DoorKing Keypad & Intercom Repair: The Hempstead Owner’s Guide

DoorKing keypad and intercom repair in Hempstead typically runs $240 to $480 installed, depending on whether we’re replacing the keypad face, the intercom board, or the full unit. Most jobs are same-day when we have the part on the truck, which we usually do for DoorKing models installed across Nassau County. Owners usually discover the failure the hard way: a guest calls from the street because the intercom sounds dead, or the keypad stops accepting a code that worked the week before. Sometimes the gate still opens with a remote or a loop detector, so the problem gets ignored until someone is locked out at the worst moment.

Which DoorKing Models This Applies To

We work on the DoorKing entry systems most common in Hempstead: the 1802, 1803, and 1812 keypad models, plus the 1814 and 1816 telephone/intercom entry systems. The 1800-series keypads look similar from the outside, but the internal boards and keypad ribbons are not interchangeable across every revision. The model number is printed on a small silver label inside the keypad housing; if the label is faded or missing, a photo of the unit sent to us before the visit helps our tech pull the right part before rolling out. DoorKing changed keypad connectors around 2015, so a 2009 keypad face will not plug into a 2019 board without a pigtail adapter. On the intercom side, the 1814 uses a different power supply than the 1816, and an aftermarket transformer that matches neither will cook the board in a season. OEM DoorKing parts cost more than aftermarket equivalents, but on keypads specifically we prefer OEM keypad membranes: the aftermarket silicone faces we’ve tested stiffen in Long Island cold and start registering phantom keystrokes within eighteen months.

Signs Your DoorKing Keypad & Intercom Is Failing

• Keys register late or not at all. The silicone membrane under the metal keys loses elasticity over time. You’ll press “9” and nothing happens, then three digits appear at once. This is a worn keypad face, not a wire problem.
• Intermittent buzzer or dead intercom audio. The speaker in a 1814 or 1816 sits in an unsealed housing, and years of salt air and humidity from the South Shore corrode the speaker terminals. You’ll hear crackling first, then silence.
• Gate opens by itself at night. We see this most often on older 1802 keypads where moisture has bridged traces on the keypad board. The board reads a phantom code and signals the operator to open. It’s a security issue, not a glitch to wait out.
• One code works, all the other codes stopped. DoorKing boards store codes in memory blocks. When the board’s battery-backed memory starts failing, it loses blocks inconsistently. The problem isn’t the keypad, it’s the board, and swapping only the face won’t fix it.
• Call button dials nothing or rings the wrong unit. On telephone-entry systems, a failed relay or a corrupt directory chip causes this. In Hempstead multi-dwelling properties near Hofstra, we replace the same relay module on 1816 units year after year.

Replacement Cost & What’s Included

In Hempstead, expect $240 to $480 installed for most DoorKing keypad and intercom repairs. A keypad face or membrane replacement runs $240 to $340. A full keypad board or intercom board swap runs $350 to $480 when the board is ordered from DoorKing. What drives the spread is the part itself: an OEM 1812 keypad assembly costs more than an 1802 face, and an 1816 intercom board is the most expensive single board in the DoorKing residential line. Every bill includes the part, the labor to install and test it, and a written price agreed to before any work starts. The number does not move after the job is open. Our guarantee on the repair is in writing and covers a full year. The pricing table below reflects what Hempstead homeowners typically pay with us.

DIY or Call Us?

A homeowner can safely check the obvious things: confirm the unit has power at the breaker, wipe the keypad face with a dry cloth to rule out conductive grime, and verify the gate’s master switch is not in “hold” or “service” mode. Past that point, we’d rather you call us. DoorKing keypads run on low voltage, but the boards are static-sensitive, and a single short across the wrong pair of terminals kills a board that was otherwise repairable. We’ve also seen well-meaning owners strip the tamper screws on 1803 housings trying to open them with the wrong bit. If the diagnostic steps above don’t restore function, call (516) 559-4870 and we’ll send a background-checked, uniformed technician with the parts already matched to your model.
