Linear Keypad & Intercom Repair Nationwide

Linear Keypad & Intercom Repair: The Fort Worth Owner’s Guide

Linear keypad and intercom repair in Fort Worth typically runs $185 – $420 installed, depending on whether we’re replacing a keypad face, swapping a dead intercom board, or rewiring a corroded terminal strip. Most jobs are done the same day from parts we keep on the truck, because Linear’s older M-Series and AE-Series keypads are among the most common access-control components on residential gates across Tarrant County. The usual story is: the keypad works sometimes, eats codes, or goes dark entirely after a hard rain. You stand at the gate pressing buttons, nothing happens, and then you realize the intercom hasn’t rung in weeks.

We’re Calder Gate Repair Fort Worth, part of the Relay Home Co. family since 2009. We’re an independent gate repair specialist, and we’re not affiliated with Linear or its parent company. Nico Alvarez and our crew have been pulling apart Linear keypads and intercoms in Fort Worth for years now, including a fair number of older swing gates out in Summerfields where weather-baked sun and electrical surges do a number on access hardware.

Which Linear Models This Applies To

Linear’s residential gate access line spans three generations that we see in Fort Worth every week: the older M-Series keypads (M3, M3X, M5), the AE-series (AE-100, AE-2000, AE-500), and the newer Am10/AM-KP door and gate controllers. The AE-100 and AE-2000 in particular show up constantly on swing gates that were installed between roughly 1998 and 2012. If you can open the keypad face and read a small printed model sticker on the back of the circuit board, that’s the cleanest way to identify what you have.

The compatibility gotcha with Linear is that their keypad wiring and their intercom wiring are two different circuits, and older M-Series keypads used a proprietary 5-wire hookup that many aftermarket “universal” keypads don’t cleanly support. We carry both OEM Linear replacement parts and quality aftermarket equivalents that match the original wiring footprint. For intercom systems specifically, the board revision matters more than the housing: an AE-2000 intercom made after 2009 has a different terminal layout than the earlier revision, and swapping them without re-terminating the station cable is how we’ve seen “new board, same dead intercom” service calls. We identify the right part by opening the housing, reading the board silk-screen label, and matching it to the opener’s control inputs before quoting anything.

Signs Your Linear Keypad & Intercom Repair Is Failing

• Backlight tests good but codes stopped working. The keypad’s membrane or button contacts typically wear out first. Linear’s silicone button pads develop micro-tears after years of Texas sun exposure, and once moisture gets into the button matrix, pressing “1234” gets you “1” and nothing else.
• One or two buttons require hard pressing. That’s usually conductive wear on the PCB contact surface under the buttons. You can clean the contact pad temporarily, but once the carbon traces start lifting, it’s a replacement part call.
• Gate opens intermittently from the keypad but not the remote. This is typically a worn relay on the keypad’s output side, or a loose terminal connection where the keypad ties into the operator’s “free exit / open” input. Loose screw terminals on Linear’s AE-series keypads are the single most common wiring fault we see.
• Intercom audio is faint, buzzing, or one-directional. The microphone capsule or speaker cone usually fails first on Linear intercom systems, especially on south-facing posts where Texas heat bakes the plastic grill and dries out the speaker surround. Buzzing usually traces to a failing electrolytic capacitor on the intercom board.
• Keypad or intercom stays dead after a power cycle. On Linear equipment, this is often a blown surge protection component inside the keypad housing. Fort Worth’s lightning storms and power dips regularly kill the protection diode before the main circuit goes. That’s a part we keep on the truck specifically because of how often we see it here.

Replacement Cost & What’s Included

Every repair is quoted in writing before we turn a wrench, and the number you agree to is the number on your invoice. Here’s what Linear keypad and intercom work typically runs in Fort Worth:

These prices include the part, labor, re-terminating connectors where needed, and a function test of the entire access circuit before we leave. The spread comes from part type (OEM versus aftermarket) and how much rework the station wiring needs once we open the box. Everything we install carries our 365-Day Done Right Promise: if the repair fails within a year, we return at no charge, no questions, no arguing about whose fault it was.

DIY or Call Us?

Keypad and intercom work is low-voltage, so it’s not the electrocution risk of a 120V line. What gets homeowners in trouble with Linear gear is upstream of the keypad itself: the keypad sends a signal to the gate operator’s control board, and if you short the wrong two terminals during a swap, you can take out the control board. A $40 keypad swap turning into a $600 operator board replacement happens more often than people want to admit.

What you can safely do: check for visible corrosion, confirm the breaker that feeds the operator hasn’t tripped, and press each button to see which ones respond. What you shouldn’t do: attempt to rewire a Linear keypad from a YouTube video that assumes the wire colors match your exact model. They often don’t. Tell me what it’s doing, or not doing, and I’ll tell you exactly what it needs. If the answer sounds like a deep dive, call (682) 432-9830 and we’ll quote it straight.
