory: opening the control board housing while power is present, attempting to solder relay connections, or reprogramming the access codes without understanding the master reset procedure. DoorKing intercom systems run on 16-24 VAC, which will not kill you but can damage the board if you short the wrong terminals. More importantly, a miswired repair can leave your gate in an open or unlocked state without you realizing it.

FAQs
Twelve to eighteen years is typical for keypad membranes, and fifteen to twenty years for intercom boards, though direct sun exposure and coastal salt air shorten that by 20-30 percent. Units installed on north-facing gates or with overhead shade covers usually reach the higher end of the range. Call (833) 754-7503 for an exact assessment of your unit’s condition - estimates are free.
Often yes, if the failure is isolated to the membrane, a single relay, or a connection terminal. We always diagnose first and recommend repair when it is the sound choice. If the main processor or power supply has failed, replacement is usually more cost-effective than chasing intermittent board-level faults. Call (833) 754-7503 and we will tell you straight which path makes sense.
Most DoorKing keypad and intercom repairs are completed in one to two hours on-site, including programming and testing. If we need to order a specialty part for an older 1802 or 1810 series unit, turnaround is typically two business days. Same-day service is available throughout Los Angeles when you call before noon.
We stock the most common DoorKing keypad membranes, relay boards, housing gaskets, and intercom components on every service vehicle. For the nine brands we service - LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule - we have found that carrying inventory is the only way to finish jobs in a single visit, which is what we promise.
A gate should open when you need it to and stay closed when you don’t. Everything else is just the work. If your DoorKing keypad or intercom is giving you trouble, call (833) 754-7503. A live person answers twenty-four hours a day, seven days a week. We will give you an upfront price, show up when we say, and stand behind the repair with a written 90-Day Done Right Promise.
