DoorKing Keypad & Intercom Repair: The Arlington Owner’s Guide
If you’re in Arlington with a DoorKing keypad that’s gone dead, a card reader that quit reading, or an intercom that crackles more than it talks, here’s the short version: we stock DoorKing-compatible keypads, intercom boards, wiring, and weather seals on our truck, and the installed price for most keypad or intercom repairs in Arlington runs between $185 and $420 depending on the model and what actually failed. We’ll match the part to your system, quote the job before we turn a screw, and stand behind the work for 90 days. The discovery moment is never graceful: it’s usually a delivery driver standing at the gate with groceries, your daughter forgetting her code for the fourth time, or rain the night before and a keypad that now thinks every button is the number nine.
Almost every DoorKing call we get starts with one of two stories. Either the keypad’s been outside for twelve years and the sun finally ate the membrane, or somebody installed a new keypad on a control board that was never designed to talk to it. Both are fixable. One of them should have never happened.
Which DoorKing Models This Applies To
DoorKing is the brand we see most often on Arlington’s older gated neighborhoods east of Cooper and around the country roads north of I-30. The main players are the 1812 Classic (the small black or silver pedestal keypad), the 1814 MicroPLUS, the 1816/1818 Access Plus series, and the 6050/6100 telephone entry systems on apartments and small HOA entries. Each one has a different board, a different wiring topology, and a different way the keypad or intercom ties into the main controller.
Here’s the gotcha that catches people: a DoorKing 1812 keypad will not reliably run on an Access Plus board even though the plug looks close. The wiring may even seat, but the communication protocol takes a different path and it’ll ghost-press buttons or refuse to transmit codes on cold mornings. We’ve unwired more than one of those in Arlington and had the homeowner tell us, “It worked fine for six months.” It didn’t. It just failed slowly enough to look like luck.
OEM DoorKing parts are widely available, and for keypads, we generally stick with genuine DoorKing or a Northeast Texas-proven aftermarket equivalent specifically cross-listed for the series. The difference matters more on Access Plus than on the older 1812 series: the microprocessor in the newer units is picky about voltage thresholds. If you’re not sure what you have, take the cover off (it’s usually four screws) and look for the silver model plate near the bottom of the enclosure. Snap a photo with your phone before you call, and we can tell you over the phone what you’re dealing with.
Signs Your DoorKing Keypad or Intercom Is Failing
- Buttons need to be pressed twice, or not at all. The carbon pads under the membrane wear unevenly, and the # and * keys usually go first because drivers lean on them with a thumb while holding groceries. This is repairable on most 1812 units, but the fix holds better with a new membrane than a cleaned one.
- The gate opens when nobody’s entered a code. More often than not, that’s a short to ground in the keypad wire, usually where it exits the pedestal and rubs the mounting flange. We see it all the time in Arlington after a storm pushes the wire against the post and starts bridging the circuit. It’s not a ghost; it’s bare copper touching metal.
- You hear scratchy or garbled speech from the intercom, or the visitor hears silence. The speaker terminals in the 1816 intercom boards corrode over time, especially in humid Texas springs. The board may still be fine; a good cleaning and re-seating of the spade connectors resolves a lot of these before we ever touch a replacement part.
- The keypad works, then dies after rain. The weather seal on the keypad body degrades and UV turns the rubber gasket brittle. Once moisture gets in and sits against the board overnight, you get intermittent failures that are heat- or humidity-dependent, which is exactly what we’ve been seeing more of in Arlington the last five years.
- Your code doesn’t work, but the keypad still beeps. That’s typically the master code chip or the relay output starting to go, or a programming mismatch after a power outage. If you’ve recently had a brownout or the control board reset, the keypad may have defaulted to factory settings without you knowing.
Replacement Cost & What’s Included
For most single-family DoorKing keypad replacements in Arlington, you’re looking at $185 to $320 installed. That includes the new keypad or intercom board, the labor to swap it, wire inspection and re-termination, and reprogramming your existing codes or setting up new ones. Telephone entry systems run a little higher, usually $290 to $420 installed, because there’s often an intercom speaker, a separate power supply, and a call-forwarding module involved. If it’s just a membrane overlay or a speaker cone, the price lands at the lower end.
| Repair Type | Typical Installed Range in Arlington | Typical Time |
|---|---|---|
| Keypad membrane replacement (1812/1814) | $85 - $150 | Same trip |
| Complete keypad replacement (single-family) | $185 - $320 | 1 - 2 hours |
| Intercom board repair or replacement | $250 - $390 | 1.5 - 2.5 hours |
| Telephone entry / Access Plus swap | $290 - $420 | 2 - 3 hours |
Every quote is written down before we start, and the price on the invoice matches the price you approved. No trip charge inside the county. No discovery fee, no “well, this turned out to be more than we thought.” If it’s more than we thought, that’s our problem, not yours. And every job carries the 90-Day Done Right Promise in writing: if it’s not done right, one call brings us back, no runaround.
DIY or Call Us?
You can safely do a few things before calling: check the breaker, look for an obvious chewed or waterlogged wire at the base of the pedestal, and pull the keypad cover to see if water or ants got inside. That’s all fine. But once you’re inside that cabinet with a multimeter, you’re one crossed wire away from turning a $75 repair into a $450 controller board replacement. DoorKing systems run on low-voltage logic that’s sensitive to shorts and miswired grounds, and a momentary wiring mistake can fry the very board that runs the whole gate. There’s no shame in knowing where to stop.
If you’re near South Arlington or anywhere in Tarrant County, just give us a call at (817) 241-4067. We’ll tell you over the phone whether it sounds like a membrane, a board, or a bad wire, and we’ll come out and put eyes on it before we ever ask you to spend a dime.
FAQs
In our experience, 8 to 12 years, depending on sun exposure. A keypad on a west-facing gate off Pioneer Parkway bakes every afternoon, and those membranes harden and crack years earlier than one shaded by a tree line near Viridian.
Sometimes. If it’s a worn membrane, a corroded terminal, or a failed speaker cone, we can rebuild it. But if water has wicked into the board or a nearby lightning strike overloaded it, you’re better off with a new part. Call (817) 241-4067 and describe what it’s doing; we’ll give you an honest answer before we come out.
Most keypad replacements take an hour to two hours on site, including reprogramming your codes. Telephone entry systems take a little longer because of the extra wiring and phone module settings.
We keep DoorKing keypads, membranes, intercom boards, and weather seals on the truck, and our shop stocks accessories for LiftMaster, Mighty Mule, and Ghost Controls systems too. If it’s a rare Access Plus board, we can usually have it in hand within a day or two while we do the site wiring check in the same trip.
Just give me a call - I’ll pick up. That’s Hal Gatewood’s direct line to how we do business. We’ll talk through what you’re seeing, and if we can save you the trip charge by fixing it over the phone, we will. If not, we’ll come out, quote the job in writing, and get your gate talking again.
