DoorKing Keypad & Intercom Repair: The Pasadena Owner’s Guide
DoorKing keypad and intercom repair in Pasadena typically runs between $180 and $420 installed, depending on whether we’re replacing the keypad face, the circuit board, or the full intercom housing. Most jobs are completed same-day because we keep DoorKing-compatible parts on the truck. The usual discovery point is a keypad that stopped recognizing a code that worked yesterday, or an intercom where the call button lights up but nothing actually rings inside the house.
We see this across Pasadena driveways, from the hillside gates off San Rafael Avenue to the flat lots near Caltech. The keypad gets hammered by sun exposure, and the intercom’s microphone picks up dust and moisture. By the time an owner calls us, they’ve usually tried a new code, checked the breaker, and maybe given the faceplate a firm press. That’s the right instinct. The next step is matching the part to the exact DoorKing model, because not everything swaps cleanly across series lines.
Which DoorKing Models This Applies To
DoorKing has been making telephone entry and keypad systems for decades, and the parts landscape is split across three main lines: the 1800-series telephone entry systems, the 6000-series gate operators with integrated keypads, and the standalone 1500-series keypads. The compatibility gotcha is that a keypad face from a DoorKing 1812 will not drop into a 1838 housing without a wiring adapter, and the 1515 keypad uses a different mounting plate than the 1514. If you can read the model number off the inside of the housing, we can usually match the part over the phone before we dispatch.
On the OEM-versus-aftermarket question: DoorKing’s own replacement boards are well made and carry a manufacturer warranty, but they’re priced accordingly. We stock both OEM and quality aftermarket equivalents from suppliers we’ve vetted over years of Pasadena service calls. For a 20-year-old intercom, a $65 aftermarket keypad membrane often makes more sense than a $140 OEM replacement. For a newer 1838 that handles visitor logging, we lean OEM because the aftermarket boards sometimes drop that feature. We’ll put both options in writing before any work starts, so you’re choosing with the prices in front of you.
Signs Your DoorKing Keypad & Intercom Repair Is Failing

- Intermittent code acceptance. The keypad works in the morning but not the afternoon, which usually means the membrane contacts are degrading from heat cycling. Pasadena summers accelerate this, especially on west-facing gates that catch the full afternoon sun.
- Call button lights but no ring inside. The intercom’s relay or speaker driver board has failed. This is the most common DoorKing intercom fault we replace, and it’s almost always the board, not the house wiring.
- Static or one-way audio. You can hear the visitor but they can’t hear you, or the audio crackles constantly. The microphone element corrodes over time, particularly on gates near irrigation overspray or morning marine-layer moisture.
- Keypad beeps but doesn’t trigger the gate operator. The keypad is sending output, but the relay on the control board isn’t closing. On DoorKing systems, this is frequently a failed relay or a cold solder joint on the board, not a programming issue.
- Display shows odd characters or is completely dark. The LCD driver or the backlight inverter has failed. On the 1838 series, a dark display often still works as a keypad, but you lose the menu feedback that tells you the code registered.

AfterReplacement Cost & What’s Included
Here’s what DoorKing keypad and intercom work runs in Pasadena, installed:
| Repair Type | Parts Range | Labor Range | Typical Total |
|---|---|---|---|
| Keypad membrane/face replacement | $45-$85 | $65-$110 | $110-$195 |
| Control board replacement | $90-$180 | $85-$140 | $175-$320 |
| Intercom speaker/mic element | $35-$75 | $65-$110 | $100-$185 |
| Full keypad/intercom housing swap | $140-$260 | $110-$160 | $250-$420 |
The price you get from us is the price you pay. We write the parts cost and the labor range down before we touch a screwdriver, per Haven Standard Clause 1. That price holds unless we open the housing and find something genuinely different, and in that case we stop, photograph it, and call you before proceeding. Every repair includes a photo log of what came out, what went in, and the final button test, plus our 365-Day Done Right Promise on the work.
DIY or Call Us?

There are a few things you can safely check before calling anyone. Confirm the breaker hasn’t tripped, verify the keypad isn’t locked out from too many incorrect codes (DoorKing keypads will lock for 60 seconds after repeated failures), and if you have a multimeter, check for 24 volts at the keypad terminals. Those checks take five minutes and rule out a third of the calls we get.
Beyond that, you’re opening a housing with 24-volt control wiring and soldered board connections. If you short across the wrong terminals, you can take out the gate operator’s main control board, and that’s a $300 repair on top of the keypad fix. We’ve seen it happen on do-it-yourself attempts off East Washington Boulevard. If you’d rather skip the risk, call us at (626) 624-4196. For the keypad itself, same-day replacement is usually realistic. For intercom board work, same-day holds if the part is a model we stock; otherwise it’s next-day once the board comes in.
FAQs
Most DoorKing keypads last 8 to 12 years in Pasadena’s climate before the membrane or board gives out. Gates facing west toward the Arroyo burn through keypads faster, often in 5 to 7 years. The intercom microphone is usually the first component to fail, sometimes within 4 years on gates near irrigation mist. Call (626) 624-4196 and we’ll tell you if your model is in the typical replacement window.
We repair what’s repairable: loose ribbon cables, corroded terminals, and individual relay failures are fixable without replacing the whole unit. A failed membrane or a cracked circuit board is a replacement job because those parts aren’t economically rebuildable. The determining factor is always what we find when the housing opens, and we’ll photograph it either way.
A straight keypad or intercom swap takes about 45 to 90 minutes on site, including testing and the photo documentation. If we’re also reprogramming entry codes or re-terminating corroded wiring at the gate operator, budget two hours. We carry a range of DoorKing-compatible parts on the truck so most calls are one visit.
We keep common DoorKing keypad membranes, control boards, and intercom elements stocked locally in Pasadena, along with parts for LiftMaster, Mighty Mule, and Ghost Controls systems. For less common DoorKing series components, we can usually have the part in hand within one business day. Same-day service is realistic for the parts we carry, which covers most residential DoorKing keypad failures.
