AfterDoorKing Access Control Installation: The Richardson Owner’s Guide
DoorKing access control installation in Richardson typically runs $450 to $1,100 installed, depending on whether we’re swapping a failed keypad, adding a telephone entry system, or wiring a full card reader with a mag lock. Most single-component replacements are done in one visit, and we keep the most common DoorKing parts on the truck. You usually discover the problem the day the keypad stops talking to the board, or the telephone entry unit rings but won’t open the gate, or the card reader lights up and ignores every credential waved at it.
What we see most often in Richardson is a DoorKing 1812 or 1838 series keypad that’s been baking in full Texas sun for eight or nine years until the membrane cracks or the internal contacts corrode from humidity. The system worked fine the day before. Then it didn’t. That’s the nature of access control: it fails quietly, and the first sign is usually you standing at the keypad with a bag of groceries in one hand and a guest waiting at the gate.
Which DoorKing Models This Applies To
DoorKing has been making access control hardware since 1948, and over the decades they’ve produced a long line of keypads, telephone entry systems, card readers, and controllers. The most common units we service in Richardson are the 1812 surface-mount keypad, the 1838 flush-mount keypad, the 1814 telephone entry system, the 1834 and 1837 access control systems, and the 8050 and 9150 slide and swing gate operators with built-in access control boards. Older 1500-series keypads still show up on gates that have been in place since the 1990s.
Here’s the compatibility gotcha most owners don’t know: DoorKing keypads and controllers are not all interchangeable across generations. A keypad wired for a 1990s-era 1504 control board will not simply drop into a newer 1838 system without a wiring adaption and sometimes a firmware mismatch on the board itself. We identify the right part by pulling the model number off the back of the unit or the board inside the operator box, not by eyeballing the faceplate. On the OEM-versus-aftermarket question, DoorKing OEM parts are well built and consistently available, but they’re priced like OEM parts. For common wear items like keypad membranes and micro-switches, we’ve had good results with quality aftermarket equivalents that match the OEM spec. For control boards and telephone entry logic boards, we recommend OEM every time. A no-name board that’s “compatible” is the fastest way to turn a $300 repair into an $800 replacement.
Signs Your DoorKing Access Control Installation Is Failing
- The keypad accepts the code but doesn’t open the gate. The keypad membrane and micro-switches are working, but the relay on the control board isn’t firing. That’s usually a failed relay or a corroded connection at the board, not the keypad itself.
- Certain buttons require a hard press to register, or they double-type. The membrane has worn through or the switch contacts inside have oxidized. This gets worse in Richardson’s humid summers, and once it starts, it doesn’t heal itself.
- The telephone entry unit rings the house but no one can hear the caller, or the caller can’t hear you. The audio circuit or the buzzer relay on the 1814 board has failed. Sometimes it’s a bad microphone; more often it’s a cold solder joint that opens when the board heats up in the afternoon.
- The gate opens on its own, or intermittently ignores commands. This is usually water intrusion at the keypad or a failing ribbon cable between the faceplate and the board. The intermittent part is what makes it dangerous: a gate that might open when it shouldn’t is a bigger problem than one that won’t open at all.
- The card reader beeps but the gate doesn’t move. The reader is reading the card. The controller isn’t acting on it. On DoorKing systems, that’s typically a Weigand wiring issue or a blown output transistor on the access controller, and both are testable in under twenty minutes with a multimeter.
Replacement Cost & What’s Included
For Richardson homeowners, installed DoorKing access control work lands in a few ranges. A keypad replacement (OEM DoorKing 1812 or 1838) typically runs $450 to $650 installed, including the part, the service call, wiring, and programming. A telephone entry system replacement runs $650 to $950. A full access control package with a card reader, keypad, mag lock, and exit loop starts around $900 and goes up from there depending on wire runs and the condition of the existing gate operator. Parts are typically 40 to 60 percent of the total; the rest is labor and the guarantee that it’s wired correctly.

DIY or Call Us?
There are a few things an owner can safely check before calling. Is the breaker for the gate operator tripped? Is the keypad face cracked or full of water? Is the telephone entry unit’s phone line (or VOIP adapter) actually connected? Those three checks solve a surprising number of “dead” systems. What we don’t recommend is opening the operator box and probing the control board with a meter unless you’re comfortable working around 120V and low-voltage logic circuits. DoorKing boards run on step-down transformers that can still bite, and one short across the wrong two terminals will take out the board, the transformer, and sometimes the gate operator’s main board along with it.
If the keypad is dead, the board is suspect, or the wiring has been chewed by the squirrels that love Richardson’s oak-lined neighborhoods, give us a call at (903) 627-2906. Victor Salinas and the team will get eyes on it, tell you exactly what it needs, and quote you a number before any work begins.
FAQs
A well-installed OEM DoorKing keypad typically lasts 7 to 10 years in Richardson, though south-facing full-sun mounts can kill a membrane in 5. Aftermarket membranes tend to run 3 to 5 years. We recommend a shaded enclosure or a sun shield on any new install; it’s a cheap way to add years to the part.
Sometimes. A keypad with a worn membrane but a functioning board can often be rebuilt with a new membrane and micro-switch kit, which runs less than a full unit. A control board with a single blown relay can occasionally be repaired at the component level, but most boards from the 2000s and later are surface-mount construction, which means replacement is faster and more reliable. We’ll tell you which one applies to your unit before any money changes hands.
A straightforward keypad swap takes 45 to 90 minutes including programming. A telephone entry replacement runs 90 minutes to 2 hours. A full access control package with new readers, a mag lock, and wire runs is a half-day job. Most Richardson installs are completed in a single visit.
We keep the most commonly needed DoorKing parts on the truck: 1812 and 1838 keypads, micro-switch kits, relay boards, and common wiring harnesses. Less common items like a full 1814 telephone entry board usually arrive from our supplier within 1 to 2 business days. We work across eight other gate-automation brands, LiftMaster, Mighty Mule, Ghost Controls, FAAC, BFT, Linear, Viking, and Elite, so whatever is on your driveway, we’re equipped to handle it on the first visit.
